Zinc Oxide as an Essential Activator in Rubber Compounding

Zinc Oxide is one of the most important activators used in sulphur vulcanization systems. It works together with accelerators to improve curing efficiency and promote strong crosslink formation within rubber compounds. Without sufficient activator activity, vulcanization may be slow or incomplete, leading to poor physical properties.

Zinc Oxide improves accelerator solubility and reaction rate, resulting in faster curing and better crosslink density. It also contributes to improved tensile strength, abrasion resistance, and ageing properties of rubber compounds.

Consistent-quality Zinc Oxide supports predictable curing behavior and stable compound performance. It is widely used in tyres, tubes, footwear, molded goods, hoses, belts, and automotive rubber parts. Reliable Zinc Oxide supply helps manufacturers maintain uniform product quality and reduce processing variations.
