KEPITAL® TE-21

KEPITAL® TE-21 by KEP is an impact-modified, toughened, medium-viscosity polyoxymethylene (POM) grade. Offers excellent thermal stability and stronger resistance to alkalis than acetal homopolymer. Possesses wide range of working temperature, good impact strength, good surface and high tolerance to organic chemicals. Exhibits fatigue-, creep resistance, noise reduction and better flow enabling high speed production. Shows resistance to friction and wear. Is suitable for processing by injection molding. Used in electrical & electronics, automotive and industrial parts. KEPITAL® TE-21 is a RoHS-compliant grade.
