Polymer Compounders Ltd (PCL) new polycarbonate blend compounds show excellent properties and low toxicity. Established in 1993, PCL specialises in engineering thermoplastics. Their new PC/ABS* and PC/ASA* blends claim better melt processing, lower density and physical properties as good as halogen FR compounds, but use reactive non-halogenated FR polymer formulations to ensure a favourable toxicity profile, no antimony, no FR migration and no bioaccumulation. UL94-V0 is achieved for 0.75mm and glow wire (GWIT) 960°C. PLC says the non-halogenated FR solution will enable to keep ahead of expected EU ECHA / Reach restrictions. The PC-ABS solution offers impact performance of 46 kJ/m2 and is particularly adapted for applications such as electric vehicle battery casings which require both toughness and fire resistance.
* PC = polycarbonate, ABS = acrylonitrile butadiene styrene, ASA = acrylonitrile styrene acrylate
