Vulcanizing agent 2,5-Dimethyl-2,5-di(tert-butylperoxy)hexane CAS 78-63-7
It serves as a cross‑linking agent for silicone rubber, polyurethane rubber, ethylene‑propylene rubber and other rubbers. It can also be used as a cross‑linking agent for polyethylene and a vulcanizing agent for unsaturated polyesters.
This product avoids the drawbacks of di‑tert‑butyl peroxide (easy volatilization) and dicumyl peroxide (unpleasant odour). It is an effective high‑temperature vulcanizing agent for vinyl silicone rubber. The finished articles feature good tensile strength and low elongation.
