This time should be said that history is not long. In the 1970s, the real industrialization was also in the 1990s. When this material comes out, people call it "the wood of the future" and its chemical composition is polyvinyl chloride. Due to the wide application of rigid PVC low foaming products, it can replace almost all products made of wood. Has the ability to compete with wood.
The technology of rigid foaming has developed rapidly in recent years. The United States is very prominent in the development of rigid PVC foaming technology, with large investment and high output. Many new products have been developed to make rigid PVC foamed products in construction. In the field of decorative materials, furniture materials have been industrialized.
The processing technology of rigid PVC foam products has made rapid progress, and there are requirements for foaming in equipment, molds and formulation processes.
Wood flour or other fillers are added to the PVC foamed product, and different characteristics of the rigid PVC foamed product are imparted by adding different fillers. Improve the range of applications of this product in place of various building materials and decorative materials. At the same time, the surface of the rigid PVC foamed product is well decorated.
