1. PC board is made of polycarbonate by CO extrusion technology. PVC board is a board with honeycomb mesh structure in cross section made of PVC as raw material, with PVC as the main component.

2. The density of PC board is less than that of PVC board, the continuous use temperature is higher than that of PVC board, and the light transmittance is better than that of PVC board. PC board has a wide range of applications and can be used in outdoor environment with good sound insulation. PVC board is not resistant to aging and generally cannot be used in outdoor environment. PC board is an excellent insulator material, while PVC board is a polymer with good electrical properties, which is often used as low-frequency insulating material.

3. In the process of construction, PC plate is easy to install because of its strong rigidity and large coefficient of thermal expansion and cold contraction. However, PVC can not be used in outdoor lighting because it does not resist the characteristics of old fire and inflammable.

4. PVC board and PC board have strong corrosion resistance, but their corrosion resistant objects are different. PVC board can resist most inorganic acids, alkalis, salts and most organic solvents, and can be used as anti-corrosion materials in medicine and chemical industry; PC board has good resistance to acid, alkali, salt with strong concentration in air and water, as well as a variety of oils and solvents.
