PolyVisions, a Pennsylvania based specialist compounder (a wholly owned subsidiary of Bemis Associates Inc.), has launched DuraPETTM FR, a new material offering exceptional chemical resistance, fire performance and impact strength, temperature tolerance of -40 to +180deg Celsius and fire performance to UL94 V0 (1.5 mm).
The material is based on polyethylene terephthalate (PET) which is graft modified and includes a phosphorus-based polymeric flame retardant from pinfa member FRX Polymers. It can be processed by injection moulding, sheet and film extrusion, and thermoforming. A version based on recycled polyester is available. Applications include automobile, transport, medical equipment, construction, and electrical and electronic housings.
