Keltan® 4450S

Amorphous ethylene-propylene rubber with medium ENB (ethylidene nornomene) content and a medium Mooney viscosity. The polymer strucutre of this product is charactereized by a broader molecular weight distribution in combination with a higher level of Controlled Long Chain Branching compared to the Keltan 4450. The structure ensures superior mixing and milling behavior, fast filler incorporation and high extrusion speeds. Typical applications for this product are automotive solid profiles and molded goods.
