VICTREX? PEEK POLYMER 90G
High performance thermoplastic material, unreinforced PolyEtherEtherKetone (PEEK), semi crystalline, depth filtered granules for injection moulding, very easy flow, colour natural/beige.
Complex geometries with thinner cross sections or longer flow lengths, for high strength and stiffness as well as good ductility. Chemically resistant to aggressive environments, suitable for sterilization for medical and food contact applications.
