Diene content and cure rate of Buna® EP

The range of Buna® EP grades comprises both copolymers and terpolymers. Copolymers can only be crosslinked with peroxides or radiation. Terpolymers can be crosslinked both with peroxides and with sulfur. The cure rate and the crosslink density increase with increasing diene content.

Terpolymers with high levels of ENB are particularly suitable for the production of profiles by pressure-less continuous vulcanization, or for co-vulcanization with diene rubbers.
