hostaform pom C 27021 TF
 
HOSTAFORM C 27021 TF | POM | Tribological
 
Description
Hostaform® C 27021 TF is an injection molding type, modified with PTFE; good chemical resistance to solvents, fuel and strong alkalis as well as good hydrolysis resistance; high resistance to thermal and oxidative degradation; for sliding combinations with very low coefficient of friction. High viscosity
 
Other Processing
Injection Molding
Standard injection moulding machines with three phase (15 to 25 D) plasticating screws will fit.
