Wood-plastic composites (WPCs) are composite materials made of wood fiber/wood flour and thermoplastic(s) such as PE, PP, PVC, or PLA.

The wpc decking products adopts a scientific and efficient production technology and enjoys an extensive technology extension. It is a project that utilizes the comprehensive development of waste resources and turns waste into treasure. The material can be sawed, cut, planed, nailed, and the performance of the product can be compared with hardwood products. The wood plastic product has stiffness and toughness, which can withstand static load and movement. The cost performance of wood plastic product is significantly better than other pure plastic or pure wood products.

Wood plastic composite products are still new materials relative to the long history of natural lumber as a building material. The most widespread use of WPCs in North America is in outdoor deck floors, but it is also used for railings, fences, landscaping timbers, cladding and siding, park benches, molding and trim, window and door frames, and indoor furniture. Manufacturers claim that wood-plastic composite is more environmentally friendly and requires less maintenance than the alternatives of solid wood treated with preservatives or solid wood of rot-resistant species. These materials can be molded with or without simulated wood grain details.

Sundi has the whole range of WPC products including decking, railing, pergola, etc., both co-extruded and general type.
