Advantages And Disadvantages Of LED Light Guide Plate Material PMMA/Acrylic

Acrylic, also known as specially treated plexiglass, is a replacement product of plexiglass

The light box made of acrylic has the characteristics of good light transmission, pure color, rich color, beautiful and flat, giving consideration to both day and night effects, long service life, and no impact on use.

At present, PMMA/Acrylic is widely used in LED light guide plate materials on the market. Compared with plexiglass, PC and PS have the disadvantages of high light transmittance, strong stability, wide temperature resistance range, etc. The specific advantages and disadvantages and precautions are as follows

Compared with plexiglass, acrylic has the following characteristics:

1. Good transparency. Colorless transparent plexiglass plate, with a light transmittance of more than 92%

2. Excellent weather resistance. It has strong adaptability to the natural environment, even if it is exposed to sunlight, wind and rain for a long time, its performance will not change, and its anti-aging performance is good.

3. The processing property is good. It is suitable for machining and easy for hot forming

4. Excellent comprehensive performance. Acrylic board has many varieties, rich colors and excellent comprehensive performance.

Pay attention to the following points when using:

1. Acrylic plate shall not be stored in the same place with other organic solvents, nor shall it contact with organic solvents.

2. The surface protective film or protective paper shall not be scratched during transportation.

3. It cannot be used in an environment where the temperature exceeds 85 ℃.

4. When cleaning acrylic plates, only 1% soapy water shall be used, and soft cotton cloth shall be dipped with soapy water. Hard objects or dry scrubbing shall not be used, otherwise the surface will be easily scratched.

5. Acrylic plate has a large coefficient of thermal and cold expansion, and expansion clearance shall be reserved due to temperature change.
