LED Light Diffuser Made of Polycarbonate Plastic

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 for downlights, panel lights, advertisement billboards, the light covers of the printed circuit board, office lamps, kitchen lights, and fluorescent lights. 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 a 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 displayers, LED screens, mobile phone screens, membrane switches, etc. It is also made of high-quality polycarbonate plastic. The thickness ranges from 0.06mm to 0.8mm.

Compared with the PMMA diffuser, the 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 provides light diffusers with custom size, machining service, and OEM service for more than 1200 clients from more than 40 countries.

Main Benefits of Light Diffuser Film

Incomparable Impact Resistance: Polycarbonate Diffuser is 25 times stronger than Plexiglass Diffuser, it is an unbreakable light diffuser material;
By using high-quality polycarbonate and light-diffusing additives, the light diffuser panel offers less LED “Hot Spots”;
UVPLASTIC polycarbonate led diffuser panel has more brightness for great energy efficiency;
Polycarbonate Diffuser Panels can be formed into complex shapes such as curved light diffusers. Otherwise, it is easy to cut, drill, bend carve without breaking;
Outstanding flammability characteristics;
Easy to cut and mold to any shape, UVPLASTIC also provides Machining service;
It can be used outdoors;

Frequently Asked Questions

Yes, UVPLASTIC can cut it to any size and shape according to clients’ drawings.

Yes, UVPLASTIC can thermal form LED light diffuser.

Yes. Polycarbonate diffusers are the best diffuser panels for LED panel light. The popular thicknesses are 0.5mm, 0.8mm, 1mm, 1.2mm, and 1.5mm. Of course, you can find other diffuser panels, such as PS diffusers, PMMA diffusers, etc. However, polycarbonate diffusers offer better impact resistance and a longer lifespan.

Yes, the main material of the UVPLASTIC Plastic Light Diffuser is polycarbonate, which is 250 times stronger than glass and 25 times stronger than acrylic. It is virtually unbreakable.

Yes, we have LED light diffuser sheet for outdoor use.

Yes. What we can provide is not only the high-quality polycarbonate light diffuser sheet but also the machining service.

The main differences are:

Impact resistance: Polycarbonate is 25 times stronger than acrylic;
The hardness of surface: acrylic offers better surface hardness than polycarbonate;

It will depend on the application, if you have a high requirement for impact resistance, the polycarbonate diffuser will be better.
