Import Brominated Sbs — Buy in wholesale FOB from Supplier in China

Weifang Yukai Chemical Co., Ltd. supplies Br-SBS (CAS 1195978-93-8), a brominated polymeric flame retardant positioned as a direct HBCD replacement for expanded and extruded polystyrene foam systems. The material is an oligomeric brominated styrene-butadiene-styrene copolymer with comparable bromine content to hexabromocyclododecane, formulated to deliver equivalent flame retardant performance in EPS and XPS applications without major reformulation. The supplier packs this product in 25 kg paper bags, 40 bags per pallet, with jumbo bag options available, achieving 20 metric tonnes per 20-foot container.

The polymeric architecture of Br-SBS confers thermal stability during polystyrene foam processing, resisting degradation at typical extrusion and expansion temperatures. Its high molecular weight oligomer structure reduces volatility and leaching compared with smaller-molecule brominated flame retardants, while maintaining melt flow properties compatible with standard polystyrene foam extrusion lines. UV resistance is inherent to the polymer backbone, an advantage for insulation boards exposed to daylight during construction. The product functions through gas-phase radical quenching, releasing bromine species at decomposition temperatures that interrupt combustion chain reactions.

Primary applications span construction insulation boards, cold-chain packaging foams, and geofoam applications where HBCD phase-out compliance is mandated. Buyers include EPS/XPS foam manufacturers, building materials distributors, and insulation systems integrators in Europe, North America, and East Asia. The supplier operates from Lingang Industry Park in Binhai Development Zone, Weifang, Shandong Province. Prospective importers should verify bromine content, melt flow index compatibility with their base resin, and regulatory acceptance in their destination market before committing to volume orders.

Weifang Yukai Chemical Co., Ltd. is located at Lingang Industry Park, Binhai Development Zone, Weifang 262737, Shandong Province, China. The supplier holds a Harbor trust tier designation on the platform, with a recorded response rate of 0.00 percent and an average response time of zero hours, indicating no response data is currently logged in the system. The company profile does not disclose establishment year, workforce size, revenue figures, or named client relationships.

The listing presents Br-SBS as its core product, emphasizing HBCD replacement with minimal reformulation burden for existing polystyrene foam production lines. No ISO certifications, third-party audit statements, or patent references appear in the available profile data. The supplier's address places it within a concentrated chemical manufacturing corridor in northern Shandong, near Weifang Port facilities. Buyers should conduct direct due diligence on production capacity, quality management systems, and export licensing status before reliance on this source.
