Problems solved by technology

[0002] Polyvinyl chloride low-foaming board is a new type of environmentally friendly material developed in recent years that "replaces wood with plastic and steel with plastic". It is mainly used in advertising, bathroom cabinets and other industries. It was the first to introduce equipment and technology from Europe. , so the quoted product standards also refer to European standards. The density of the plate is relatively high, and the 1-5mm thin plate is generally greater than or equal to 0.6g / cm 3 , the density of the plate above 5mm is ≥0.55g / cm 3 In recent years, with the development of domestic equipment and processing technology, especially additives, the density of the board has been greatly reduced, which can reach 0.4-0.45g / cm 3 Between, thus greatly improving the application space of the board, reducing the cost of use, but there is still room for reduction in its density
