Flame retardant products, non-halogen flame retardant microencapsulated red phosphorus, with its superior overall performance, more and more users are optimistic.

Red phosphorus is a good flame retardant, with less added, the advantages of a wide range of uses. Generally red phosphorus easy to absorb moisture, and polymer materials, poor compatibility, can not actually use. I plant the use of international advanced multi-layer microcapsule coating process, select the special capsule material, through the inorganic - organic multilayer continuous coating system of microencapsulated red phosphorus flame retardant, reducing the activity of red phosphorus to solve Compatibility, and maintain a high content of effective flame retardant ingredients. The flame retardant has excellent flame retardancy and physical properties.

This product is mainly used in thermoplastic resin such as PET, PA, PA, PE, EVA, vinyl acetate copolymer, cable material, Oxygen, phenolic, unsaturated polyester and other thermosetting resins, as well as butadiene rubber, ethylene propylene rubber, fabric flame retardant.

Microencapsulated red phosphorus flame retardant core of the core system after grinding high-grade red phosphorus particles, capsule shell itself also has flame-retardant properties of organic and inorganic composites.
