Polycarbonate (PC) sheet series: a new high-strength, heat, light, lightweight construction materials are widely used in the production of light boxes, hood lighting, highway guardrail, signs, canopy lighting, industrial plants, greenhouse greenhouses, observation window, the sound barrier, exhibition lighting, advertising light boxes, PC board two types - solid as a solid sheet, hollow hollow plate or solar panels. Category: PC board is generally single plate and double plate, in addition there are plywood, wave-shaped plates and films. Color: Clear, blue, green, white, brown, gray. Uses: interior decoration, building lighting engineering, agricultural greenhouses, airports, railway stations, public bus stations, advertising signs, light boxes, industrial thermoforming products. Optical properties: light transmission rate of 50-92%. Impact resistance: impact resistant PC board 200 times the energy of the same thickness of ordinary glass, plexiglass for 30 times. Weathering Performance: PC board can maintain the stability of the physical indicators in the range of -40 ℃ to 120 ℃. Anti-condensation properties: the outdoor temperature is 0 ℃, the indoor temperature is 23 ℃, indoor relative humidity below 80%, non-condensing inside surface of the material. Flame retardant: the national standard GB50222-95 confirmation, PC board for the flame one level, ie B1 level. Sound insulation performance: Under the same thickness condition, solar panels to improve sound insulation than glass 3-4DB.
