Rubber and plastics

Iron oxide (especially red iron oxide) plays a dual role in the rubber and plastics industry: inorganic pigment and functional filler.

Tinting: Providing stable, weather-resistant red/reddish-brown tones.

Reinforcement and modification: improving the heat resistance, aging resistance, and electrical insulation properties of rubber/plastics.

In the rubber and plastics industry, iron oxide is not simply used for "adding color"—it's both a visual enhancer and a performance booster

By carefully controlling purity, particle size, pH, and dispersibility, it is possible to maintain color while simultaneously improving the durability, safety, and added value of the product.。
