Dutral® TER 4437 is an Ethylene — Propylene — Diene polymer produced by suspension polymerisation using a Ziegler—Natta Catalyst at the Ferrara production facility in Italy.

A non—staining antioxidant is added during the production process.

Key Features
Dutral® 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.

Dutral® TER 4437 W0 is a very high molecular weight terpolymer of medium diene content, extended with 40% paraffinic oil.

Thanks to the pure paraffinic oil Dutral® TER 4437 WO 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.
