PVC foam board is organic and inorganic combination of the preparation through the series of advanced technologies, the extrusion foam molding, a wood-plastic sheet, extrusions, bar. As the use of the raw materials and production processes do not use glue bonding, no formaldehyde, benzene, ammonia, trichloroethylene, and other harmful substances. And has anti-UV, coloring good performance, heat insulation, noise, acid and alkali resistance, insulation, fire-retardant, anti-corrosion, anti-mildew and anti-pest, moisture resistance, sawing, planing, nails, a good machining performance, and 100% recovery, is a jewel instead of the traditional green timber new material. Compared to PVC free foam sheet, PVC crust foam board has the better advangtages on hardness, cleaning, strength and so on.
