Product description:
Product usage:
It is a reactive flame retardant, a polyester resin, flame-retardant epoxy resin can be used, also can be used as a flame retardant for PS, PP, PE, ABS resin, flame retardant, can be used for the synthesis of fine chemicals.
Product performance:
This product contains a high amount of bromine, add less, good flame-retardant effect, the degree of unsaturation of the ointment that high crosslink density, light, good thermal stability and excellent weather resistance, having an antistatic effect. Added in the resin does not affect its quality (such as mechanical properties, electrical insulation properties). Low toxicity, do not pollute the environment. This product has a wide range of applications, either as a the ideal reactive flame retardant but also as additive flame retardant.
Solubility: insoluble in water and aliphatic hydrocarbon solvents, can be dissolved in nitrobenzene, N, N-dimethyl formamide, slightly soluble in acetone, xylene, chlorinated hydrocarbon solvents, dioxane.
