Polycarbonates used in engineering are strong, tough materials, and some grades are optically transparent and are easily worked, molded, and thermoformed. Because of these properties, polycarbonates find many applications. It is a unique engineering thermoplastic which combines a high level of mechanical, optical and thermal properties. The versatility of this material makes it suitable for many engineering applications. When extruded in multi-wall sheet form, it’s optical and impact properties in particular render this material an ideal Product for a wide range of roofing and glazing applications. Polycarbonate is a durable material with high impact-resistance, stronger and will hold up longer to extreme temperature. It is highly transparent to visible light, with better light transmission than many kinds of glass or FRP. Unlike most thermoplastics, polycarbonate can undergo large plastic deformations without cracking or breaking. As a result, it can be processed and formed at room temperature using sheet metal techniques, such as bending on a press brake. Even for sharp angle bends with a tight radius, heating may not be necessary. Multiwall polycarbonate is an extruded multi-wall polymer product, which is significantly lighter than glass, while managing to be stronger, more flexible, and more impact resistant. Multiwall polycarbonate is used most commonly for green houses, where it can support itself in a structurally sound configuration, limit the amount of UV light due to its nominal translucence, and can withstand the rigors of daily abuse in an outdoor environment. The stagnant air in the cellular space between sheets provides insulation, and additional cell layers can be extruded to enhance insulative properties at the cost of light transmission.
Application of Polycarbonate Sheet (Solid / Multiwall)
Multiwall Polycarbonate exhibits high degree of durability and toughness. Although single layer polycarbonate sheeting is more flexible than Multiwall configuration, it still retains significant advantages over alternative materials, including glass. A typical 6mm sheet has a density of 0.120 g/cm^2 and a thermal insulation R value of 1.77, while allowing 80% of visible light pass through. Standard Sheets of Multiwall manufactured in various colors and degrees of transparency, designed for use in most conventional roofing and glazing applications. Standard sheets are manufactured with different thicknesses, ranging from 4mm to 16mm.
