EPDM
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.
Typical applications are in automotive profiles, TPV and (low hardness) moulded goods.
