Do You Know the Properties of PVC Board

Manufacturing process

PVC is available in densities ranging from 3 pcf to 25 pcf (45 kg/m3 to 400 kg/m3). The raw materials are mixed together under controlled conditions and distributed into moulds. The flled moulds are then sealed, clamped shut and placed in a large press and heated. Once this process is complete, a solid piece of material emerges from the mould. The material is then expanded in a hot water bath to reach its final density and cured. The cured blocks are then cut into sheets of varying thicknesses according to customer requirements. The process and formulation combine to give the PVC its closed-cell nature and excellent physical properties.
