GLPOLY thermal gap pad XK-P60-PUUTY is the only one that can substitute for Laird Tflex HD700 with high thermal performance and high compression. You will find that a lot of suppliers said they can provide substitute for Laird Tflex HD700 because our product provides the same thermal conductivity. Is it true? When you review the datasheet or you know even just a little about thermal gap pad, you can find that thermal conductivity is not the most important, it does not meam thermal cnductivity is not vital, but compared to the products which is with similar thermal performance, Laird Tflex HD700 provides higher compression and conformability. With benchmark of Tflex HD700, GLPOLY released XK-P60-PUTTY with high performance and compression as a perfect substitute for Tflex HD700. A customer searched us from internet and asked “can you really provide a perfect alternative part to Laird Tflex HD700 or just provide a similar product”. “Perfect alternative with thermal and physical properties, test result will show you what it really is”. We provided a XK-P60-PUTTY in 1.5mm thick after customer gave me application information of power and gap size. The test last for two weeks, customer was satisfied with result when test was finished. Customer told me that they bought a Laird Tflex HD700 from electronic material supplier on internet while he took samples from me for comparing. The temperature is 65 degree when performing with Tflex HD700, it was good, but GLPOLY thermal gap pad was better, the temperature was maintained under 60 degree. The chief engineer sent me a message, just one word ”excellent”. GLPOLY thermal gap pad XK-P60-PUTTY is high performance, high compression gap filling material with thermal conductivity of 6.0W/mK. It provides high deflection under low compressive forces, decreasing stress on component and avoiding component failures. GLPOLY is qualified partner to Huawei, ZTE and DJI, also GLPOLY thermal materials have been applied in new energy electric vehicle. GLPOLY is committed to delivering advanced thermal management solutions for top class clients.

GLPOLY thermal gel is non-dry out, non drip off, extending service life of devices and defeating 95% of competitors. Most of competitive products are similar to thermal silicone grease with a short service life, one or two years. Rivals’ thermal gel will volatilize and cure, causing thermal conducting to fail. GLPOLY thermal gel features ultra low thermal resistance, non-cure, non-drip off, just few of thermal management materials suppliers can make it. this is not bragging, it is truth. A robot design company found me and consulted about thermal interface materials with thermal conductivity of 5.0W/mK or higher and 5-year service life. As precise devices require high thermal performance and paste materials provide higher performance than solid materials, we recommended XK-G50 thermal gel to customer. But customer reply rapidly with doubt, “is thermal gel workable? We are using a thermal gel in our products, it performance well at the beginning, but we need to replace it once a year when it cures and fail to transmit heat.” This customer used a famous brand in Shenzhen. We knew about this situation much, the thermal gel will cure like thermal silicone grease in one year, and it drips off polluting other components. I assured customer that GLPOLY thermal gel will not cure in six years and it provdes a longer life than device’s. I suggested customer make an accelerated aging test to shorten design cycle. Customer accepted my suggestion and fixed test conditions: high temperture 150 degree centigrade, 720 hours, changes were within 5%. Comparing with rival’s changes of 10%, GLPOLY’s standard is much more rigorous. One month later, customer opened test chamber and found that GLPOLY XK-G50 thermal gel remained paste status. Performance test showed that changes of thermal conductivity and thermal impedance were less than 3%. “this is the best what I had test ever.” GLPOLY XK-G50 had been listed in customer’s supplier system. There is no quality complaint for nine consecutive years. GLPOLY XK-G50 thermal gel provides ultra low thermal impedance of 0.001℃in2/W, it wets out interfaces decreasing contact thermal resistance. XK-G50 had been verified by the third party for shocking test and aging test. Now GLPOLY is qualified partner to DJI, ZTE and GAC Auto. If there is only one supplier can meet your thermal management requirements, it would be GLPOLY.

80% of GLPOLY thermal management materials is of same quality level as top-class brands, the remaining 20% of products outperforms them I heard that a lot of domestic rivals said their products can substitutes for products of top-class brand, seems like it was easy to find an anternative in China. But that was not the case. Usually, customer can’t find an alternative product with excellent integrated performance from a dozen supplier, either thermal or physical properties fail to meet requirements. GLPOLY had catched up with top-class brand with integrated performance. A power supply technology company from Shanghai consulted with me about an alternative to Fujipoly GR-ae, requesting a thermal conductivity of 1.5W/mK, especially low hardness of Shore00 15 for low compressive force, decreasing stress on component thus decreasing component failures. I understood customer’s requirements, the greatest advantages of Fujipoly GR-ae are low hardness, low stress and high compression rate. There is no problem over thermal conductivity to most of suppliers but the hardness. So I recommended XK-P20 thermal gap pad with a thermal coductivity of 1.5W/mK to customerand and suggested he tested material in realistic settings. Test lasted for three weeks, data was perfect as we expected, thermal conductivity and hardness of GLPOLY thermal pad XK-P20, 1.5W/mK were equivalent to Fujipoly GR-ae, but thermal resistance is one fourth lower than that of Fujipoly GR-ae. That meant GLPOLY XK-P20 prvoided more exellent thermal properties. Customer decided to use XK-P20 thermal pad instead of Fujipoly. We had not received quality complaint for two years since XK-P20 thermal gap pad had been applied in volume production. GLPOLY has been providing thermal management materials for NIO electric vehicle, GAC NE and Chinese Academy of Sciences, especially, GLPOLY thermal management materials has been applied to military equipments in 2019 National Day Parade. GLPOLY thermal management materials are of excellent quality as top-class brands and it strives to exceed top class brands.

GLPOLY thermal gap pad XK-P80 is a dark horse in thermal interface materials industry, designed to solve thermal management problem of 5G telecom equipment. It is constructive to said that XK-P80 thermal gap pad is a preferred thermal solution for thermal management of 5G telecom equipment. It was said that there were many thermal interface materials can be applied to 5G telecom equipment thermal management, actually, to many thermal management engineers, it was not easy to find a proper thermal interface materials for 5G telecom applications, they found that performance of most of thermal interface materials were inconsistent with what they claimed, lower performance, low reliability etc., this was true. GLPOLY has always been at the leading edge of technological development of thermal interface materials. In order to fulfill the demand of 5G telecom equipment thermal management, GLPOLY had developed a thermal gap pad with a thermal conductivity of 8.0W/mK. This thermal gap pad had been verified by DT mobile, a leading telecommunication equipment manufacturer in China. No matter the thermal performance, reliability or service life, GLPOLY thermal gap pad XK-P80 could met customer’s requirements.

GLPOLY Thermal Gap Pad-To solve Thermal Management Challenges of Etching Machine GLPOLY XK-P30 thermal gap pad has been applied to etching machine, improving thermal management. Chips are in short supply in 2021, many enterprises are working towards producing chips in-house and casting off the inhibitions of US enterprises. It is reported that AMEC had launched a 5 nm etching machine. GLPOLY met this customer in electronica China Fair in March. The engineer told us he used an imported thermal gap pad in the past, his team wanted to use a local product due to logistics complexity. “The principal concern was performance,”he said, “I have tested several products of famous brands, the performance were insufficient, and test results did not match the specification really.” We promised that all indexes were true and never worse than data marked on specification. We delivered samples to customer in three days. In the next four months, customer completed extreme temperature cycling and shock test. Devices run stably and temperature rise was lower than they expected. In July, we got formal order from this customer. GLPOLY has collaborated with leading players in each sector such as LG, DJI, DT Mobile, GAC NE Motor, Lixiang Motor, NIO Motor and more, providing them with exceptional performance thermal interface materials to help them design devices that run cooler and more reliably. And GLPOLY is ready to help you solve thermal management challenges too. Call it a day, have a break. I’ll come chatter & nag tomorrow.

Thermal conductivity is not the only criteria to judge the performance of thermal management materials, compression, thermal resistance and application condition are to be taken into account. Some purchasing officers don’t know well about thermal interface materials, they just pay attention to thermal conductivity, also many suppliers only stress thermal conductivity while ignoring other factors. A robot manufacrurer consulted with me about high performance thermal gap pad, requesting a thermal conductivity of 5.0W/mK or higher, also low hardness, low stress are needed because this thermal gap pad will be applied to a fragile chip. After learned about the application, I didn’t think it is necessary to use a thermal pad with a thermal conductivity of 5.0W/mK according to my experiences, of course it will not hinder heat transfer but increase cost. I recommended a 3.0W/mK thermal gap pad which can meet design requirement. “Actually we have tested 3.0W/mK thermal pad already, but performance is not good, temperature rise exceeded our expectation.” In addition, heatsink will be fastened at either end, probably it bend middle part, making contact untight. So I suggest customer use thermal gel XK-G40 instead of thermal gap filler pad. thermal gel will deflect under low compressive force, decreasing stress on component, especially low thermal resistance. Customer accepted my suggestion and wanted to test this thermal gel. Test lasted for two weeks, temperature is as expected at 60 degree, thermal performance is excellent. Customer fixed thermal gel XK-G40 solution on site. There is no quality issue raised since this project have been launched for two years. GLPOLY has provided thermal management materials for DJI and Han’s Laser for many years and without complaint in nine consecutive years.

High performance, high compression rate, low stress. GLPOLY XK-P25 thermal gap pad is the only one that can substitute for Fujipoly GR25A. Since 2008, GLPOLY has been entering thermal management materials industry for more than ten years. It is always at the leading edge of development of thermal materials, competing with top brand such as Fujipoly, Bergquist or Chomerics. Taking Fujipoly GR25A and GLPOLY XK-P25 thermal gap pad as an example, we will see what the difference is between these two products. Once, we received a request for Fujipoly GR25A. Actually, we don’t have any Fujipoly products because we are not an distributor. We are an manufacturer and build our own brand—GLPOLY. Though we can not offer GR25A, we recommended a similar product GLPOLY XK-P25 thermal pad. Many customers always think foreign brands are much better than domestic brands, no matter the quality of raw materials or performance of product, so did this customer. ”Even if it is not equivalent to GR25A, please make the difference as small as possible.” customer said with doubt. We are confident that XK-P25 thermal pad provided excellent performance as GR25A, because we had tested this material for many times and it has been being in volume production for ten years. Test results is the powerful proof. GLPOLY XK-P25 offered a thermal conductivity of 2.5W/mK and a thermal impedance of 0.35℃in2/W, they were almost the same to GR25A’s. GLPOLY thermal management materials has been applying to EV battery pack, automotive electronics and military equipment, to help keep your devices performing at their best.

Some customers gave us a master data sheet from other suppliers for comparing when they wanted to select a thermal gap pad from GLPOLY, all requirements should be similar. For example, the original data sheet marked”fiberglass or PI reinforced”, they need a fiberglass reinforced material too, even they don’t know what function or effect it acts. Firstly, the fiberglass or PI will increase thermal resistance. Both of them will not act as thermal interface materials, reducing thermal performance. Secondly, cost rise. If you need a same thermal conductivity after fiberglass or PI reinforced, we need to use a higher performance material, costs will rise by 30%. At the meantime, the cost of process will be inceased too, because it’s more sophisticated. Also don’t forget the cost of fiberglass or PI. Last week, one solar equipment manufacturer contacted me and ask if we can make a thermal gap pad meeting his requirements. Actually, it just was a regular product, 2.0W/mK of thermal conductivity, Shore00 50 hardness, 4.0mm thickness, one sided fiberglass reinforced. I asked the cutomer why he request fiberglass reinforcement because it affects heat transfer greatly. The custmer get this data sheet from another supplier, said “it increases tear resistance for easy assembly”. I understand customer’s concerns, but according to our experience, a thermal silicone pad with Shore00 50 hardness and 4.0mm thickness provides enough tensile strength and tear resistance for assembly. Finally, we sent samples without reinforcement to customer, and test went well. We will recommend a better solution for you and keeping your devices performing steady.

The Benefits That Silicone-free Thermal Gel Brings to You More Than Applying To Silicone-sensitive Application As a thermal management materials supplier, we often received questions from customer. For example, What’s the difference between silicone and silicone-free based thermal materials? Which material provides better performance, thermal pad or liquid thermal materials? Do liquid thermal material and thermal gap provide same performance with the same thermal conductivity? Take GLPOLY XK-GN30 as an example to illustrate briefly. Silicone-free thermal interface materials has no silicone content, it is ideal for silicone-sensitive applications which has a optical window, such as camera, LED lights, Automotive headlights, avoiding siloxane volatiles and preventing them from atomizing. XK-GN30 is a high performance, thermally conductive, one-component packaged, liquid gap filling material with a thermal conductivity of 3.0W/mK. as we know, liquid thermal material has a low thermal impedance. With the same thermal conductivity, XK-GN30 silicone-free thermal gel has a thermal resistance of 0.01℃in2/W, comparing with a 3.0W/mK thermal gap pad, thermal impedance of XK-GN30 non-silicone thermal gel is one twentieth of that of thermal gap pad. GLPOLY XK-GN30 provides a ultra thin bondline thickness of 0.09mm, making heat transfer fast. Comparing with thermal gap pad, usually the thinnest thicnkess is 0.3mm. XK-GN30 is suitable for filling the intricate gaps and voids, it deflects under low compressive forces improving interface contact. Thermal gap pad never fill gaps as complete as liquid thermal material. GLPOLY XK-GN30 silicone-free thermal gel has been applied to industrial camera in volume production for 5 years, it provides high performance and reliability, helps keep your devices performing at their best and extending service life.

Hard to find an alternative to Laird Tflex 900 in local Chinese market in the past. It changed a lot in recent years. At least, GLPOLY is able to compete with top class brands such as Laird, Bergquist, Fujipoly or 3M. Many manufacturers said that their products are alternative to top class products as mentioned above, but if you test the objects, you can always find some probems, parameters mismatched. For instance, some manufacturers made the thermal conductivity of 8.0W/mK, which is as high as Laird Tflex900’s, but the hardness is beyond expectation, it is detrimental to heat transfer. GLPOLY can provide an excellent alternative to Laird Tflex900, no matter thermal properties or physical properties. Here is a case. One millimater wave radar manufacturer consulted with us about high performance thermal gap pad which is used for replacing Laird Tflex900. Some properties must be consistent with that of Laird Tflex900. We recommended GLPOLY XK-P80 thermal gap pad to customer. This thermal pad is a high thermal performance, electrical insulation and highly conformable gap filling material with a thermal conductivity of 8.0W/mK. I can imagine that customer will doubt the performance of this thermal gap pad, but test will exhibit detail. Test resulteds showed that both GLPOLY XK-P80 and Laird Tflex900 provided a thermal conductivity of 8.0W/mK, but XK-P80’s thermal imepdance 0.13℃in2/W which is much lower than Laird Tflex900’s. This really surprised customer, “This is only local product that meet our requirements I had tested.” GLPOLY has been providing thermal gap pad and thermal gap filler for some car manufacturers, help resolving problems of battery pack and ECU thermal management, such as NIO GAC etc. GLPOLY is able to provide complete portfolio of thermal management materials including thermal gap pad, two component thermal gap filler, one-part thermal gel, (thermal paste) and silicone-free thermal materials for you to protect your brand reputation for performance and reliability.
