RUBBER & ELASTOMERS

Zinc oxide is an essential material in rubber vulcanization systems, functioning as a vulcanization activator in sulfur curing processes. It contributes to cross-link density, processing stability and the mechanical performance of rubber compounds. Application-specific surface area (BET) and controlled particle characteristics support predictable curing behavior, efficient compound processing and durable elastomer performance.

Key Requirements

Application-Specific Surface Area (BET)

The specific surface area of zinc oxide influences its interaction with curing systems and rubber compounds. Controlled BET supports predictable curing behavior and balanced compound processing.

Stable Particle Size Distribution

Uniform particle size distribution enables efficient dispersion within rubber compounds, improving compound homogeneity and mechanical performance.

Controlled Reactivity in Vulcanization

ZnO acts as an activator in sulfur curing systems. Controlled reactivity ensures predictable vulcanization behavior and consistent cross-link formation.

Consistent Quality for Compound Processing

Rubber production requires stable material quality to ensure consistent compound formulation, predictable processing behavior and reproducible final properties.

Typical Properties

High-purity zinc oxide (typically 97–99.9% ZnO) with controlled low and medium BET grades supports predictable curing activation, stable compound processing and reproducible mechanical properties in rubber and elastomer systems.
