PEEK
What is PEEK?
PEEK, polyetheretherketone, is a crystalline high temperature thermoplastic which offers excellent thermal and chemical resistance properties and outstanding resistance to abrasion and dynamic fatigue. It is recommended for electrical components where a combination of high continuous service temperature (480 degrees) with very low emission of smoke and toxic fumes on exposure to a flame is required.
PEEK meets UL 94 V-0 requirements at 2 mm or 0.080″. This product is extremely resistant to gamma radiation, even exceeding that of polystyrene. The only common solvent that will attack PEEK is concentrated sulfuric acid. Hydrolysis resistance of PEEK is exceptional and it can operate in steam up to 500 degrees F.
