[Beite Chemical] Advantages and uses of bromotriazine as a new flame retardant

Bromotriazine is in the form of white powder with a white appearance, large molecular weight, complex structure, good thermal stability and electrical properties, and excellent light resistance. Brominated triazine is different from traditional brominated flame retardants in that it has a high initial decomposition temperature. At the same time, due to its flame retardant mechanism, it has an endothermic decomposition and thermal degradation type and does not contain free bromine.

Bromotriazine flame retardant is a new type of flame retardant with bromine/nitrogen synergy. It has excellent resistance to UV radiation and light resistance, overcoming the poor light resistance and color of tetrabromide and decabromide. The disadvantage of yellowing is that it is an upgraded product of tetrabromide and decabromide. However, traditional brominated flame retardants will produce free bromine, which can avoid the adverse effects of free bromine on production equipment and the natural environment, making the production equipment more reliable and having better product characteristics. It is especially suitable for most flame retardants such as ABS. , PBT, Pc/abs, HIPS and other plastic products produced at higher temperatures. In addition, due to the synergistic effect of bromine and nitrogen flame retardants, its flame retardancy is better than tetrabromide and decabromide.

The uses of bromotriazine are as follows:

Bromotriazine is specially developed for flame retardant ABS, PBT, PC/ABS, HIPS, etc. New products generally need to add Sb2O3 antimony trioxide during use. Engineering plastics containing given products can be used in various injection molding and extrusion situations, can meet various processing requirements, and can smoothly recycle and process flame-retardant recycled materials.

Mainly used as flame retardant in ABS, PS, HIPS, PC, PBT, PET, PE, PVC; used in HIPS, PBT, ABS, PS, GF+ABS, GF+PBT, GF + Flame retardant modification in fields such as PS, which has high thermal stability, UV resistance, migration resistance, and notch impact strength. It needs to be synergized with Sb2O3.

PS: Brominated triazine flame retardants have adverse effects on the mechanical properties of engineering plastics, and engineering plastics added with brominated triazine also have corresponding adverse effects on the mechanical properties. However, due to its large molecular structure, melting point closer to the production temperature of engineering plastics, good compatibility, and better mechanical properties of flame-retardant products, the damage to the mechanical properties and process properties of engineering plastics is significantly lower than that of tetrabromide and decabromide. However, the production temperature is difficult to exceed 300°C to prevent the gas from causing flame retardants and adversely affecting the surface and mechanical properties of the plastic. Bromotriazine can be applied directly without pre-drying, and the added plastic can be continuously extruded and injected without discoloration or other side effects.
