Best Light Diffuser Solution by Polycarbonate Plastic

UVPLASTIC™ Light Diffuser and non-glare light diffuser sheets are made of polycarbonate plastic, which is mainly used as the cover protection of the downlight, panel light, advertisement billboard, light cover of the printed circuit board, office lamp, kitchen light, fluorescent light. It can scatter light spots equably on the surface, then, you can get soft and comfortable light rays. UVPLASTIC™ Polycarbonate Light Diffuser is an efficient and excellent light diffuser material, the thicknesses are from 0.8 mm to 5mm, it is also known as “LED Light Diffuser“, “Polycarbonate Diffuser“.

UVPLASTIC provides the high-quality reflection film, which is made of polycarbonate plastic, the thickness ranges from 0.2mm to 0.4mm, which offers great light reflection capability and works well at temperatures between -40 and 120 degrees. Reflection film is also one of the main parts of LED Lights. Otherwise, UVPLASTIC developed diffuser film for displayer, LED screen, mobile phone screen, membrane switch, etc. It is also made of high-quality polycarbonate plastic. The thickness ranges from 0.06mm to 0.8mm.

Compared with the PMMA diffuser, polycarbonate diffuser offers higher impact resistance, better flame retardance, and dimensional stability in a large temperature from -40 °C to 120 °C. Therefore, It is the right material for the LED lamp, LED sign, architectural lighting system, elevator lighting system, railcar lighting system, etc. Otherwise, Polycarbonate Diffuser Sheet/Film is also the right choice for industrial applications including electron industry, machine vision system, and medical device inspection.

With more than 15 years of experience in manufacturing polycarbonate diffusers, UVPLASTIC has grown to be a leading manufacturer of Light Diffuser Sheet in China and providing light diffusers with custom size, machining service, and OEM service for more than 1200 clients from more than 40 countries.
