Methyl octabromoether, also known as tetrabromobisphenol A-bis (2,3-dibromo (methyl) propyl) ether, is an important variety of brominated flame retardants. It is a high molecular weight organic flame retardant with both aromatic and aliphatic bromine, widely used in XPS extruded boards and EPS foamed polystyrene, and belongs to additive flame retardants. External wall insulation flame retardant, replacing hexabromocyclododecane, with stable product quality and extremely high flame retardant efficiency, can achieve excellent flame retardant effect with minimal dosage, without the need to add other auxiliary flame retardants; Compliant with environmental protection requirements; Compared to traditional flame retardants, it has lower addition costs. Mainly used for XPS extruded board and EPS foamed polystyrene applications with obvious flame retardant effect.

TBC is widely used in polyolefin, PVC, foam polyurethane, polystyrene (PS, XPS), ABS, PP, unsaturated polyester, various synthetic rubbers and synthetic fibers and other products, with compatibility, durability, light resistance, good water resistance and other characteristics. At the same time, it has a good effect in textile flame retardant treatment.

Brominated SBS, also known as brominated styrene butadiene styrene block copolymer, is a new flame retardant that can replace hexabromocyclododecane flame retardant and be applied to foamed polystyrene and extruded polystyrene foam plate. Brominated SBS flame retardant is a stable high molecular weight polymer with high thermal stability and good compatibility with polystyrene materials. It can be shared with synergists in the current EPS/XPS flame retardant system, and is not easy to absorb moisture, which helps to reduce the residual water content of EPS beads and improve production efficiency. Under the same bromine content, the flame retardancy of brominated SBS in polystyrene foam is better than HBCD. The polymer structure makes it not easy to be absorbed by organisms, eliminating environmental concerns.

Melamine cyanurate, also known as melamine cyanurate ester, is a highly efficient, halogen-free, environmentally friendly flame retardant containing nitrogen. It is a white fine powder that has the advantages of economic use, high efficiency, excellent electrical and mechanical properties, no discoloration, low smoke, and low corrosiveness. At the same time, it is low toxic, safe for users, compatible with the environment, and has good thermal stability, making it very suitable for material processing. Characteristics: MCA not only has a good synergistic effect with phosphorus based flame retardants, but also achieves excellent flame retardant effects when used in combination with phenolic compounds. This product has good flame retardant effect, low dosage, non-toxic, low smoke emission, good compatibility with nylon resin, minimal impact on mechanical properties, and is less prone to mold sticking, foaming, and frosting during processing. Usage: Widely used for flame retardancy in rubber, nylon 6, nylon 66, polyurethane, phenolic resin, epoxy resin, polyethylene resin, and acrylic acid.

Mainly suitable for various PP flame retardant materials mainly composed of homopolymer PP and copolymer PP. It is an ideal flame retardant for flame retardant PP products such as European sockets, automotive corrugated pipes, hollow boards, electrical skeletons, automotive connectors, mining PP boards, and heater housings.

Flame retardant masterbatch is made by plasticizing and granulating flame retardant methyl octabromoether on polystyrene as a carrier, with a flame retardant content of 55%. It not only has excellent flame retardant properties of methyl octabromoether powder products, but also has advantages such as good dispersibility, low addition amount, easy foaming, easy extrusion, stable production, and environmental protection. Suitable for various extrusion board production equipment, with neat and uniform particle shape, no dust, and no pollution to equipment and the environment. This product is used as a flame retardant for extruded polystyrene (XPS).
