Keltan® 2650C

Keltan® 2650C

Amorphous ethylene-propylene rubber with medium-high ENB (ethylidene norbornene) content and a low Mooney viscosity. The amorphous structure ensures very good low temperature properties. The combination of the very low Mooney viscosity and Controlled Long Chain Branching result in excellent curing and processing characteristics. Main application areas for this grade are potable water seals and high hardness applications.
