Polycarbonate (PC) series board polycarbonate (PC) series board: is a new type of high strength, heat insulation, light transmission, portable building material, widely used in lamp box production, car roof lighting, highway guardrail, explosion shield, lighting curtain, industrial plant, greenhouse, observation window, sound barrier, exhibition lighting, etc., PC board is divided into two kinds - solid endurance board, empty. The center is a hollow board or sunshine board. Category: PC boards are generally single-layer and double-layer boards, in addition to multi-layer boards, wave-shaped boards, thin films. Colour: transparent, blue, green, Milky white, brown, grey. Uses: Indoor decoration, building lighting engineering, agricultural greenhouse greenhouse, airport, railway station, public bus station, advertising street sign, light box, industrial thermoforming products. Optical properties: transmittance of 50% to 92%. Impact resistance: The impact energy of PC board is 200 times as much as that of ordinary glass with the same thickness and 30 times as much as that of plexiglass. Weather resistance: PC board can maintain the stability of various physical indicators in the range of -40 ~120 ~C. Anti-condensation performance: When the outdoor temperature is 0 C, the indoor temperature is 23 C, and the indoor relative humidity is below 80%, the inner surface of the material does not condensate. Flame Retardant Performance: The national standard GB50222-95 confirms that the sunshine panel is the first level of flame retardant, namely B1 level. Sound insulation performance: Under the same thickness conditions, the sound insulation capacity of sunshine panels is 3-4DB higher than that of glass. Processing performance: Single-layer PC board can be processed by vacuum forming and pressure forming. Double-layer PC board can also be cold-formed at room temperature. Light weight: the weight of single-layer PC board is 1/2 of the same thickness glass; the weight of double-layer PC board is 1/5 of the same thickness glass. Thermal performance: Under the same thickness, PC board can save energy compared with glass, plexiglass and other materials.
