quality control in wood plastic composites

Modifiers for Wood Plastic Composites (WPC) - BYK Additives ....Wood Plastic Composites (WPC) belong to a group of natural fiber-reinforced compounds in which wood fibers (or wood flour) are used as reinforcing fillers in amounts generally ranging from. 50 to 80 %. A number of other natural fibers can be used for comparable applications, for example, hemp, flax, sisal, and coconut...

Wood-plastic composites in the United States : the interfacing of two ....Description. The term wood-plastic composites refers to any composites that contain wood (of any form) and thermosets or thermoplastics. Thermosets are plastics that, once cured, cannot be melted by reheating. These include resins such as epoxies and phenolics, plastics with which the forest products industry is most...

Wood Plastic Composites - A Primer - University of Tennessee ....on-site to make attractive patterns. WPC is touted as having envi- ronmental benefits, because it is made from residues (wood) or re- cycled materials (plastic). However, virgin plastics are commonly sup- plemented in WPC operations to maintain tighter quality control and offset highly fluctuating recycled plastic inventories.
