| Product Description: Akrosperse DDPH-50/EPR/S is a 50% active dispersion of liquid dialkyl peroxide in Ethylene Propylene co-polymer binder for use as a cross-linking agent in synthetic and natural rubbers. Chemically, DDPH is 2,5-Dimethyl-2,5-Di-(t-butylperoxy) hexane. Note: The actual percent active peroxide is 45-46. This is because the pure liquid peroxide is approx. 92% active. The pure product is always cut for safer handling. Applications: In it’s pureform, Akrochem® DDPH peroxide is a colorless, low odor catalyst used for cross-linking a variety of synthetic rubbers including EPR, EPDM, EVA, NBR, Polychloroprene, PVC, Chlorosulphonated Polyethylene, SBR, Polyurethane, and Silicone. Typical dosages range from 1.0 to 10.0 phr depending on polymer type and filler loadings. In its liquid form, DDPH can be used as a cure catalyst in applications where optical clarity is essential. DDPH will not bloom from EPDM's. Advantages: Polymer bound or encapsulated dispersions are a proven means of upgrading plant safety, efficiency, quality & raw material control. Akrochem polymer bound or encapsulated chemical dispersions eliminate any irritating dust, as well as other potential hazards in handling powders in the plant. The physical form is easy to handle and weigh accurately. With a dispersion, better uniformity of the mix at lower processing temperatures is possible. Information provided by Akrochem Corporation |
