Heat Resistance, Flame Resistance and Chemical Resistance
PEEK is a crystalline plastic with properties that have not been conventionally available; it has high heat resistance (continuous use temperature of 260°C), as well as superior chemical resistance and hot water resistance. It is also a plastic with high flame resistance and extremely low generation of smoke and corrosive gases upon combustion.
Uses:
The primary uses for PEEK are as semiconductor/liquid crystal manufacturing equipment components, testing equipment components, medical equipment components and the like.
Characteristics:
- PEEK has superior resistance to hot water, and can be used continuously in steam at 200 to 260°C. It can withstand a temperature of 300°C for short periods of time, and among plastics, it has the highest resistance to hot water.
- PEEK has superior chemical resistance, and extremely superior resistance to acids and bases under high temperatures. It is, however, affected by concentrated sulfuric acid.
- PEEK has a high continuous use temperature of 260◦C, but because its glass transition temperature is low at 143◦C, it requires care when being used under high temperatures and high loads.
- PEEK is a plastic with high flame resistance, with minimal generation of smoke and toxic gases upon combustion.
- The recommended grades for high sliding wear resistance are PEEK (NC), PEEK 430-AE3, PEEK 4000 and PEEK 4110.
