Applications/Examples of results

- Semiconductor manufacturing equipment (wafer/glass holding parts for etching equipment) - Vacuum environment components (sliding parts within vacuum chambers: SCM7000HP) - Glass transport system (transport parts requiring wear resistance) - High-temperature sliding parts (bearings and bushes that can withstand temperature ranges that other resins cannot) - Insulation parts (thermal insulation materials that utilize low thermal conductivity) 【Selection】For applications that require a vacuum or clean environment and want to avoid metal contamination, use SCM7000HP; for other high-temperature and wear-resistant applications, SCM7000 is the basic choice. 【Note】PBI is an expensive material. For applications that can be satisfied at temperatures below 260°C, PEEK is a more practical option.

Detailed information

• 

  SCM7000 (Black) PBI Standard Grade This is the basic grade of PBI. It is a machining material that possesses the fundamental properties of PBI: high heat resistance, low thermal expansion, low thermal conductivity, high strength, and high hardness. Suitable for sliding parts at high temperatures, wear-resistant parts, and insulating parts. Round bars φ11 to φ50.

• 

  SCM7000HP (Black) PBI High Purity Grade This is a high purity grade with low metal content, suppressing impurities and outgassing, intended for use in vacuum chambers. It is suitable for vacuum components in semiconductor manufacturing equipment and wafer/glass holding parts. Round rods φ11 to φ50.
