WPCs are a subset of a larger category of materials called natural fiber plastic composites , which may contain no cellulose-based fiber fillers such as pulp fibers, peanut hulls, coffee husk, bamboo, straw, digestate, etc.

Chemical additives provide for integration of polymer and wood flour (powder) while facilitating optimal processing conditions.

Nanjing Jieya compounding lines for making wood plastic pellet are customized  to the application: from material transfer and feeding to filling and reinforcement, devolatilization, pelletizing, conveying and packaging. With 20 year industrial experience,our twin screw extrusion lines enjoy a good balance of price and performance.
