Specifications pc sheet also called polycarbonate sheet , is a comprehensive performance excellent engineering plastics.
polycarbonate board also called polycarbonate sheet , is a comprehensive performance excellent engineering plastics with excellent physical, mechanical , electrical and thermal properties, euphemistically called " transparent plastic king ." Raw materials for its production of the pc hollow sheet is divided into series ( and Mingkabulong , no broken glass ) and solid board series ( also known as polycarbonate panels , transparent plate ) , have light , UV , flame retardant , weather etc., are widely used in public, civil canopy lighting and block the channel roof, elevated road noise walls , shopping mall roof , a greenhouse , is currently the world's best shed a light material . polycarbonate plate performance 1 , light : accounts for only half of ordinary glass , and difficult to break , handling the installation saves time and effort , especially for tall buildings . 2, the light transmittance: colorless, transparent solar panels provides excellent transparency and surface gloss , color plates can stop the strongest part of the sun , so that through the soft light. Transmittance as high as 92%. 3 , noise performance : can effectively reduce the noise in the international arena is the preferred material for highway noise barriers . 4 , heat resistance: more than ordinary glass and other plastics, thermal conductivity (K value ) , so that the heat loss is greatly reduced, the device used to warm the building is environmentally friendly materials . 5 , impact resistance : PC is the best impact resistance thermoplastic kind , made ??by the PC sunshine board more in a wide range of temperatures for a long time to maintain a good impact resistance, there is "no broken glass "and" ring of steel "reputation. 6 , anti-condensation : usually the case , when the outdoor temperature is 0 °C, the indoor temperature is 23 °C, as long as indoor humidity below 80% , not condensing surface of the material . 7 , flame retardant , fire : a good fire resistance, by the National Fire Monitoring Centre Building Materials testing, according to GB8624 - 1997 standard , to achieve flame retardant B1 level. Sheet own ignition 630 °C, the combustion process does not produce toxic gases do not contribute to the spread of fire from the fire extinguishing . 8 , chemical resistance : at room temperature, the ability of various organic acids, inorganic acids, vegetable oils , neutral salt solutions, aliphatic hydrocarbons and alcohol erosion. Sunshine board dissolved chlorinated paraffins , slightly soluble in aromatic hydrocarbons and ketones, can be base damage, in the day that water , methanol will be swollen . ( Detailed explanation ) 9 , cold bending installation , heat, cold , -40 to 120 degrees Celsius in the long-term physical performance and stability. 10 , co-extruded UV layer , the body can absorb 98% of the harmful ultraviolet rays ; 11 , electrical insulation, forming and hot workability
