Polymer Technology and Services (PTS, Murfreesboro, Tennessee), a global flame-retardant engineering thermoplastic compounder, has introduced four new halogen-compliant polycarbonates for electrical and electronics applications.
The new Tristar AR compounds achieve UL94-V2, B0 and V1 or 5VA and V0 depending on thickness and grade. Non-mains electrical equipment (hand held) generally requires UL94-V2 or UL94-V0, whereas mains equipment requires UL94-V0 and unattended mains equipment (e.g. electrical, telcommunications) require the more demanding UL94-5VA. The Tristar polycarbonate compounds combine these levels of fire safety performance with high material strength and flexibility for recycling and reuse. They are ULK certified 746R and 746H, meaning that they do not contain chlorinated or brominated substances conform to IEC 61249.
