PC/ABS SABIC CX7240
PC/ABS SABIC CX7240
PC/ABS SABIC CX7240 is a well‑balanced halogen‑free flame‑retardant alloy material. It combines the mechanical strength and heat resistance of polycarbonate (PC) with excellent processing flowability of ABS.
Main Applications
New‑energy‑vehicle electronics (high‑temperature safety scenarios): BMS housings, high‑voltage connector housings, control‑module enclosures, OBC housings, charging‑pile interface covers, DC‑DC converter housings, ADAS sensor brackets, millimeter‑wave radar supports, camera bases.
High‑end consumer electronics (ultra‑thin high‑reliability structures): ultra‑thin notebook structural parts, base‑station RF unit housings, industrial tablets, explosion‑proof device touch‑screen backplates.
Medical / industrial equipment (harsh‑environment durability): medical‑sterilization devices, endoscope handles, steam‑sterilization trays.
Industrial controllers: PLC housings, HMI operator panels.
Smart‑grid equipment: outdoor electric‑meter boxes, circuit‑breaker modules.
