3mm 4mm 5mm 6mm 8mm 10mm 12mm Clear Scratch Resistant Transparent 4 X 8 Feet Twin Wall hollow Polycarbonate Sheet PC hollow sheet for roofing and building material
Features:
Lightweight: Its specific gravity is only half that of ordinary glass, and it is not easy to break. It saves time and effort in transportation and installation, and is especially suitable for use in tall buildings.
Good light transmittance: The colorless and transparent polycarbonate hollow board can provide excellent transparency and surface gloss, while the colored board can block the stronger parts of the sunlight, making the passing light softer.
Excellent sound insulation performance: It can effectively reduce noise and is one of the preferred materials for highway sound barriers.
Thermal insulation and heat preservation: It has a lower thermal conductivity (K value) than ordinary glass and other plastics, which greatly reduces heat loss. It is used in buildings with heating equipment and is an environmentally friendly material.
Strong impact resistance: Polycarbonate (PC) is the thermoplastic with the best impact resistance. The hollow board made of PC can maintain good impact resistance for a long time within a relatively wide temperature range and is known as "unbreakable glass" and "sound steel".
Anti-condensation: Under normal circumstances, when the outdoor temperature is 0℃ and the indoor temperature is 23℃, as long as the indoor relative humidity is below 80%, the surface of the material will not condense.
Flame retardant and fireproof: It has excellent fire resistance. Tested by the National Fireproof Building Materials Supervision Center, it meets the GB8624-1997 standard and reaches the difficult-to-burn B1 grade. The ignition point of the board itself is 630℃. During the combustion process, it will not produce toxic gases, will not contribute to the spread of fire, and will self-extinguish after being removed from the fire source.
Good chemical resistance: It can resist the erosion of various organic acids, vegetable oils, neutral salt solutions, aliphatic hydrocarbons and alcohols at room temperature. However, polycarbonate sheets are soluble in chlorinated alkanes, slightly soluble in aromatic hydrocarbons and ketones, can be destroyed by alkali, and will swell in thinner and methanol.
Excellent weather resistance: The surface usually has a high-concentration UV co-extruded anti-ultraviolet layer, which can block ultraviolet rays from passing through, protect indoor objects, extend the service life of the board, and is less likely to cause yellowing, fogging and other phenomena due to long-term exposure outdoors
