Advantages of PMMA diffusion sheet

Led Diffuser is used as a light diffusion plate for uniform light, shielding light source, Light Guide Plate dot and defects.
Optical diffusion plate is also known as PMMA diffusion plate, commonly known as acrylic diffusion plate.

PMMA diffusion plate has excellent weather resistance, which is generally used indoors. It is guaranteed that it will not be yellow and inconvenient to be brittle within three or five years (it is not easy to have yellowing phenomenon in the ultraviolet aging accelerated test), and it also has good high temperature performance.

Light Diffuser

The Lighting Diffuser Sheet has good printability and spraying performance. With appropriate printing and spraying processes, it can give acrylic products an ideal surface decoration effect.
Flame resistance: non self igniting and non self extinguishing.
High dimensional stability: small water absorption warpage, excellent dimensional stability;

The characteristics of Polycarbonate Sheet are as follows:
It has very good chemical stability, thermal stability, optical transmission characteristics, strong refractivity, strong electrical insulation characteristics and very small moisture absorption tendency. It can be used in humid environments and has high radiation resistance. It is resistant to water and diluted inorganic acids. At the same time, it has the characteristics of brittleness, low impact strength, poor weather resistance, and is prone to yellowing and brittleness when exposed to outdoor for a long time. Its heat resistance is also poor, the deformation temperature is 70-90 °, and it can only be used in the environment below 70 °. Its low temperature resistance is also poor, and the embrittlement temperature is - 30.
