PBT specific halogen-free flame retardant BM-15
Introduction
BM-15 is a halogen-free flame retardant designed by our company specifically for PBT/PA, with phosphorus and nitrogen as the main flame retardant elements. Not subject to RoHS and REACH regulations; It has the characteristics of high flame retardant efficiency, good thermal stability, no precipitation, good water resistance, light aging resistance, and low smoke and non toxicity. Has very high thermal stability, decomposition temperature ≥ 360 ℃
