| Résumé : |
Wood-plastic composites (WPC) are the combination of wood fibers, most commonly wood four waste, and a thermoplastic such as high density polyethylene (HDPE), polypropylene (PP), or PVC. The polymer content is generally 40-50% by weight. WPCs are extruded into profile shapes via continuous extrusion for the building and construction products industry as an alternative to wood and treated wood. Consumers are choosing WPC over wood, even though it costs more, because of lower maintenance requirements and aesthetic appeal. WPC does not require painting, resists warping and termite attack, and is generally resistant to moisture-related issues such as mold development. |
