抗静电 Celcon® POM 美国塞拉尼斯 CF802 耐燃油 通用级 聚甲醛
抗静电 Celcon® POM 美国塞拉尼斯 CF802 耐燃油 通用级 聚甲醛
Acetal (POM) Copolymer
Celanese Corporation
产品说明:
Celcon® acetal copolymer grade CF802 is a conductive, fuel compatible general purpose acetal copolymer. Celcon® CF802 has been developed to dissipate static electricity from fuel handling systems.
Please note Celcon® CF802 has special processing considerations to ensure static dissipation properties. Use minimum back pressure and slowest screw speed possible in retracting screw during cooling portion of cycle. Large gate size (>2 mm) recommended. Pneumatic conveying of material long distances is not recommended.
