Specification

PC board also named as polycarbonate plate, the substrate is polycarbonate (Polycarbonate), English name abbreviation of PC

Appearance: a variety of colors,less crystal points,high light transmittance, high finish, good flatness

Impact resistance: the impact of the endurance board can reach up to 3kg / cm, PC impact plate impact strength is 250-300 times than the ordinary glass, is 20-30 times than the acrylic plate, is 2 times than the tempered glass, almost no fracture dangerous. With a 3kg hammer to fall from following two meters also no cracks, so it has a reputation of "bulletproof glass" and "ring steel" .

 
Transparency: excellent light, light transmission rate up to 75 ~ 90%, and its transparency can be comparable with the glass. In the sun exposure will not produce yellowing, atomization, poor light transmission. UV coating plate in the sun burst will not produce yellowing, atomization, poor light transmission, ten years after the light loss is only 6%, PVC loss rate is as high as 15% -20%, glass fiber is 12 % -20%.

 
Weatherability: the surface have the UV-resistant co-extruded layer, it can prevent the sun caused by UV resin resin fatigue yellow. The surface coextrusion layer has a chemical bond to absorb ultraviolet light and convert it into visible light, which has a good stabilizing effect on plant photosynthesis. Outdoor can guarantee ten years does not fade. In the -40 ℃ to 120 ℃ range to maintain the stability of the physical indicators. Artificial climate aging test 4000 hours, the yellowing degree is 2, light transmittance reduction value of only 0.6%.

Flammability: The impact plate itself is not self-igniting and has self-extinguishing. In line with the EU ROHS directive and strict UL safety standards, UL94 fire rating to V0 level, V2 level, HB level. PC board itself ignition is 580 degrees Celsius, self-extinguishing from the fire, burning will not produce toxic gases, will not contribute to the spread of fire

 
Heat resistance, cold resistance: It does not cause deformation and other quality deterioration in the temperature range of -40 ℃ to +120 ℃. PC board does not occur crisp at -100 ℃, not softened at 135 ℃, In harsh environments, its mechanical, mechanical properties were no significant changes.

 
Light hard: light weight, only half of the glass, acrylic plate 1/3, good adaptability and safety, easy handling, drilling, not easy to break when cut off, simple processing.

 
Plasticity: according to the design it can use cold-formed at the site, installed into the arch, semi-circular roof and window. The minimum bending radius is 175 times of the thickness of the plate ,it can also be hot-rolled.

 
Sound insulation: PC board sound insulation effect is obvious, than the same thickness of the glass and subgravity board has better sound insulation, under the same thickness conditions,PC board sound insulation can increased 3-4DB than glass. In the international arena, it’s the preferred material for highway noise barriers.

Energy saving: summer cool, winter insulation, PC board has lower thermal conductivity (K value) than ordinary glass and other plastic , insulation effect higher 7% -25% than the same glass, PC board insulation up to 49 %. So that greatly reduce the heat loss, mostly use for having heating equipment building, is environmentally friendly materials.

 
Anti-condensation: outdoor temperature is 0 ℃, indoor temperature is 23 ℃, indoor relative humidity less than 80%, the material inner and surface does not condensation.

Specification:thickness from 0.125mm to 12mm,the maximum width is 2.1 meters

Application            
All LED Light lens,such as led high bay light,street light,industrial light or other lighting products.
