Amorphous ethylene-propylene rubber with medium ENB (ethylidene norbornene) content and a medium Mooney viscosity.
The polymer structure of this product is characterized 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.
