PC/ABS CHIMEI PC‑540A
PC/ABS CHIMEI PC‑540A
PC/ABS CHIMEI PC‑540A is a halogen‑free flame‑retardant alloy material with good heat resistance. It combines the strength and heat resistance of polycarbonate (PC) with the processing flowability of ABS.
Main Applications
Electrical‑Electronic: set‑top boxes, projectors, display front bezels, 3C digital products, transformers, game consoles, small tablet computers, network‑communication products, etc.
Computers & Accessories: high‑tech products such as computer housings and attachments.
