Rhenofit 2120
Active magnesium oxide
Rhein Chemie Corporation
ï

Sp.gr. 3.57; white powder

An active magnesium oxide especially selected for the use in the rubber processing industry; improves the processing safety of rubber compounds based on CR, CSM, CM and CIIR; raises the critical temperature of basic accelerators and thus prevents scorching; In acid accelerators, the activiting temperature of acid accelerators is decreased; in polymers containing chlorine, especially CR, it serves as an acid acceptor and thus improves the aging properties of the vulcanizates; in cold cured rubber coated fabrics, Rhenofit 2120 is used to neutralize acid traces; moduli are generally increased by its addition.
