Hostaform® C 27021 AS
聚甲醛（POM）共聚物
Celanese Corporation
產品說明:
POM copolymer
Antistatical modified; very easy flowing Injection molding type; the
antistatical effect improves, when the molded 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 27021 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
