ABS CHIMEI Taiwan PA‑766
ABS CHIMEI Taiwan PA‑766
Product Introduction ABS CHIMEI Taiwan PA‑766 is a flame‑retardant, high‑temperature‑resistant and high‑impact ABS resin, mainly processed by injection molding. It is suitable for electronic‑electrical parts and automotive components requiring flame retardancy and heat resistance.
Main Applications
Electronic‑Electrical Products: This is the most typical application field for PA‑766. It is widely used for electronic‑device housings (TV sets, copiers, telephones, etc.) and internal components. Its UL94 V‑0 rating (1/16 inch) meets flame‑retardant safety requirements for many electronic products.
Automotive Parts: Automotive instrument panels, exterior body panels, interior trims, steering wheels, sound‑insulation panels, door locks, bumpers, ventilation ducts.
Building Materials: Certain building structural components.
