Wood-plastic composite (WPC) material

WPC is one of the new composite materials, which is popular both domestically and overseas in recent years. The adoption of polyethylene, polypropylene and polyvinyl instead of the usual resin adhesives, which are mixed with wood-dust, rice husk, straw and other waste plant fiber, to be process by pressing modeling, injection or other plastic making method, finally the new building materials are made. This kind of material is mainly used in the industries of building, furniture, logistic packaging. This kind of material processed in this technology is named as WPC boards.

Main characteristics
wood plastic composite material is based on the high-density of HDPE and woodiness fiber, which endows it with both the characters of plastic and wood.
1) Easy processing
WPC was composited by fiber and plastic. Therefore, it owns the similar processing character with wood. It can be sawed, nailed, planed and all those processing can be done by common woodworking tools. Meanwhile, the nail-holding power is obviously superior than other composited material. The mechanical performance is also better than wood material. The nail-holding power is3 times of common board and 5 times of the planed board.

2)Outstanding strength
WPC contains plastics, which gifts it good elasticity modulus. Meanwhile, with the fiber component fully mixed with plastic, it owns the physical mechanical characters of hardwood compression endurance as well as bending endurance, thus the endurance of it is much superior to the normal wood. The surface hardness of WPC is normally 2-5 times of the common wood.

3)Water resistance, corrosion resistance and long-lasting
Compared with the natural wood, WPC and WPC products are high acid-resistant, water-resistant and corrosion-resistant. Moreover, it is never bacteria growth, no moth-eaten and no fungi living. It is long lasting for a more than 50 years’ lifetime.

4)Well adjustable performance
With additive, plastic will be polymerized, foamed, solidified, thus changing the density and strength of the WPC. Meanwhile, it could also satisfy the anti-aging, anti-static and flame retardant requirements.

5)UV light stability and good color

6)The biggest advantage of WPC is reusing the waste and 100% available for reproduction. All material can be dismissed and no “white pollution”. It is one true green environmental friendly product.

7) Wide raw material sources
The main plastic material for wood plastic composite material is high-density polyethylene or polypropylene. Woody fibers can be wood powder, grain husk or other wood fibers. Meanwhile, a small amount of additives and other processing agent are needed.

8)Various shapes and sizes can be produced as required
With the development of wood plastic composite material, the main plastic raw material for WPC making, is not only high-density polyethylene or polypropylene, but also PVC and PS. Moreover, the processing method is changed from single-screw extruder to the second generation of conical twin-screw extruder, then by the initial parallel twin-screw extruder granulation, and then by tapered screw extruder, which can change the plasticity, aging, creep, single color and poor resistance and poor tensile strength characteristics.
