PC/ABS Covestro FR3040
PC/ABS Covestro FR3040
PC/ABS Covestro FR3040 is a flame‑retardant, easy‑flow alloy material. It combines mechanical strength and heat resistance of polycarbonate (PC) with processing performance of ABS.
Main Applications
Electrical‑Electronic: housings and internal parts for notebooks, desktops, copiers, printers and other business equipment; also widely used in telecommunication devices (mobile‑phone housings), home appliances, switches and sockets.
Automotive Industry: automotive interior parts.
EV Field: Derivative grade FR3040 EV specially for EV battery‑module components.
