Abrasion resistance: After anti-UV coating treatment, the abrasion resistance of PC board can be increased several times and is similar to glass. Hot forming can be cold bent into a certain arc without cracks and can be cut or drilled again. Anti-theft, anti-gunshot PC can be pressed together with glass to form security windows for hospitals, schools, libraries, banks, embassies and prisons, where the glass improves the hardness and abrasion resistance of the sheet. PC can also be pressed together with other PC layers or acrylics for traditional security applications.

UV protection:Ultra-violet protection, only some single-layer surfaces turn yellow or hazy under prolonged sunlight. PC board has excellent thermal insulation performance, which is about 16% higher than glass under the same thickness, and can effectively block heat transmission. Whether it is to keep warm in winter or to stop the heat from invading in summer, PC board can effectively reduce building energy consumption and save energy.

Anti-combustion performance:PC board has good flame retardancy, does not produce toxic gas when burning, its smoke concentration is lower than that of wood and paper, and is identified as a first-class flame-retardant material, in line with environmental protection standards. After 30s of burning samples, its burning length did not exceed 25mm, and only decomposed flammable gas when the hot air was as high as 467℃. Therefore, after the relevant measurement, it is considered that its fire performance is qualified.

Resistance to chemical substances can:force no reaction to acid, alcohol, juice, beverage; also have some resistance to gasoline, kerosene, in contact with 48h will not appear cracks or lose light transmission ability. However, the chemical resistance to certain chemicals (such as amines, esters, halogenated hydrocarbons, paint flushing agents) is poor.

Light weight: density of polycarbonate is about 1.29/cm, about half lighter than glass, such as made of hollow PC board, its mass is 1/3 of organic glass, glass 1/15 ~ 1/12 or so. Hollow PC board has excellent stiffness and can be used as a skeleton member. the light weight of PC board makes the construction safer and more convenient, and can greatly save shipping and goblet construction time and cost.
