Hostaform® C 9021 AS
POM(聚甲醛)
塞拉尼斯(Celanese)
产品描述
Antistatic grade
POM copolymer Antistatical modified; standard flowing Injection molding type; the antistatical effect improves, when the molding part absorbs enough humidity; good chemical resistance to solvents, fuel and strong alkalis as well as good hydrolysis resistance; high resistance to thermal and oxidative degradation. Hostaform C 9021 AS is suggested for dissipation of minor buildup of static electricity that might occur with standard type grades. However, it is not intended for use in fuel system components where static dissipation is critical to part performance. Please refer to Celanese's ESD (electrostatic dissipative) grades for those applications Preliminary Datasheet
