Description


What is PI (Polyimide)?

 
PI Polyimide Vespel is a high-temperature engineering polymers originally developed by the DuPont™ Company. It is a non-melting high temperature polymer, it remains its high strength, dimensional stability, and creep resistance even at temperatures above 260°C. Polyimide exhibits an exceptional combination of thermal stability, mechanical toughness, and chemical resistance. They have excellent dielectric properties and inherently low coefficient of thermal expansion. Another advantage inherent in polyimide is high resistance to hydrolysis. Polyimide has excellent resistance to a broad range of chemicals, however, it will be attacked by 10% and stronger solutions of sodium hydroxide.
 

Characteristics:

 
- Non melting high temperature polyimide
- Long term thermal stability 300°C (short term up to 400 °C)
- High heat resistance up to 470 °C (HDT/A)
- Good cryogenic properties down to -270 °C
- High strength, modulus and stiffness also at high temperatures over 260 °C
- Excellent thermal and electrical insulation
- High purity, low outgassing in vacuum conditions
- Good machinability
- Inherently flame retardant
