8mm to 20mm Thickness Polycarbonate Four Wall Hollow Sheet/PC Sheet

polycarbonate sheet product Features:
(1) translucent: P C plate light transmittance of up to 89%, glass phase deceased mother with the United States. UV coated plate in the sun, prolonged sun exposure does not produce yellowing, fogging, poor light transmission, light transmission loss was only after ten years 6%, PVC turnover rate is as high as 15% -20% glass fiber 12 % -20%.
(2) impact resistance: impact strength is 250-300 times that of ordinary glass, 30 times that of same thickness of acrylic sheet is tempered glass 2-20 times, with two meters below 3kg hammer falling and no cracks, "broken glass "and" ring of steel "reputation.
(3) UV: PC board side coated with anti-ultraviolet (UV) coating on one side with anti-condensation process, set UV, heat insulation anti Dettol functions in one. Can block ultraviolet rays pass through, and for the protection of precious works of art and exhibits, making it from UV damage.
(4) Light weight: accounts for only half of the glass, saving transportation, unloading move, the cost of installing and supporting frame.
(5) flame retardant: the national standard GB50222-95 confirmation, PC board for the flame level, ie B1 level. PC board's own ignition is 580 ºC, away from the fire self-extinguishing, does not produce toxic gases when burned, will not contribute to the spread of fire.
(6) can be bending: Keyi design using cold-formed at the site, the installation arched, semi-circular roof and windows. Minimum bend radius is 175 times the thickness of the plate using, also bending.
(7) Sound insulation: PC board noise effect is obvious, there is a better sound insulation than the same thickness of glass and Acrylic panels, in thickness under the same conditions, PC board to improve sound insulation than glass 3-4DB. Highway noise barriers is the material of choice in the international arena.
(8) Energy conservation: Xia Tianbao cold, winter insulation, PC board has more than ordinary glass and other plastic thermal conductivity (K value), thermal insulation effect of 7% -25% higher than the same glass, PC sheet spacer heat up to 49%. So that heat loss is greatly reduced, and used to warm the equipment building, an environmentally friendly material.
(9) temperature adaptability: PC board does not occur at -40 ºC cold crisp when not soften at 125 ºC, in the harsh environment no significant change in its mechanical, mechanical properties.
(10) weather resistance: PC board can maintain the stability of the physical indicators in the range of -40 ºC to 120 ºC. Artificial weathering test 4000 hours, yellowing degree 2, light transmission rate decreased value of only 0.6%.
(11) anti-condensation: the outdoor temperature is 0 ºC, the indoor temperature is 23 ºC, indoor relative humidity below 80%, the inner surface of the material non-condensing.
 (12) To add to anti-aging UV coating can be the acid and alkali resistance.
