Polymer Properties:

1. Base Material: Polycarbonate (PC)
2. Modification Features:
   
   • High – impact strength and heat resistance combination.
   • Good chemical resistance and UV resistance.
   • Suitable for complex part designs with good mold – filling properties.
   • Dimensional stability for precision parts.

Applications:

• Architectural and Building Glazing: A popular choice for corrugated sheets, multi-wall sheets, and protective glazing (e.g., skylights, canopies) due to its durability, light weight, and weatherability.
• Protective Equipment: Its high impact resistance and optical clarity make it suitable for safety goggles and helmet visors.
• Lighting Components: The material’s UV stability and transparency are ideal for outdoor lighting fixtures, including LED lamp covers and light diffusers.
• Automotive: Can be used for exterior and interior parts, such as certain headlamp housings and transparent components requiring UV protection.
• Security Applications: Its toughness makes it a component in some bulletproof windows and protective barriers.
