New PIN FR solutions for e-mobility PBT
Clariant (pinfa member) has launched two new phosphinate PIN FRs for performance PBT in e-mobility. The new organophosphorus PIN FRs can both achieve UL 94 V-0 @ 0.4 mm with 15-20% loading in polybutylene terephthalate (PBT), without ATO (antimony trioxide), and offer respectively exceptional hydrolysis stability or CTI (comparative tracking index) of 600V even after prolonged storage, as well as colorability, physical and electrical properties. They are also adapted for use in polyesters, PET (polyethylene terephthalate) and other technical polymers, with or without glass fibre reinforcement. They respond to increasingly demanding requirements for electric vehicles, including non-halogenated fire safety and electrical insulation and stability under demanding conditions. Both PIN FRs are not Classified as Hazardous and are not considered endocrine disruptors, not PBT, not vPvB (persistent, bioaccumulative and toxic, very persistent and very bioaccumulative).
