wood plastic composite quality problems

Wood-Plastic Composites: Weathering Quality Issues : Plastics

Exterior wood-fiber composites like decks and rails haven't lived up to some of the early claims of long, maintenance-free life. In fact, composite decks with high wood loadings can shrink, expand, stain, warp, split, and fade much like natural wood. They can also grow mold and sprout mushrooms, be eroded by water, and 【Get Price】

Wood-Plastics Composites Done Right : Plastics Technology

Apr 26, 2012 Fines that pass through a 120 mesh screen are not desirable: These flow poorly and are difficult to distribute evenly in the plastic matrix. Poorly distributed wood fibers, called “wood spots,” are a common quality problem when the wood contains excessive fines or when the extruder is too worn to achieve 【Get Price】
