Keltan® 8550C

Amorphous ethylene-propylene rubber with medium ENB (ethylidene norbornene) content and a high Mooney viscosity. The high molecular weight and branched structure ensure fast mixing and efficient vulcanization. The high level of Controlled Long Chain Branching facilitates the extrusion of the most intricately designed profiles. This grade is broadly applicable. Examples are dense profiles and coolant hoses.
