SuperLite thermoplastic composite sheets, made by a modified paper making process, are a highly adaptable form of chopped glass reinforced resin that may be easily molded over a wide range of density to provide the required balance of properties for a host of applications. Relatively high glass fiber content is used to effect lofting, the tendency of the product to form a porous, low density structure with excellent insulating and flammability characteristics, depending on the particular resin, temperature and glass fiber content and molding pressure. Relatively high glass fiber content and low melt viscosity resin at the intended use or processing temperature are paired to maximize lofting. The resulting network tends to exhibit superior sound dampening properties, thermal insulation and fire performance without the use of halogen or heavy metal salts, while also providing high mechanical properties in a relatively easily moldable form. Resins such as polyetherimide (PEI) and polyphenylene sulphide (PPS) provide a superior balance of properties with outstanding flame resistance, stiffness, temperature capability and chemical resistance.
