Key Features
Elastomers are characterized by excellent resistance to ageing and weathering, good resistance to both high and low temperatures, low permanent set values, good resistance to a large number of chemicals.
Ethylene Propylene Diene Rubber 4437 is a very high molecular weight terpolymer of medium diene content, extended with 40% paraffinic oil.
Thanks to the pure paraffinic oil Ethylene Propylene Diene Rubber 4437 can be advantageously used in TPV.
It is characterized by high loading capacity, easier dispersion of ingredients during mixing, good dimensional stability and low temperature elasticity.
Main Applications
Automotive, mechanical goods, appliances, TPV.
Physical Form
