Magnesium Oxide as an Acid Acceptor in Rubber Compounding

Magnesium Oxide as an Acid Acceptor in Rubber Compounding

Thermoset elastomers are vulcanized (cured) to produce a degree of crosslinking between polymer chains. Magnesium oxide impacts the vulcanization process. The key to successful rubber and plastics compounding is the accurate timing of activity – the property that regulates the rate at which magnesium oxide accepts acidic by-products. Scrupulously manufactured to precise specifications in size, surface area, porosity and dispersion characteristics, Elastomag^® magnesium oxide functions as an acid acceptor and eliminates unnecessary cycle changes, reduces stock losses, and helps maintain control over product consistency. Consistent compounding times ensure accurate reproducibility with each production run. Elastomag's precision means maximum predictability on the manufacturing floor by way of repeatable cure rates. Elastomag^® magnesium oxides are used in rubber/halogenated elastomers, polychloroprene/phenolic resin adhesives, and polyester sheet molding compounds.
