Keltan® 4577
Crystalline ethylene-propylene rubber with medium ENB (ethylidene norbornene) content and a medium Mooney viscosity at 75 PHR extender oil. The combination of very high molecular weight and high green strength results in a very high level of physical properties and contributes to an excellent collapse resistance in extruded profiles.
