Activating Rubber Industry With SUPERMAG – High-Performance Magnesium Oxide

Posted by

High-active Magnesium oxide is used both as a curative for chloroprene compounds and as an acid acceptor in halogenated polymer systems. Chloroprene Rubber (Neoprene), improves processibility, cure rate, and vulcanization. In general, the higher the activation of Magnesium Oxide, the greater the processing safety and the better the vulcanization properties. In Fluoroelastomers, it acts as an acid acceptor as they serve to neutralize hydrogen fluoride generated during the cure or on extended aging at high temperatures.

If exposed to atmospheric moisture and carbon dioxide, even briefly, Magnesium Oxide gets converted to Magnesium Hydroxide and Magnesium Carbonate thereby losing its activity by a substantial degree. Therefore, it is imperative to protect this product from inevitable atmospheric reactions until it is added to the compound.

Considering all these aspects our Research & Developmental team has improvised a specially surface-treated high-active Magnesium Oxide, namely Supermag 150 which acts as a superior vulcanizing agent in Chloroprene rubber, and Synthetics Rubber (FKM, CIIR, BIIR, CPE). Supermag 150 being a specially surface-treated product exhibits superior compatibility, excellent dispersibility, improved moisture resistance, and also adhesion resistance on the mixing roller.
