MICRO-ENCAPSULATED RED PHOSPHORUSSERIES FLAME RETARDANT
Microencapsulated red phosphorus fame retardant series ishalogen-free fame retardant, with red phosphorus as the core material, fame retardant with high thermal stability and itcoefficant as the capsule material, using the microencapsulatiorprocess with independent intel- lectual property rights to obtain cseries of products with very low fneness, very narrow particle sizedistribution and hiah stability, On the basis of retaining the overaadvantage of common red phosphorus as fame retardant, thethermal stability of the product is greatly improved, and theco-effect of core material and capsule material on fame retardancan be played.After microencapsulation, the product has certaircolor extinction and particle size microrefinement, which makes theproduct have good compatibility with the polymer, and the thermdstability and security are qreatly improved, which is convenient fostorage, transportation and processing.
Because the surface of red phosphorus is wrapped in a capsule, the exposure rate of red phosphorus in the air is reduced, and the amount of phosphine produced by red phosphate rancidation is further reduced, thus greatly reducing the risk of polymer material processing. At the same time, the ignition temperature of red phosphorus flame retardant was increased. Due to the introduction of the pouch flame retardant system, this series of flame retardants has the characteristics of expansion flame retardants. This series is a kind of efficient flame retardants, and less amount can achieve good flame retardant effect. Due to the small amount of addition, it has less impact on the mechanical and electrical properties of the polymer material, and can greatly improve the leakage trace index of the polymer material. At the same time, this series of flame retardants also has a smoke suppression effect, this product is environmentally friendly and halo- gen-free, in line with the requirements of the latest EU ROHS directive, in line with the REACH regulation certification, and through SGS testing.

Scope of application
Mainly used in oxygen-containing high polymer polyamide (also known as nylon), polyester (commonly known as polyester), polyurethane, polyisocyanurate, epoxy resin, glass fiber reinforced polyurethane flame retardant. It can also be used as a flame retardant synergist in polymers that do not contain oxygen such as polyolefin and polystyrene. Widely used in electronic and electrical nylon or glass fiber rein- forced plastic parts, wire and cable, model plastics, epoxy resin, synthetic glue, closed cell foamed plastics, automotive interior fibers, etc.
