Many friends may mistakenly believe that hollow pc sheet and solid pc sheet are different materials, but in fact, based on their physical properties, solar panels and endurance panels are indeed the same product, and both are processed using high-performance plastic polycarbonate (PC) resin, both of which belong to the PC series of panels.   

    Although they both belong to the PC series of sheets, there are still significant differences in their practical applications. Therefore, it is important to understand the differences in their application choices. Next, Xinhai will take everyone to learn about them!


   The difference between hollow pc sheet and solid pc sheet:

    Generally speaking, PC solid pc sheet is PC solidsheet, single-layer solid; but the price is higher. PC hollow pc sheet is also called hollowsheet. As the name suggests, it is hollow in the middle. It has single layer, double layer or even multi-layer and is hollow; its sound insulation effect is much better than that of solid one, and it is not easy to cause thermal expansion and contraction. Cracked plate, but the pressure is not as good as solid plate. Judging from the weight, since the hollow pc sheet is hollow and uses less materials, the solid pc sheet with the same thickness and area is much heavier than the hollow pc sheet.

     Advantages of solid pc sheet and hollow pc sheet

     Solid pc sheet:

    Impact resistance – the impact force of the solid pc sheet can reach a maximum of 3kg/cm3, and the specific gravity is 1.34g/cm³, which is 200 times that of ordinary glass and 8 times stronger than that of acrylicsheet, and there is almost no risk of breaking.

    Transparency—Excellent lighting, light transmittance as high as 75~89%, and its transparency is comparable to glass.

    Weather resistance – surface UV agent (anti-ultraviolet) has the ability to absorb ultraviolet rays and convert them into visible light, which can guarantee ten years of non-fading outdoors.

   Flame resistance – the solid pc sheet itself does not spontaneously combust and has excellent self-extinguishing properties.

   Heat resistance, cold resistance – in the test range of minus 30°C to 130°C, it will not cause quality changes such as deformation.

   hollow pc sheet:

   Light transmittance: The light transmittance of PC sheet can reach up to 89%, which can be compared with glass. UV coatedsheets will not produce yellowing, fogging, and poor light transmission when exposed to sunlight. After ten years, the loss of light transmission is only 6%, the loss rate of PVC is as high as 15%-20%, and the loss rate of glass fiber is 12%. %-20%.

   Impact resistance: The impact strength 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. There is no crack when dropped two meters below a 3kg hammer. There are “unbreakable glass” and The reputation of “sound steel”.

   Anti-ultraviolet: One side of the PC sheet is coated with an anti-ultraviolet (UV) coating, and the other side has anti-condensation treatment, which integrates anti-ultraviolet, heat insulation and anti-drip functions. It can block ultraviolet rays from passing through, and is suitable for protecting valuable artworks and exhibits from ultraviolet rays.

   Light weight: The specific gravity is only half of that of glass, which saves the cost of transportation, handling, installation and support frame.

   Flame retardant: The national standard GB50222-95 confirms that the PC sheet is the first class of flame retardant, that is, B1 level. The ignition point of the PC sheet itself is 580 degrees Celsius, and it will self-extinguish after leaving the fire. It will not produce toxic gases when burning, and will not promote the spread of the fire.

   Bendability: According to the design drawing, the cold bending method can be adopted on the construction site to install arches, semicircular roofs and windows. The minimum bending radius is 175 times the thickness of the plate used, and it can also be hot bent.

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

   Energy saving: Keep cool in summer and keep warm in winter. PC sheet has a lower thermal conductivity (K value) than ordinary glass and other plastics. The heat insulation effect is 7%-25% higher than that of the same glass. The heat insulation of PC sheet is up to 49% %. As a result, the heat loss is greatly reduced, and it is an environmentally friendly material used in buildings with heating equipment.

   Temperature adaptability: PC sheet does not appear cold and brittle at -100°C, does not soften at 135°C, and its mechanics and mechanical properties do not change significantly in harsh environments.
