Molecular Structure:

B、Application: This product is additive flame retardant. It is mainly used in PC and PC/ABS resins. It has good flame retardancy on epoxy resin, it can be used to make EMC for IC Packaging, it’s flame retardancy is better than Brominated flame retardant, can reach UL-94V0 grade. Oxygen index could reach 33.1%. When it is used in Benzoxazine Resin glass cloth laminate, if the HPCPZ mass fraction is 10%, the scale of burning could reach V-0 grade, the parallel breakdown voltage is 47KV. When it is used in Polythene, the LOI of final flame retardancy polythene could reach 30-33. After used in viscose spinning solution, we could get the flame retardant viscose fiber with oxygen index 25.3-26.7. If the added amount is 12% in PC/ ABS, it could pass the UL-94 V0 test. It also can be used in LED, powder coating, potting material and polymers.
