KOCETAL® CB301
Technical Datasheet | Supplied by Kolon Plastics (Kolon Industries)
KOCETAL® CB301 by Kolon Plastics (Kolon Industries) is a medium viscosity polyacetal polyoxymethylene copolymer grade reinforced with carbon black. Provides high mechanical strength, good dimensional stability, moldability and durability. Exhibits high heat-, friction-, wear and chemical resistance. Possesses high rigidity & crystallinity, good toughness, thermal stability and electrical conductivity. Shows less change in mechanical properties than nylon and PBT over 50-80°C temperature. Is suitable for processing by injection molding. Used in gears, roller, cars, office equipment and living materials. KOCETAL® CB301 is recommended for automotive, electrical, electronic, agriculture, building and construction industries. Complies with ISO 9001, ISO/TS 16949, ISO 14001 and KS I 7001/7002 certificates.
