Let’s talk about these different diffuser sheet in indoor lighting application:

PMMA diffuser sheet for lighting also known as acrylic diffuser sheet,

1. PMMA diffuser has a good high temperature resistance performance and stability, it could be 3 or 5 years not change to yellow and brittle when applied in indoor condition, which is verified in the ultraviolet aging accelerated test,the PMMA diffuser sheet is not easily yellowing phenomenon.

2. High dimensional Stability: water absorption warpage is small, the size of good stability;

3. Excellent quality assurance: Can pass UL-94 and RoHS disable poison test.


PS diffuser, PS is the polystyrene shorter form; PS diffusion plate has the characteristic as following:

1.Comparatively, the price of PS diffuser is lower than PMMA diffuser and PC diffuser,

2.Suitable for CNC machining, thermoforming. Considering the ease of integration, laser cutting processing is not suggested.

3. Surface scrub treatment, wear-resistant, scratch-resistant stability, the recommended use of the ambient temperature of 60-80 degrees.

4. The dimensional stability is good, the shrinkage rate of die making is within the 0.45% range.

5. With good surface antistatic properties, to prevent dust adsorption

6. Transmittance: 35%-85% (Adjustable range)

Above characteristics, visible PS diffuser plate has very good chemical stability, thermal stability, optical transmittance, strong refraction, electrical insulation, and very small moisture absorption, can be used in a humid environment, High radiation resistance. It can resist water and dilute inorganic acids.
