At present, in the field of decoration, indoor deck paving materials are generally all kinds of wood decking or composite wood decking. Wood decking feel more comfortable, but in use often appear expansion deformation, warping cracking and other issues. The wpc decking is a new type of environmental protection plastic-wood composite product, which is mainly composed of wood flour plant fibers, thermoplastic polymer materials and processing aids. It is made of high-tech green environmental protection materials which are mixed evenly and then heated and extruded by die equipment. It has the properties and characteristics of wood and plastics. It is new environmentally friendly high-tech materials for plastics and can replace wood and plastics.

With the development of the times, the demand for some special deck is also growing, such as basketball deck. Basketball deck requires good anti-skid performance and cushioning performance, while the existing conventional wpc deck has poor elasticity, poor adhesion, and is prone to aging, cracking and wear. The elastic co-extrusion wpc profile and its preparation method have good elasticity and adhesion, and are not easy to aging and cracking and wear-resistant.
