Reactive blending, reinforcement and curing of NR/BR/EPDM
Incorporation of EPDM into NR/BR blends improves ozone resistance, but leads to poor properties because of differences in filler affinity and cure incompatibility of the rubber components. In this work, the cure incompatibility is overcome by utilising a reactive processing technique, making use of the most commonly used accelerator CBS and sulfur.

Reactive Blending, Reinforcement and Curing of NR/BR/EPDM
In this work, the cure incompatibility is overcome by utilizing a reactive processing technique, making use of the most commonly used accelerator CBS and sulfur. The entire amount of curatives is first added into the EPDM. After a thermal pretreatment step related to the scorch time of the EPDM, the modified EPDM is mixed with pre-blended NR/BR.

EPDM-rubber in blends with NR/BR-elastomers for ozone
N2 - Blending of saturated ethylene-propylene-diene rubber (EPDM) with highly unsaturated rubbers, such as natural rubber (NR) and (butadiene rubber) BR, is a rapidly developing area especially for tyre sidewall applications, where the saturated elastomer can be considered as a polymeric antioxidant for the diene rubbers.

Development of a Passenger-Car Radial-Tyre Sidewall
arising out of the direct mixing of an NR/BR/EPDM blend. With incorporation of pretreated EPDM in an NR/BR blend, it was possible to reduce antidegradant and wax dosages, with improvement in ozone resistance, fatigue to failure, and cut growth properties.
