Product introduction
BC - 58 is a kind of brominated aromatic flame retardant, which is mainly used in thermoplastic plastics. It is very suitable for the processing of engineering plastics with high requirements for thermal stability, UV stability and color.
Because BC - 58 has unique comprehensive properties, it is especially suitable for processing PBT, PET, PBT/PET blend resins, polycarbonate, ABS, PC/ABS, polysulfone resin, SAN and various laminating resins. The UV stability of BC - 58 makes it able to meet the formula requirements for Indoor Fluorescent irradiation and outdoor sunlight exposure. In addition, the high purity of BC - 58 ensures excellent electrical and thermal stability.

Product application guide
Environmental protection high performance flame retardant PBT:
Both BC - 52 and BC - 58 can be used for both enhanced and non enhanced PBT resins. The four brominated bisphenol A apparatus can effectively maintain the well known color, strength, melt fluidity and thermal stability of PBT. BC - 58 can provide high melt fluidity, while BC - 52 can guarantee good impact resistance and strength. The following table lists the effects of these two kinds of products on the performance of PBT resins at different levels of addition.
