What is an extrusion plate?
Extruded board, fully extruded polystyrene foam board, referred to as Extrusion board, also known as XPS board. The polystyrene resin and polymer are used to heat the mixture and inject the catalyst. Then, the rigid foam board with continuous closed cell foaming is extruded.
With high thermal resistance and low linear expansion ratio, the characteristics of the low, the obturator structure rate reached more than 99%, the formation of a vacuum layer, avoid air flow cooling, to ensure that the insulation performance of lasting and stable, relative to the closed cell foam polyurethane rate of 80%, the leading advantage is self-evident. Practice has proved that the insulation effect of 20mm thick XPS extruded insulation board is equivalent to that of 50mm thick foamed polystyrene and 120mm thick cement perlite. Therefore, this material is currently the best choice for building insulation.
