High temperature buffer pads play an important role in industries, automobiles, and electronics. Choosing the appropriate material is crucial for ensuring the performance of the cushioning pad. Below, we will introduce 10 common high-temperature cushion materials, analyze their characteristics and applicable scenarios, and help you make wise decisions.

1、 Silicone gel

Silicone is a widely used high-temperature buffer material with excellent heat resistance and elasticity. Its te mperature resistance range is usually between -60 ° C and+250 ° C, which can effectively absorb vibration and impact forces. Silicone has high chemical stability and is not easily corroded by oil, chemicals, and water, making it suitable for various fields such as automobiles, electronic devices, and medical equipment. Despite the relatively high cost of silicone, its excellent performance makes it the preferred material in many high-temperature applications.

2、 Heat-resistant foam

Heat resistant foam is a buffer material made of polyurethane or polyester with good shock absorption performance and lightweight characteristics, suitable for applications that require weight reduction. Its temperature resistance is generally between -40 ° C and+120 ° C. Although the temperature resistance range is relatively low, it is still an ideal choice in many automotive interiors and electronic equipment. Its soft properties enable heat-resistant foam to effectively fill voids of various shapes.

4、 Polyimide (PI)

PI is a high-performance plastic with excellent high temperature resistance and mechanical strength, with a temperature range of -269 ° C to+400 ° C. PI is particularly widely used in electronic devices due to its excellent electrical insulation and chemical stability. It is suitable for applications that require high temperature resistance, low thermal expansion, and excellent electrical performance, such as aerospace and semiconductor manufacturing. Despite the high cost of PI, its performance makes it worth it in some high-end applications.

5、 Aramid fiber

Aramid fiber is a high-strength synthetic fiber with excellent heat resistance, with a temperature range of -196 ° C to+200 ° C. The wear resistance and impact resistance of aramid fiber make it suitable for protection and buffering in high-temperature environments. Commonly used in fields such as firefighting suits, high-temperature resistant gloves, and automotive components, aramid fiber's lightweight and high-strength properties have made it widely used in safety and protective equipment.

6、 Fiberglass

Fiberglass is a traditional high-temperature buffering material widely used in construction and industrial equipment. Its temperature resistance can generally reach+600 ° C, with high strength and rigidity. Glass fiber not only can resist high temperatures, but also has good chemical resistance, suitable for use in industries such as chemical and metallurgical industries. Despite its poor flexibility, the durability and cost-effectiveness of fiberglass make it a reliable choice in many high-temperature applications.

7、 Polytetrafluoroethylene (PTFE)

Polytetrafluoroethylene (PTFE) is a plastic with excellent chemical stability and high temperature resistance, with a temperature range of -200 ° C to+260 ° C. Its low friction properties make it excellent in sliding parts and sealing applications. PTFE has excellent insulation properties and is suitable for use in electronic and electrical equipment. Despite its high cost, PTFE is an ideal choice for situations that require high heat resistance and chemical stability.

8. Polycarbonate (PC)

Polycarbonate (PC) is a transparent polymer material with good heat resistance, with a temperature range of -40 ° C to+120 ° C. Its excellent impact strength and toughness make it suitable for the production of automotive lighting, electronic casings, and other components. Although its high temperature resistance is not as good as some other materials, polycarbonate is still a popular choice in many applications that require transparency and strength.

9. Aluminum foil

Aluminum foil, as an auxiliary material for high-temperature buffering pads, exhibits outstanding performance in insulation and heat reflection. Aluminum foil is resistant to high temperatures, up to+600 ° C, and is commonly used for wrapping high-temperature equipment or in insulation layers. Although aluminum foil itself has weak buffering performance, its lightweight and excellent heat reflection properties make it play an important role in some high-temperature environments.

Summary

Choosing the appropriate high-temperature cushion material is crucial for the performance and lifespan of the equipment. By comparing and analyzing these high-temperature cushion materials and their characteristics, we can have a clear understanding of the advantages and limitations of each material. In practical applications, selecting materials reasonably based on specific usage environments, temperature requirements, and performance needs will help improve the overall effectiveness of the cushion and ensure the safe and stable operation of the equipment.
