SPC flooring: Stone Plactic ComPosite is also short for hard PVC flooring sheet SPC floor is produced by conical twin-screw extruder, through three or four roll calender, laminating PVC color film, PVC wear-resistant layer and PVC substrate at one-time. The process is simple, easy to operate, the lamination is completed by heat, no glue is needed. SPC stone plastic floor, is based on high-tech development of a new type of environmental protection floor, with zero formaldehyde, mold, moisture, fire, insect prevention, simple installation and other characteristics. SPC floor material uses environmental protection formula, and it does not contain heavy metals, phthalates, formaldehyde and other harmful substances, which is in line with EN14372, en649-2011, IEC62321, gb4085-83 standards. In Europe, the United States and the asia-pacific market, it is widely popular. With its outstanding stability and durability, stone plastic floor has solved the problem of real wood floor being affected by damp, deformation and mildew, and solve the formaldehyde problem of other decoration materials. It can choose many design and color patterns, suitable for indoor decoration, hotels, hospitals, shopping malls and other public places. Gwell special technology can meet the requirements of SPC floor synchronous pattern production, shrinkage after tempering treatment: , shrinkage without tempering treatment: (shrinkage test standard: 80, standard for 6 hours)
