Force plate has the characteristics Hazardous Substances in Electnical and Electronic Equipment, electrical and electronic equipment that restrict the use of certain hazardous substances, also known as 2002/95 / EC Directive an impact resistance: the greatest impact polycarbonate panels can be achieved 3kg / cm, the impact strength of PC sheet is 250-300 times that of ordinary glass, acrylic sheet is 20-30 times, twice tempered glass, almost no risk of fracture. With 3kg hammer to fall below two meters and no cracks, there is "no broken glass" and "ring of steel" reputation. 2, the transparent: excellent light transmittance of 75 ~ 90%, while its transparency may be comparable with the glass. In the sunlight does not produce yellowing, fogging, poor light transmission. UV coated plate in the sunlight prolonged sun exposure does not produce yellowing, fogging, poor light, the loss was only after a decade translucent 6%, PVC turnover rate is as high as 15% -20%, the glass fiber is 12 % -20%. 3, weather resistance: The surface layer co-extruded UV resin fatigue prevents UV-induced yellowing sunlight. Surface layer co-extruded with a chemically absorb UV and converted into visible light, photosynthesis of plants have a good stabilizing effect. Outdoor guaranteed years without fading. In the range of -40 ℃ to 120 ℃ to maintain the stability of the physical indicators. Artificial weathering test 4000 hours, yellowing of 2, to reduce the transmittance value is only 0.6%. 4, flame resistance: solid sheet itself is not spontaneous combustion and having the self-extinguishing. EU ROHS Directive and the stringent UL safety specifications, UL94 V0 class fire rating, V2 level, HB level. PC board itself ignition is 580 degrees Celsius, away from the fire self-extinguishing, does not produce toxic gases when burned, will not contribute to the spread of fire. 5, heat resistance, cold resistance: -40 ℃ to + Celsius do not cause quality deterioration deformation temperature 120 ℃ range. PC board does not occur at -100 ℃ cold crisp when not soften at 135 ℃, in the harsh environment there was no significant change in its mechanics, mechanical properties. 6, light rigid: light weight, only half of the glass, acrylic plate 1/3, good adaptability and safety, ease of handling, drilling, cut off installation, easy to break, easy construction process. 7, bendable: according to design using cold-formed at the site, the installation arched, semi-circular roof and windows. The minimum bending radius is 175 times the thickness of the plate used, also bending. 8, noise: PC board insulation effect is obvious, there is a better sound insulation than the same thickness of glass and acrylic plate, under the same conditions thickness, PC board insulation than glass to improve 3-4DB. Is the preferred material for highway noise barriers in the international arena. 9, energy efficiency: 夏天保 cool winter insulation, PC boards have a more lower than the ordinary glass and other plastic thermal conductivity (K value), the heat insulation effect of 7% -25% higher than the same glass, PC board heat insulation the highest 49 percent. So that heat loss is greatly reduced, and used to warm the equipment building is environmentally friendly materials. 10, anti-condensation: the outdoor temperature is 0 ℃, the indoor temperature is 23 ℃, indoor relative humidity below 80%, the inner surface of the material, non-condensing.
