This 20mm milky diffusion polycarbonate multi-wall sheet adopts multi-layer vertical rib hollow structure with opal diffusing formula. It can scatter incoming light evenly, eliminate bright spots and glare while maintaining proper light transmittance. One side is coated with UV protective layer to block ultraviolet rays, preventing yellowing and aging under long-term outdoor exposure. The multi-wall structure delivers superior thermal insulation and high rigidity, suitable for large span roofing. It features lightweight, high impact resistance and safe replacement for glass. It can be cut, drilled and cold bent for on-site fabrication. Printed PE protective film carries product introduction and performance parameters to guide construction. Double-sided PE film protects surface against scratches during transit and installation.

Q2: Can this diffusion sheet be used outdoors?

A: Yes, with UV coating on one side to resist UV radiation and slow down yellowing.

Q3: How about light transmittance?

A: Medium light transmission with excellent scattering effect, delivering soft glare-free lighting.

Q4: Are other thicknesses available for diffusion multi-wall PC sheets?

A: 10mm,16mm,20mm,25mm optional, clear, blue, bronze colors also available on bulk orders.

Q5: Can we cut sheets to custom dimensions?
