PC Solid Sheet What are the characteristics?
(A) the mechanical properties
1, the impact strength: PC Solid Sheet excellent impact resistance, it is 250 times higher than traditional glass, 30 times higher than the acrylic sheet.
Pc impact strength of polycarbonate panels like "transparent plate," said.
2, tensile strength, PC Solid Sheet heat resistance, even at 120 ℃, its tensile strength is still up 350kgf/cm2.
3, bending strength: PC Solid Sheet bending is good, even if the bending angle of 90 °, still broken.
4, anti-fatigue and creep resistance: PC Solid Sheet creep resistance in the thermoplastic plastic is best. Even at high temperatures the creep is still very small.
(B) the thermal properties
1, the melt-shaped temperature: PC Solid Sheet melt-shaped temperature 135 ℃, its continuous use temperature of 120 ℃.
2, the linear expansion coefficient: linear expansion coefficient of 7 × 10-5cm/cm / ℃ in plastic is smaller.
3, the brittle transition temperature: PC Solid Sheet brittle transition temperature of -40 ℃, the minimum continuous use temperature of -30 ℃, the plastic is generally not comparable.
4, Flammability: PC Solid Sheet one is a flame retardant self-extinguishing plastic, when heated at high temperatures does not produce toxic gases.
5, thermal conductivity: PC Solid Sheet thermal conductivity of plastics in general little difference, is the glass 1 / 4 iron, 1 / 300,
Aluminum 1 / 1000, copper 1 / 2000, is an excellent material for insulation.
(C) the optical properties
1, transmission rate: PC Solid Sheet light transmission rate of 85% or more with the glass quite.
2, weather resistance: general PC Solid Sheet material long-term exposure to outdoor, by ultraviolet radiation can lead to yellowing and surface degradation. PC Solid Sheet surface with a layer of anti-UV layer, even if long-term outdoor exposure, the optical and mechanical properties were not significantly changed.
(D) noise performance
PC Solid Sheet sound insulation than glass high 3-4DB, highway noise barriers is the material of choice. PC Solid Sheet has been light rail project in Tianjin, Wuhan, many cities and light rail construction noise barriers on the road use.
(E) Chemical resistance
Polycarbonate at room temperature for weak acid, weak base and alcohol resistance performance is good, but the strong acid, benzene, chlorinated hydrocarbons and esters resistance performance somewhat less apt to dissolve, swell or break down the phenomenon of . Because of its chemical resistance and low temperature, size and internal residual stresses on the length of exposure time, it should pay special attention before use
(F) and light weight
Under the same thickness and area, PC Solid Sheet glass is only half the weight, so you can save a lot of the difficulty of handling and shipping and construction
