Comparison dimension |
PC board |
Similar materials (such as glass, PMMA, PVC, ABS) |
Optical properties |
High transmittance and adjustable haze, UV coating weather resistance>10 years |
Glass has high transmittance but is fragile; PMMA has a transmittance>92% but poor weather resistance; PVC has low transmittance. |
Mechanical properties |
Excellent impact resistance, 200-300 times that of glass and 10-20 times that of PMMA, suitable for high-security demand scenarios |
Glass is brittle; PMMA has average impact resistance; PVC has low rigidity. |
Temperature resistance |
Continuous use temperature -40℃ to 120℃, heat deformation temperature 125-140℃, better than PMMA and PVC |
PMMA is easy to soften at high temperature; PVC is easy to decompose at high temperature. |
Chemical resistance |
Resistant to weak acids and alkalis, not resistant to strong acids/alkalis and organic solvents, but better than PMMA and PVC |
PMMA has average chemical resistance; PVC has good acid and alkali resistance but poor organic solvent resistance. |
Processing performance |
Good melt fluidity, can be hot-bent, cold-bent, stamped, welded, and has no moisture absorption and deformation problems |
Glass needs to be cut and drilled; PMMA processing temperature is sensitive; PVC needs to add plasticizers. |
Cost and environmental protection |
Moderate overall cost, recyclable, UV coating is environmentally friendly and non-toxic |
High glass recycling cost; PMMA recycling is difficult; PVC contains chlorine. |
