First, let us review the features of diffuser acrylic sheet.
• High Brightness: With the same transmittance, the brightness can be improved compared with the traditional diffuser.
Excellent masking effect: good light diffusion and homogenization ability, excellent effect of shading lamp.
• High dimensional stability: low water absorption and warpage, excellent dimensional stability.
• Excellent durability: yellowing is not easy in the accelerated aging test of UV light.
• Outstanding Quality Assurance: All products are UL-94 and RoHS-compliant with Toxicity Test. B, technical indicators
