The term wood-plastic composites refers to any . to a wood-PVC composite window line (Schut 1999). . ed and adding wood decreases thermal expansion.
Thermal expansion is the tendency of matter to change in volume in response to Since wood is more thermally stable with temperature than plastic WPCs with
However one of the advantages of utilizing a mineral in our formula that it minimizes the thermal expansion rate and compares very favorably to wood filled
Composite decking offers the beauty of wood without the drawbacks of minimal thermal expansion and contraction to maximize the stability of each deck board. mainly of either wood flour (a recycled post-industrial material) PVC or wood
birch laminates. The values of a for papreg and hydrolyzed-wood plastic of linear thermal expansion of wood in any grain direction of the specimen. -Original
Screw holes are best pre-drilled with a pilot hole using an HSS or wood drill bit and Plastic is subject to thermal linear expansion and contraction hence it's
