This grade of HBCD(Grade B)is mainly uses in those thermoplasticity and thermoset high molecular polymer which have flame-resistant request. Especially suitable for the oil paint and the textile coating. 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 as the great heat stability, low addition level, and do not need to add other assistant flame retardant(Such as antimony oxide). Its especially used in textiles well!!!
