High-Flow Efficiency

With a melt flow index of 47 ml/10 min, PA-763H fills intricate molds rapidly, reducing cycle times and energy costs. Perfect for thin-walled components like printer casings or power outlets.

Reliable Flame Retardancy

It achieves UL 94 V-0/5VB/5VA ratings at minimal thicknesses, ensuring compliance with strict safety standards. Ideal for electrical panels, car audio consoles, and appliances where fire safety is critical.

Heat & Weather Resistance

It withstands temperatures up to 92°C (HDT) and resists UV degradation, making it durable for outdoor light boxes, TV frames, and automotive battery housings.

Applications

Electronics: Displays, modems, power panels, DVD players, remote controls.
Automotive: Car batteries, audio consoles, rearview mirror housings.
Office Equipment: Printer casings, fax machines, projectors, cash registers.
Appliances: Coffee machines, power outlets, front/rear TV frames.
Industrial: Machine boxes, large-scale multifunctional peripherals.
