Lithopone for Rubber: The Foundation of Durable Elastomers

Lithopone (ZnS·BaSO₄) serves as a critical reinforcing agent in rubber production, with 78% of high-grade rubber formulations containing this composite pigment. Its unique zinc sulfide/barium sulfate matrix (typically 29-30% ZnS content) enhances vulcanization efficiency while maintaining cost-effectiveness. Major tire manufacturers report 15-20% improvement in abrasion resistance when using lithopone versus conventional fillers.

Technical Superiority in Modern Rubber Engineering

Compared to titanium dioxide or calcium carbonate fillers, lithopone demonstrates:

• 18% higher UV resistance in outdoor rubber applications
• 0.32-0.38 g/cm³ optimized density for even dispersion
• pH stability between 6.8-7.2 across temperature extremes (-40°C to 120°C)
