DURABIO™ D7340
- Chemical Family
- Polycarbonate (PC)
DURABIO™ D7340 is partially bio-based and truly durable engineering plastic, combining the most advantageous properties of general polycarbonate and PMMA. In addition to excellent mechanical strength, it has excellent scratch resistance and UV / weather resistance. It also has high transparency and unique optical properties. It proudly bears bio-based and BPA-free labeling claims, making it an eco-friendly choice. Ideal for consumer goods, E&E housing, and cosmetic containers. This grade is characterized by high heat resistance and is suitable for injection mold.
