Polycarbonate (PC)
Polycarbonate is a highly durable, transparent plastic known for impact resistance and optical clarity. It is often used as a lightweight alternative to glass. Despite being tough, it can be shaped and thermoformed easily, making it ideal for engineering and safety applications.
- High optical clarity
- Superior impact and heat resistance
- Good dimensional stability
- UV-resistant with additives
• Safety glasses, lenses
• Machine guards
• Roofing sheets
• Medical devices
