The changes such as foaming, solidification, modified, the characteristics such as density, intensity to change Wood-plastic material may also reach up anti-aging, anti-quiet
The particular/special requirements such as electric, fire-retardant；It is good with ultraviolet stability, coloring：Its great advantage is exactly to turn waste into wealth, and can
100% reclaiming is produced, and can be decomposed, will not be caused " white pollution ", be real green product；Raw material sources are extensive：
The plastic raw materials for producing wood plastic composite are mainly high density polyethylene (HDPE) or polypropylene, and wood fibre can be wood powder, cavings
Or wood-fibred, further need exist for a small amount of additive and other processing aids；Can be as needed, arbitrary shape is made and size is big
It is small；
Currently, in order to improve its hardness, a variety of fillers are often added in Wood-plastic material wherein, then these inorganic fillers and plastics
The compatibility of matrix is relatively low, is easy to cause the stability of finished-product material and reduces.
