Further non-PTFE anti-drips enter market
A number of companies are now offering non-PTFE (non-PFAS) anti-drip additives to achieve UL 94 V-0 fire safety performance. Tolsa (pinfa member) offers specialist organo-clays which enable PIN FR compounds to achieve V-0 in a range of polymers (EVA, polypropylene, EPDM, unsaturated polyesters, polyamides, PVC), see pinfa Newsletter n°156 and webinar. Avient (pinfa member) has also launched a non-PFAS flame retardant polycarbonate (see pinfa Newsletter n°154). LG Chemicals has announced a UL 94 V-0 PC/ABS, using without PFAS anti-drip, produced with over 50% recycled plastics, as well as V-0 non-PFAS PC and PBT. Elementis has launched organoclay PIN FR synergists to replace PTFE, as a processing aid (shear thinning, improving processing under high mechanical stress conditions), to improve product mechanical performance and anti-drip, with smooth white or darker colour products.
