Rubber

Introduction

Rubber pigment powder is engineered for elastomer coloration under extreme mechanical and environmental conditions. These organic formulations withstand vulcanization temperatures up to 180°C (ASTM D3182) while maintaining ≤0.7ΔE color stability. With 99% particle fineness below 3μm (ISO 13320), the powder ensures homogeneous dispersion in natural and synthetic rubbers without affecting tensile strength (±5% vs uncolored control per ASTM D412).

The colorants resist sulfur blooming and ozone degradation (≤0.5% surface bloom after 1,000 hours ASTM D1149). Produced at 700 metric tons monthly, our pigment delivers ≤1.8% batch variance for automotive, industrial, and medical rubber goods. Specialized dispersion aids prevent scorching during mixing, reducing Mooney viscosity variation to ±3 points (ASTM D1646).

Technical Advantages
50% lower compression set vs standard pigments
Resistance to oil/fuel extraction (ASTM D471)
0.02% weight loss at 150°C aging (ASTM D573)
Compatible with peroxide/EVE cure systems

Applications
Automotive: Tire sidewall markings, engine seals, hoses.
Industrial: Vibration damping mounts, conveyor belts.
Medical: Sealing components, rubber stoppers.
Consumer Products: Rubber grips, elastic bands.
