Oct 21, 2021
Advantage&shortcoming of diffuser material
PMMA
Acrylic
1. High transparency, low turbidity
2. Strong weather resistance and UV resistance
3. Good processing performance, suitable for mechanical processing, thermoforming, laser cutting and engraving
4. Resistance to common solvents
5. Moderate price
The impact resistance is not good enough, but the impact-resistant modified acrylic sheet can meet the resistance performance requirements of most occasions
PC
Polycarbonate
Strong impact resistance
1. Poor weather resistance and sensitivity to sunlight
2. The surface is not wear-resistant and easy to scratch
3. Poor solvent resistance
4. Large forming stress, easy to crack
5. Higher processing cost
6. High price
PS
Polystyrene
1. Good fluidity and easy processing
2. Cheap
1. Low transparency
2. Very poor weather resistance, easy to yellow
3. Dense smoke is produced during combustion
4. Poor solvent resistance and fragile
PVC board/light box cloth
Polyvinyl chloride
1. The sheet has a certain strength
2. Low price
1. Very low transparency
2. The surface is not wear-resistant
3. Poor weather resistance, easy to yellow and lose gloss
4. The light box cloth is troublesome to install and has low wind resistance
PETG
Modified polyester
1. Good ductility and high stretch ratio
2. Solvent resistance is stronger than PC
1. Very poor weather resistance and UV resistance
2. Low transparency and non-wearing surface
3. The price is too high
