Polylac® PA-765A Flame Retardant High Flow ABS Resin
POLYLAC PA-765A is a flame-retardant ABS resin. It meets strict fire standards (UL94 V-0 at 2.1mm, 5VA at 2.5mm), ideal for electronics, car parts, and appliances. Its high flow (48 ml/10min) fills complex molds smoothly, perfect for thin walls like power outlets or printer casings. Durable against impacts (22 kJ/m²) and heat (up to 93°C), it’s trusted for coffee machines, TV frames, and more. UL-certified and Yellow Card-compliant. For details, check the PA-765A datasheet.
