the market for the wood-plastic composite has grown and wpcs now are used in automotive applications, as well as in the building products sector of the economy. a wood-plastic composite is a blended product of wood, or other natural fibers, and a thermoplastic material.
the present invention is an improved wood-plastic composite wpc produced from a mixture comprising, wood particles, plastic, and optionally additives. the wpc of the invention further comprises an active ingredient that acts as a biocide. the active ingredient comprises tbba or a homologue or derivative thereof and is added to the mixture together with the wood particles during and/or before
an extruded composite adapted for use as a building material includes a core having a base polymer and a natural fiber in a substantially homogeneous mixture and an ionomer capstock. to improve adherence of the ionomer to a base polymer, the ionomer can be mixed with a similar or substantially similar base polymer prior to coextrusion with the core.
affordable 3d printing: new materials, new horizons. with costs decreasing and usability improving, together with the ability to print at ever finer resolutions in a fast-growing range of
provided is an eco-friendly wood plastic composite, which is applicable to plastic-based composite building materials, and shows improved mechanical properties, thermal properties and flame resistance. the polyolefin/wood composite capable of being used in the presence of clay added thereto comprises: 70-80 wt% of wood powder having a size of 50 mesh; 1-3 wt% of montmorillonite, a layered
the unlikely, eccentric inventor turning inedible plant life into fuel. marshall medoff unveils to 60 minutes his innovative method of turning plant life into fuel and other useful products
a wood-plastics composition is prepared from used or waste plastics, wooden fibres for modifying plastics, and resin compatibilizer through fusing and proportionally mixing. said resin compatibilizer is prepared from eva, acrylic acid or acrylate and polyvinyl chloride through mixing. its advantages are high strength toughness, and improved machinability.
the invention relates to a wood plastic composite material comprising the following materials in parts by weight: 100 parts of wood meals, 20-80 parts of waste plastics, 5-50 parts of waste rubbers, 10-60 parts of high-melt index thermoplastic resins, 1-12 parts of surface active agents, 2-8 parts of lubricating agents, 0.1-4 parts of cross-linking agents, 0.1-4 parts of antioxygens and 0.05-1
