Cooperation Content: The key pain point was that traditional flame retardants reduced transparency in PC/ABS materials and failed to meet halogen-free RoHS and REACH requirements. We recommended the new polymeric phosphate flame retardant (RDP) and sent technical experts for a two-week on-site training and optimization. This product uses high-molecular polymerization technology to ensure no impact on optical properties (transmittance >90%) while enhancing heat resistance and mechanical strength. We also provided compatibility test reports to help adjust injection molding parameters.  Results: Post-implementation, the flame retardancy reached UL94 V-0 level and passed stringent JIS testing in Japan. The material’s appearance remained pristine, avoiding previous hazing issues, enabling successful exports to Japan with a 30% increase in annual volume. The client noted a 5% reduction in scrap rates, securing long-term contracts with major clients like Sony, and growing cooperation value from $500,000 initially to over $2 million annually.
