In the semiconductor industry, PTFE (polytetrafluoroethylene) is widely used in the production of cassettes and baths due to its exceptional properties. Here’s an overview of their applications and advantages: Applications of PTFE Cassettes and Baths 1. Wafer Handling: - PTFE cassettes are used to safely store and transport silicon wafers during various processing steps. Their smooth surface reduces the risk of contamination and damage to the wafers. 2. Chemical Compatibility: - PTFE baths are utilized in wet processing applications, such as etching and cleaning. They provide a highly resistant environment for aggressive chemicals, ensuring that the materials do not react with the solutions. 3. Temperature Resistance: - PTFE cassettes and baths can withstand a wide range of temperatures, making them suitable for processes that involve heating or cooling. 4. Corrosion Resistance: - Due to their outstanding chemical resistance, PTFE cassettes and baths protect the integrity of the semiconductor manufacturing process by preventing corrosion from harsh chemicals. 5. Fluid Dynamics: - PTFE baths are designed to facilitate optimal fluid flow, ensuring effective and uniform chemical distribution during processes like wet etching and cleaning. Advantages of PTFE Cassettes and Baths 1. Low Friction: - PTFE has a low coefficient of friction, which minimizes wear and tear during wafer handling and improves the efficiency of automated systems. 2. High Purity: - The non-reactive nature of PTFE ensures that there is no leaching of contaminants into the chemicals or onto the wafers, maintaining high purity levels critical for semiconductor fabrication. 3. Ease of Cleaning: - PTFE's smooth surface makes it easy to clean, reducing downtime and ensuring that equipment remains contamination-free between processes. 4. Durability: - PTFE materials are known for their longevity and can endure the demanding conditions of semiconductor manufacturing without degrading. 5. Cost-Effectiveness: - While PTFE materials may have a higher initial cost, their durability and resistance to chemicals lead to lower maintenance and replacement costs over time. Overall, PTFE cassettes and baths are essential components in semiconductor manufacturing, offering reliable performance and superior protection against the challenges posed by chemical processes and wafer handling. web: https://www.njbinglab.com Phone/Whatsapp/ Wechat :+8615805176994 Mail: rossnjbzh@gmail.com / rossg@njbinglab.com

Phenolic Foam Insulation Pipe is a new pipe insulation material formed by cutting. The product has super insulation effect, convenient construction and neat appearance. The main body of phenolic foam insulation pipe is composed of an external protective layer, phenolic foam, male and female mouths, and sealing tape. The external protective layer usually uses materials such as aluminum foil, reinforced aluminum foil, aluminum foil, etc. based on the specific construction and insulation characteristics of the pipeline. Due to its strong environmental adaptability, resistance to high and low temperatures, resistance to deformation, and reflection of sunlight temperature, aluminum foil has been widely used for external protection. The male and female joints are important institutions in the design of insulation pipes. Its Z-shaped structure not only effectively isolates insulation and conduction, but also plays a role in size buffering during actual construction.

The ventilation phenolic board is usually composed of phenolic foam in the middle layer and embossed aluminum foil in the inner and outer layers. There are also single-sided color steel phenolic duct panels, double-sided color steel phenolic duct panels, and special flanges and other accessories that can be made into phenolic composite ducts for central air conditioning ventilation. In terms of bending resistance, compression resistance, and processing performance, it is very good and basically meets the requirements for the use of air conditioning ventilation pipes. Advantages of ventilated phenolic panels: Good insulation, which can greatly reduce the heat dissipation loss of air conditioning The thermal conductivity of ventilated phenolic panels is 0.020~0.025W/(m · k), while the thermal conductivity of galvanized steel plates and fiberglass ducts is much higher. In addition, the unique connection method of the ventilation phenolic board ensures excellent airtightness of the ventilation system, which is close to 8 times that of galvanized steel plate ducts. Some data show that when conveying the same heat (cold) amount, the heat loss of galvanized steel duct is 15%, that of glass fiber reinforced plastic duct is 8%, and that of phenolic foam insulation material duct is less than 2%. Lightweight, can reduce building load, and easy to install

Rooftop insulation phenolic board can not only provide insulation, but also serve as a waterproof, moisture-proof, and soundproof material. Usually, in order to increase the insulation effect, many insulation materials increase their thickness, which greatly increases the usable area during construction and occupies a large indoor space. The aluminum foil phenolic insulation board can achieve a density of 100kg/m ³ and a thickness of 2cm. The aluminum foil covering can effectively resist heat source radiation and block heat transfer. The phenolic material in the middle can effectively isolate cold and hot air and water molecules because of its closed cell foam structure, with low thermal conductivity and good thermal insulation effect. Due to the high density of phenolic materials, the thickness of the board is 2cm, and the hardness is also sufficient. The construction is convenient during use, the board occupies less space, and the insulation effect is not inferior to other insulation materials with a thickness of 5cm or even thicker.

When it comes to the choice of floor heating insulation materials, phenolic insulation boards are gradually becoming the first choice in the market due to their excellent performance. Compared with traditional extruded boards, phenolic insulation boards have significant advantages in thermal insulation performance, fire resistance, environmental protection and service life, providing a strong guarantee for the stable and efficient operation of floor heating systems. First of all, the thermal conductivity of phenolic insulation board is as low as 0.021W/m·K, Phenolic insulation board has the same R-value and thermal insulation effect as PIR material and better fire retardant performancewhich is much lower than the thermal conductivity of extruded board, which is about 0.030W/m·K. This means that the phenolic insulation board can provide better thermal insulation effect at the same thickness, effectively reducing the heat loss of the floor heating system, thereby saving energy costs.

The most prominent feature of exterior wall insulation phenolic board is insulation, non combustible, and resistance to high-temperature deformation. It overcomes the shortcomings of the original foamed plastic insulation material, such as flammability, smoke and deformation in case of heat, and retains the characteristics of the original foamed plastic insulation material, such as light weight and convenient construction. 1) Excellent fire resistance performance Phenolic foam is used as the thermal insulation layer, which is compounded with other materials for building thermal insulation. The possibility of external insulation fire is fundamentally eliminated. The temperature range is -196 ℃~+120 ℃.

The NJbinglab PFA slender gas washing bottle offers several advantages that make it an excellent choice for various applications. 1. Corrosion Resistance: PFA (Perfluoroalkoxy) is highly resistant to a wide range of chemicals, making the bottle ideal for use with aggressive acids and bases. 2. Pressure Resistance: The material can withstand higher pressure without compromising structural integrity, ensuring safe operation in various experimental conditions. 3. High-Temperature Tolerance: PFA can endure high temperatures, allowing it to be used in applications that involve heat without degrading or releasing harmful substances. 4. Stable Base: The design features a stable base that minimizes the risk of tipping over, providing safety and reliability during use. Applications The PFA slender gas washing bottle is commonly used in industries such as pharmaceuticals, chemical processing, environmental testing, and laboratory research, where chemical resistance and stability are critical. Its robust properties make it suitable for processes that require safe handling of volatile or corrosive substances. web: https://www.njbinglab.com Phone/Whatsapp/ Wechat :+8615805176994 Mail: rossnjbzh@gmail.com / rossg@njbinglab.com
