Products Description
Polycarbonate is an amorphous thermoplastic engineering polymer synthesized by the polycondensation reaction between bisphenol A and phosgene. Compared with conventional general‑purpose plastics, it features excellent transparency, remarkable impact resistance and superior heat‑deflection performance.
During polymerization, strict control over the melt flow rate (MFR) and impurity levels delivers stable melt flow for injection‑molding processes, which effectively avoids molding defects including silver streaks, bubbles and cracking in finished parts.
Given its low moisture‑absorption property, drying treatment is necessary before processing to prevent hydrolytic degradation under high molding temperatures.

Product Application
The main applications of polycarbonate resin center on two major downstream fields: transparent components for consumer electronics and automotive structural parts.
In the electronics industry, it is extensively adopted for injection‑molded parts such as mobile phone housings, charger enclosures, LED lamp covers and optical lenses. For the automotive industry, it is utilized to manufacture headlamp covers, instrument panels and safety‑related interior components.
This product is normally packed in standard 25 kg kraft paper bags lined with PE for bulk shipments. Complete documents including COA, MSDS and physical‑property test reports can be supplied to facilitate import customs clearance for overseas plastic processors. Custom grades with tailored MFR values and anti‑UV performance are also available for long‑term manufacturing partners.
