PS diffuse sheet is the one kind of PS sheet with light diffusivity. PS sheet also calls polystyrene or GPPS sheet, and the petrochemical is a relatively low-order transparent brittle. The proportion is 1.047 ~ 1.049 in the full transparency Transmittance of 87%. It is the second high transparent in plastic refractive index after the PC material. But it is easy to be yellow and very easy to brittle in the cold weather.


PS diffuser characteristics

1.Relatively speaking, the price is low;

2.Weather resistance is worse than PMMA. Using in outdoor moisture is brittle and yellow more obvious;

3.The density polystyrene of 1.05 or so, than PMAM (1.2) light, PP (0.96) heavy;

4.It’s suitable for mechanical processing and thermoforming; Because it is easy to melt, we don’t recommended to do laser cutting

5.It is frosted, wear, anti-scratch and stability, which the using temperature is 60-80 degrees.

6.Good dimensional stability, mold production shrinkage within 0.45% range.

7.It has a good surface antistatic property to prevent dust adsorption

8.light transmittance: 60% -80% (range adjustable)
