(lithopone for rubber)
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.
Compared to titanium dioxide or calcium carbonate fillers, lithopone demonstrates:
Parameter | Chinese Producers | European Suppliers | US Manufacturers |
---|---|---|---|
ZnS Purity | 29.5% ±0.3 | 28.9% ±0.5 | 29.1% ±0.4 |
Moisture Content | 0.12% max | 0.18% max | 0.15% max |
Annual Capacity | 120,000 MT | 45,000 MT | 38,000 MT |

A 2023 case study with a conveyor belt producer showed:
Major Chinese lithopone suppliers maintain:
Recent R&D breakthroughs include nano-structured lithopone (80-110 nm particles) demonstrating 40% better reinforcement at equal loading rates. The global lithopone market for rubber applications is projected to reach $720 million by 2028, driven by demand from the automotive and industrial sectors.
(lithopone for rubber)
A: Lithopone for rubber is a white pigment blend of zinc sulfide and barium sulfate. It enhances rubber products' opacity, durability, and UV resistance. It's widely used in tires, hoses, and industrial rubber goods.
A: Wholesale suppliers offer bulk pricing, ensuring cost-efficiency for large-scale rubber manufacturing. They often provide customized particle sizes and purity levels. Reliable suppliers also ensure timely delivery and technical support.
A: Look for ISO-certified manufacturers with proven expertise in rubber-grade lithopone. Check for quality certifications, production capacity, and customer reviews. Established manufacturers often provide samples for testing.
A: China-based producers dominate with cost-effective pricing and advanced production technology. They adhere to international standards like REACH and RoHS. Many offer export-friendly services, including logistics and documentation support.
A: Yes, lithopone enhances rubber's resistance to weathering, abrasion, and oxidation. This extends the lifespan of rubber products in harsh environments. Its fine dispersion also ensures uniform color and texture.
