Product Description
POM copolymer

Antistatical modified very easy 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 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 Ticona's ESD (electrostatic dissipative) grades for those applications
