KOCETAL® GB704

Technical Datasheet | Supplied by Kolon ENP

KOCETAL® GB704 by Kolon ENP is a polyacetal polyoxymethylene copolymer grade reinforced with (<25)% glass bead. Possesses good toughness, moldability, dimensional and thermal stability. Exhibits low warpage, high crystallinity and does not deflect over the heat deflection temperature. Provides heat-, friction and wear resistance. Is resistant to gasoline, lubricant and alkali. Shows lower mechanical stiffness than homopolymers. Is suitable for processing by injection molding. KOCETAL® GB704 by Kolon ENP is used in gears, roller, cars, office equipment and living materials. by Kolon Plastics (Kolon Industries) complies with ISO 9001, ISO/TS 16949, ISO 14001 and KS I 7001/7002 certificates.
