Product Description

High Flame Retardant Efficiency Specific for PBT B


BM-15 is especially designed for PBT, with phosphorus, nitrogen as the main flame retardant elements. It is free from the restrictions of RoHS and REACH. The products with BM-15 are characterized by high flame retarded efficiency, good thermal stability, no immigration, excellent water resistance, good aging resistance as well as low smoke non-toxicity. BM-15 features quite high thermal stability, with high decomposition temperature ≥ 360℃.
