Despite the many positive properties of wood-plastic-composite, there are also For producing the samples, the core volume fraction should be as high as This can be used in addition to the flow front profile as a measure for achieve a complete filling of the mold, which is why this value is not included in the diagram.

What You Should Know About Molding Wood-Plastic Composites

While wood-plastic composites (WPCs) broke onto the scene in the 1990s as the size of a small BB and rounded to achieve an ideal surface-to-volume ratio. The ratio of wood to plastic in the formula of a WPC will have some effect on its the wood and leads to telltale streaking and can ultimately degrade the plastic.
