Why Choose Our Polycarbonate Sheets?

As a leading manufacturer specializing in engineering thermoplastics, we produce Polycarbonate (PC) sheets that bridge the gap between glass-like transparency and metal-like strength. Whether you need solid glazing, multi-wall insulation, or custom-formed parts, our factory-direct model ensures you get the highest quality at competitive prices.

We combine advanced extrusion lines with over 18 years of experience to deliver sheets that offer superior clarity and weatherability for a wide range of industries.

 

Key Properties of Our PC Sheets
 

If you are browsing for a material that needs to withstand extreme conditions, here is why PC is the optimal choice:

  • Impact Resistance: 250 times stronger than glass and 30 times stronger than acrylic. Ideal for security glazing and machine guards.
  • Lightweight: Half the weight of glass, reducing structural support costs and making installation easier.
  • High Light Transmission: Optical clarity up to 89% (comparable to glass) for clear grades.
  • Temperature Resistance: Effective operating range from -40°C to 120°C, suitable for both cold storage and high-heat environments.
  • Flame Retardancy: Self-extinguishing material with high resistance to ignition (UL94 V-2 rated available).

UV Protection:

Ask us about our co-extruded UV protection layer. Unlike sprayed coatings that can wear off, our permanently fused layer prevents yellowing and extends the life of the sheet by 5-10 years-making it ideal for outdoor applications like greenhouses and signage.

1. Advanced UV Protection & Weather Resistance
  • Co-Extruded UV Protection Layer: During the manufacturing process, we fuse a sacrificial UV-resistant layer directly onto the surface of the sheet. Unlike varnishes or films that can peel or wear off over time, this co-extruded layer becomes a permanent part of the sheet, ensuring long-term protection.
  • Extended Lifespan: This layer absorbs and dissipates harmful UV radiation, preventing the polymer chains from breaking down. As a result, sheets used in outdoor applications-such as greenhouses, carports, and exterior cladding-maintain their mechanical strength and clarity for 5 to 10 years longer than unprotected standard sheets.
  • Application-Specific Advice: Not every project requires the same level of protection. If your application is indoors or away from direct sunlight, we can advise on standard grades. However, for projects where the material will face harsh sunlight, we strongly recommend (and can provide samples of) our co-extruded UV grade to ensure your end-product lasts.
