Rhenofit D/A
Highly reactive magnesium oxide
Rhein Chemie Corporation
ï

Sp.gr. 3.60; white powder

A highly reactive magnesium oxide intended specifically for use in the rubber processing industry; improves the processing safety of CR, CSM, CM and CIIR based rubber compounds by increasing the critical temperature of basic accelerators; reduces the susceptibility of rubber compounds to scorching; In acid accelerators, it lowers the necessary activation temperature; in polymers containing halogen, and particularly in CR, it acts as an acid acceptor, thereby improving aging properties; in cold-cured fabric proofing, it serves to neutralize traces of acid; moduli are generally increased by Rhenofit D/A.
