Acrylic sheet compare with other materials

Materialadvantagedisadvantage
PMMA

1, High light transmittanc

2, Excellent weather condition, anti-UV

3, Easy to be processed, good for cutting, thermforming, CNC and laser cutting and engraving

4, Resistant to common solvents

5, Competitive prices

The impact resistance is not good enough, but the impact-modified acrylic plate can meet the requirements of the resistance performance in most occasions
PCExcellent impact resistance

1, Poor weather resistance and sensitivity to sunligh

2, The surface is not wear-resistant and easily scratched

3, Poor solvent resistance

4, Large molding stress, easy to crack

5, Higher processing cost

6, High price

PS

1, Good fluidity and easy to proces

2, cheap

1, Low transparency

2, Very poor weather resistance, easy to yellow

3, Thick smoke when burning

4, Poor solvent resistance and fragile

PVC

1, The board has a certain strength

2, cheap

1, Very low transparenc

2, The surface is not wear-resistant

3, Poor weather resistance, easy yellowing and loss of light

4, Light box cloth installation trouble, low wind resistance

PETG

1, Good ductility and high draw ratio

2,PCSolvent resistance is stronger than PC

1, Very poor weather resistance and UV resistanc

2, Low transparency, the surface is not wear-resistant

3, High price
