What are the characteristics of hollow polycarbonate sheet?

Hollow polycarbonate sheet, also known as polycarbonate sunshine sheet, glass capron sheet, polycarbonate sheet, etc., is made of high-performance engineering plastic polycarbonate resin, with high transparency, light weight, impact resistance and sound insulation , heat insulation, flame retardant, but it is not acid and alkali resistant. It is a high-tech, energy-saving and environmentally friendly plastic sheet with excellent comprehensive performance. Let's take a look at the characteristics of this type of product together.



Features of hollow polycarbonate sheet

1. Light transmittance: The light transmittance of PC board can reach up to 89%, which is as good as glass. UV-coated panels will not produce yellowing, atomization and poor light transmission under sunlight. After ten years, the loss of light transmission is only 6%, while the loss rate of PVC is as high as 15%-20%, and the glass fiber 12 %-20%.


2. Impact resistance: The impact strength of PC sheet is 250-300 times that of ordinary glass, 30 times that of acrylic plates of the same thickness, and 2-20 times that of tempered glass. It will not crack even when it is dropped from high ground.


3. Light weight: the light of panel is only half of that of glass, saving the cost of transportation, handling, installation and supporting frame.

4. Flame retardant: The national standard GB50222-95 confirms that the PC board is flame retardant grade 1, namely B1 grade. The ignition point of the PC board is 580℃, and it will self-extinguish after leaving the fire. It will not produce toxic gas during combustion and will not promote the spread of the fire.


5. Flexibility: According to the design drawing, cold bending can be used on the construction site, and it can be installed into an arch to make semi-circular roof and window. The minimum bending radius is 175 times the thickness of the adopted plate, and hot bending can also be used.


6. Sound insulation: PC board has obvious sound insulation effect, and has better sound insulation than glass and acrylic board of the same thickness. Of the same thickness, the sound insulation of PC board is 3-4DB higher than that of glass. Internationally, it is the material of choice for highway noise barriers.


7. Energy saving: keep cool in summer and keep warm in winter. PC board has a thermal conductivity (K value) lower than ordinary glass and other plastics, and the heat insulation effect is 7%-25% higher than that of the same glass. Thus, the heat loss is greatly reduced. It is used in buildings with heating equipment and is an environmentally friendly material.


8. Temperature adaptability: PC board will not be cold brittle at -40℃, and will not be softened at 125℃, and its mechanics and mechanical properties will not change significantly in harsh environments.
