Yellow beige PC board PC board PC board manufacturers custom good quality PC sheet characteristics: a, mechanical properties 1) impact strength: Excellent plastic processing professional PC board solid sheet impact performance, it is 250 times higher than conventional glass, 30 times higher than the acrylic sheet. The impact strength of PC sheet called "transparent plate," said. 2) Tensile strength, solid sheet of plastic processing professional PC board thermal resistance, even at 120 ℃, its tensile strength is still up 350kgf / cm2. 3) bending strength: PC board solid sheet of plastic processing professional bending is good, even if the bending angle of 90 °, still broken. b, thermal performance 1) Melting temperature shape: PC Solid sheet-shaped melting temperature of 135 ℃, their continuous use temperature of 120 ℃. 2) linear expansion coefficient: linear expansion coefficient of 7 × 10-5cm / cm / ℃ in plastic in the case of smaller. 3) Brittle temperature: PC solid sheet brittle transition temperature of -40 ℃, the minimum continuous use temperature of -30 ℃, is generally not comparable plastic. 4) Flammability: PC solid sheet is a flame retardant self-extinguishing plastic one, it does not produce toxic gases when heated to high temperatures. ULR-94 certification, flame retardant B1 level fire drops, no gas; 5) Thermal conductivity: PC solid sheet of thermal conductivity does not differ greatly and general plastic, glass 1/4 1/300 iron, aluminum 1/1000, 1/2000, is one of the excellent insulation properties of the material such as copper. c, the optical properties of 1) transmittance: PC solid sheet of light transmittance of 88% and a glass quite. 2) Weather resistance: general long-term exposure to outdoor PC endurance plate, by ultraviolet radiation can lead to yellowing and surface degradation. Czech anti-PC sheet surface with a layer of anti-UV layer, even if long-term exposure to outdoor, optical and mechanical properties did not change significantly. d, noise performance: Czech resistance to the effect of noise is higher than the PC sheet glass 3-4DB, is currently the preferred material for highway noise barriers. e, light weight: Under the same thickness and area, PC solid sheet is only half the weight of glass, so you can save a lot of handling and construction difficulty and shipping.
