The red phosphorus microcapsules flame retardant agent, which we product, is halogen-free, add type and environmental friendly. Its surface with an oxide or hydroxide through the unique "ultrafine and stabilization modification" process, the ultra-fine red phosphorus with an inorganic compound and an organic resin composite coating so isolated, so its easy toovercome burning, hygroscopic characteristics. Advantage: not easy to moisture absorption and be oxidized, not easy to cause dust explosion, high impact, no poisonous gas etc. Dispersion, physical and mechanical properties, thermal stability and flame retardancy are significantly increased and improved.
