PC (Polycarbonate)

High-Performance Plastic for Tough Applications

Polycarbonate (PC) is a high-performance thermoplastic known for its exceptional toughness, optical clarity, and heat resistance, making it an ideal choice for demanding applications that require durability and transparency. Its unique combination of impact resistance and lightweight properties makes PC a preferred material across various industries, including automotive, electronics, construction, and consumer goods. Unlike other plastics, polycarbonate offers a level of strength that allows it to withstand high-impact forces without cracking or breaking, even in extreme conditions, making it suitable for safety applications like protective eyewear and safety shields.

One of the standout properties of PC is its optical clarity, making it ideal for transparent applications such as eyewear lenses, automotive lighting, and optical discs. Its ability to maintain transparency while offering high-impact resistance sets it apart from other clear plastics like acrylic. Furthermore, polycarbonate is highly heat-resistant and able to endure high temperatures without deforming, which makes it suitable for use in automotive components, electrical housings, and heat-resistant parts. The versatility of PC allows it to be processed through a range of manufacturing techniques, including injection molding, blow molding, and thermoforming, making it a flexible option for producing complex parts with high precision
