Magnesium Oxide Boosts Flame Retardancy in Rubber Compounds
polymer additives
The rubber industry is increasingly adopting magnesium oxide as a critical additive for improving flame retardancy. With stringent global safety regulations, manufacturers seek solutions that combine performance with compliance. Magnesium oxide, especially high-purity grades from sources like China’s magnesia capital, offers excellent thermal stability and smoke suppression in rubber compounds.

In addition to flame retardancy, fillers like calcium carbonate remain essential for enhancing tensile strength and reducing costs. Meanwhile, titanium dioxide continues to dominate as a key pigment for UV resistance and coloration in plastics. The synergy between these additives allows for versatile rubber and plastic formulations.

Market trends indicate rising demand for eco-friendly additives. Magnesium oxide, derived from natural magnesite, aligns with green manufacturing initiatives. Its role in rubber compounding extends to improving vulcanization efficiency and product longevity, making it a preferred choice for automotive and construction sectors.
