Use of Specialty Minerals In WPCs To Grow

New processing and formulation technologies are launching the second generation of wood-fibre plastic composites, which will increasingly use select minerals and long fibres, according to a report by Principia Partners.

In North America the demand for WPCs has been growing at a rate of 25% annually since 1998. Initially these products were made mostly from recycled plastic and recycled wood, but in recent years there has been a trend to more and more sophisticated formulations. Minerals such as calcium carbonate and clays are increasingly being used in WPCs to provide lubricity and absorb water. Additionally, there is growing use of additives such as borates and alumina hydrate as flame retardants in WPCs, as well as increasing use of long fibres to improve structural performance.
