Hexabromocyclododecane FR 4075A grade

Detailed Product Description
Product Description
FR 4075A is mainly uses in those thermoplasticity and thermoset high molecular polymer which have flame-resistant request. The product has great quality when uses in polystyrene foam(EPS), the oxygen index(OI) may higher than 30 and reaches the stated self extinguishing standard. Meanwhile the product also has many advantages for other polymer systems, such the great heat stability, low addition level, and do not need to add other assistant flame retardant(Such as antimony oxide), especially the big size is very suitable for some HIPS user, big size brings perfect flowing in production, particle size is 0.2~0.6mm.
