GLPOLY Thermally Conductive Insulator Takes Bergquist Sil-Pad as Benchmark

It sounds easy and simple to make thermally conductive insulator, but there are just two or three high quality thermal insulator manufacturers, GLPOLY is one of them.

For many thermal management engineer, Bergquist thermally conductive insulator is preferred, or take it as benchmark even they don’t use it finally. The main raw materials are fiberglass(or PI), silicone oil and thermally conductive powder. it is very simple, isn’t it? but few of manfacturers can make quality thermal insulator with high performance and reliability. There are always some problems, either the low thermal performance or dielectric strength.

We are not undervaluing peers, I have experienced that some peers bought thermally conductive insulator from us. GLPOLY is one of the leading expert in the development and production of thermal insulator, taking Bergquist etc as benchmark.

A motorized chair mannufacturer consulted us about thermally conductive insulator. They wanted to use a local alternative product to replace Bergquist Sil-Pad 900S, requesting an equivalent of performance or better. The customer had tested many similar samples before and failed each of them, because the temperature rise of chip is 95 degree, exceeding design requirement. Customer is misguided in expecting an higher thermal conductivity.

We recommended a thermal insulator XK-F20ST1 with 2.3W/mK, but customer doubted whether the thermal conductivit is high enough, “the thermal conductivity of samples we had tested before were 2.0W/mK, is 2.3W/mK enough?“. Actually, in order to enhance dielectric strength, some suppliers use materials which is detremtal to heat transfer and customer doesn’t know detail. We suggest customer test it first, “the cost high performance thermal matieral is proportional to thermal conductivity, we must consider the necessary of using a higher performance thermal material. If it is unworkable, we’ll provide another high performance product”.

Customer accepted our suggestion and tested the 2.3W/mK thermally conductive insulator. Finally, customer was surprised by result, during the entire testing process, the temperature never exceeded 80 degree. Compared with Bergquist Sil-Pad 900S, GLPOLY XK-F20ST1 thermally conductive insulator provided high thermal performance as Sil-Pad 900S does, at the meantime, with a favorable price and shorter lead time.

GLPOLY XK-F20ST1 is a high performance, electrical insulation thermally conductive insulator with low thermal impedance 0.22℃in2/W. It has a dielectric voltage of 3.5kV, providing excellent reliability. XK-F20ST1 thermal insulator is one or two sided soft-tack for ease of assembly. The soft natura makes interface contact more fully, optimizing heat transfer.

GLPOLY has been providing thermal insulator for DJI and Han’s Laser etc top-class enterprises for several years. GLPOLY help keep you design beakthroughs with complete portfolio of thermal management materials.
