Rhenofit® D/A

Rhenofit® D/A by Rhein Chemie Additives (Lanxess Group) is a vulcanization activator for polychloroprene rubber. It improves the processing safety of CR-, CSM-, CM- and CIIR-based rubber compounds by raising the critical temperature of basic accelerators. It reduces the tendency of rubber compounds to scorching, while it lowers the necessary activation temperature for acid accelerators. In polymers containing halogen, it acts as an acid acceptor, thereby enhancing aging properties. Rhenofit® D/A increases moduli and in cold-cured fabric proofing, it serves to neutralize traces of acid. It is applied in extruded and injection molded technical articles, bladders, roofing and compounds with chlorinated paraffin, cork and sulfur chloride factice (erasers, swimming caps and rubberized sheets). Recommended dosage level is 3-5 phr and has a shelf life of 1 year.
