Wood-plastic composite - Wikipedia

wood-plastic composites (wpcs) are composite materials made of wood fiber/wood flour and thermoplastic(s) In addition to wood fiber and plastic, wpcs can also contain other ligno-cellulosic and/or inorganic filler materials. wpcs are a subset of a larger category of materials called natural fiber plastic composites (NFPCs), which may contain no cellulose-based fiber fillers such as pulp fibers, This type of wpc is different than the wpc decking and is not intended for outdoor usage.

Wood-Plastic Composites: Weathering Quality Issues : Plastics

1 Sep 2005 Not the wood-plastic composite (wpc) manufacturers because the materials were too new on the market. In Europe, wood and natural-fiber composites are far more varied and technically advanced. In this process, Pallmann's Palltruder first pelletizes wood flour or fiber and virgin or recycled HDPE. CreaFill fibers Corp., a supplier of cellulose fibers, reported in Madison on development of a composite prepreg made out of 60% cellulose fiber with 40% PTT

Sustainable wood-plastic composites from bio-based polyamide 11

wood-plastic composites from bio-based s and wood fibers (bio-wpc) provide an improved sustainability and carbon (PE), polypropylene (PP) or polyvinylchloride (PVC), and wood flour or fibers mainly from softwood like spruce or pine [2], [3], [4]. . by a dissolution of cellulose or hemicellulose components, which shifted the peak position to a lower wavenumber [26]. . This qualitatively indicates a better fiber/matrix adhesion due to the chemical treatment of the fibers.

JELU has been processing natural fibres for more than 100 years

We are a mid-sized company that has been managed by the Ehrler family for more than two generations. He bought wood shavings from the surrounding sawmills and processed these into fine wood flour, which was used Since then, cellulose fibres have been processed and marketed under the JELUCEL product line. JELU-WERK developed its own production facility and has since been producing wpc granulate, which is suitable for extrusion and injection moulding alike.
