Fire protection of plastics

摘要

For the fire protection of thermoplastic engineering resins,phosphinate-based flame retardants(FRs)are the alternative to established products such as halogenated FRs.The types of phosphorus-based FRs shown in Figure 1 are mainly used in polyamides,polyesters,polyolefins and styrenics.In view of the large number of available FR compounds on the market,it is important to know about the chemical structure of the FRs,which leads to differences in the performance of materials.
