Product Description

Polycarbonate (PC) is an engineering thermoplastic renowned for its exceptional impact resistance (virtually unbreakable), high optical clarity (up to 90% light transmission), and thermal stability (service temp: -135°C). Derived from bisphenol-A monomers, it withstands harsh environments while remaining 200x stronger than glass. Dominant applications include bullet-resistant windows, electronic housings (phones/laptops), automotive headlights, and medical devices. PC processes via injection molding/extrusion but requires pre-drying to prevent hydrolysis. Though costlier than commodity plastics, its unique blend of durability, transparency, and flame retardancy (UL94 V-0 grade) makes it irreplaceable in high-performance sectors. BPA-free variants address niche health concerns. 

Features

Medium to high viscosity and excellent demolding performance.

Applications

Widely used in electronic device casings (like phones and computers), automotive parts (such as lamp covers), optical products (e.g., spectacle lenses), medical device components, etc.
