Wood plastic composite is a relatively new material that has many potential uses. The markets for WPC decking lumber have been expanding recently and . compounded above the melting temperature of the thermoplastic polymers and then.
Essentially, composite decking boards are comprised of a mix of recycled wood fibers . It's this fusion that gives composite decking its inherent strengths such as lower . because wood will begin to degrade at the high temperatures required.
Wood-plastic composites also reduce energy use, since they melt at lower temperatures than typical plastics. Perhaps most recognizable as decking materials,.
