Advantages and disadvantages of LED light guide material PMMA/ acrylic acid

Acrylic resin, also known as specially treated plexiglass, is an alternative to plexiglass

 

The light box of acrylic material has the characteristics of good light transmission, pure color, rich color, beautiful and smooth, taking into account the day and night effect, long service life, and does not affect the use of.

 

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

 

Compared with plexiglass, acrylic resin has the following characteristics:

 

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

 

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

 

3. Good processing performance. Suitable for machining, easy to thermoform

 

4. Excellent comprehensive performance. Acrylic plate variety, rich color, excellent comprehensive performance.

 

Note the following points when using:

 

1. The acrylic sheet shall not be stored in the same place as other organic solvents, nor shall it be in contact with organic solvents.

 

2. Do not scratch the surface protective film or protective paper during transportation.

 

3. Do not use in an environment where the temperature exceeds 85 ° C.

 

4. When cleaning the acrylic sheet, only use 1% soapy water and dip a soft cotton cloth in the soapy water. Do not use hard objects or dry scrubbing, otherwise the surface is easy to scratch.

 

5. The acrylic sheet has a large thermal expansion coefficient and cold expansion coefficient, and the expansion gap should be reserved due to temperature changes.
