Weight: At 1.2 g/cm³ compared to glass's 2.5 g/cm³, they're half as heavy, making handling and installation easier.
Fire Resistance: Their UL94 V-2 rating indicates slow burning properties, though they may release flaming droplets. Special grades provide enhanced fire safety.
Chemical Resistance: While resistant to many acids, bases, and solvents, they can be damaged by chemicals like acetone. Industrial applications require careful compatibility testing.
UV Resistance: Standard sheets may yellow with UV exposure, but UV-stabilized versions resist this effect—particularly important for greenhouse roofs.

Darker Tints (Gray, Bronze):Transmit 10–50% visible light, reducing glare and brightness.
Lighter Tints (Opal, Milky): Transmit 50–85% light, offering diffused illumination (ideal for greenhouses).
Colored Tints (Green, Blue): Vary by shade; green often transmits 60–70% (favors plant growth), while blue may reduce harsh sunlight.
Opal/Milky: Moderate heat blocking but excel at diffusing light to eliminate hotspots.
Special Coatings: Some sheets include low-E (low emissivity) or IR-reflective layers for superior thermal control.
Neutral Tints (Gray, Bronze): Blend with architectural designs; bronze offers a warm hue.
White/Opal: Provide a clean, modern look with soft light diffusion.
Colored Tints (Green, Blue): Used for branding, mood lighting, or agricultural filtering (green promotes plant growth).
Bronze/Gray: High glare reduction, suitable for skylights or automotive applications.
Opal: Reduces glare through light diffusion rather than absorption.
Yes. PC is hygroscopic and must be dried at 120-130°C for 3-4 hours (moisture content <0.02%).
Our Advantage: Pre-dried customized materials available with guaranteed moisture compliance, reducing your production energy costs.
PC offers excellent toughness but can be surface-hardened for demanding applications. Our advanced solutions include:

This comprehensive survey ensures all aspects are covered, providing a complete resource for understanding clear polycarbonate sheets.
PC excels in CNC machining for prototyping and low-volume production. Achieve <0.01mm tolerances with our guidelines:
Cutting Tools:
Carbide end mills with polished flutes (15° helix angle)
Diamond-coated drills for hole consistency (Aerospace Standard AS9100 compliant)
Geometry:
2-flute for roughing (chip clearance optimization)
4-flute for finishing (Ra <0.8μm achievable)
| Operation | Speed (SFM) | Feed (mm/tooth) | Depth of Cut (mm) |
|---|---|---|---|
| Milling | 300-500 | 0.05-0.15 | ≤2×tool diameter |
| Drilling | 200-400 | 0.03-0.08 | Peck drilling cycle |
| Engraving | 600-800 | 0.01-0.03 | 0.1-0.3 |
Pro Tip: Use compressed air cooling (no lubricants) to prevent stress cracking.
