Keltan® 5470C
Highly crystalline ethylene-propylene rubber with medium ENB (ethylidene norbornene) content and a medium Mooney viscosity. The combination of high crystallinity, narrow molecular weight distribution and medium viscosity provides an extremely robust polymer with good processing characteristics. Due to the high crystallinity of the grade very high mechanical strength can be achieved.
