four kinds of liquid solutions were used for fabricating wood polymer composites: sae 30 shell, netherlands and uk -lubricant oil, releasing agent airtech, usa , peg cell chemical, korea , and epoxy kuk-do chemical, korea . the peg is a condensation polymer of ethylene oxide and water with the general formula h och 2 ch 2 n oh, where the subscript n is the average number of repeating oxyethylene groups typically from 4 to 180. the low molecular weight compounds up to 700 are colorless
non-wood fiber segment accounted for the largest market in global natural fiber reinforced composites market. non-wood fibers include grass fibers, leaf fibers, bast fibers, fruit fibers, and st fibers. the market dominance of the non-wood fiber segment is due to the widespread applications of the bast fibers.

wood flour acts as a solid structure networked with the cross-linked polymer matrix. proceedings of the 51st international convention of society of wood science and technology november 10-12, 2008 concepción, chile paper ws-24 4 of 6 component of the composite, from the cross-linked polymer matrix.
thermoplastic polymers are preferred, as they allow easy processing of plastic/wood composites. the most common polymer matrices used are the polyolefins, such as pe and pp ashori, 2008; xanthos, 2005 . as can be seen from table 10.1, the majority of the work was done on wood flour/fibre and polyolefins. if compared with inorganic fillers, such as calcium carbonate the most abundantly used filler globally , which have proven effective at enhancing mechanical and physical properties of
wood polymer composites wpcs are materials made from wood, synthetic polymers, such as polyethylene pe and polypropylene pp , calcium carbonate caco 3 , and other additives .owing to their higher mechanical durability than wood, wpcs are used widely as feedstock for the manufacture of outdoor benches and floors, and an estimated 5.6 million metric tons were produced in 2019 .
wood plastic composites wood plastic composites wpc are defined as composite materials that contain thermoplastics and wood in various forms. from decking and cladding to fencing and garden furniture, wpc additives provide these applications with a long life span and minimal maintenance, giving advantages over solely wood-based materials.
wood contents typically range from 20 to 60% in these composites. additives to the composites will include processing aids lubricants, antioxidants, acid scavengers , and property enhancers biocides, couplin g agents, inorganic fillers, fire retardants, uv stabilzers, colorants, etc .
furthermore, aging of composites in mineral oil and evaluation of water uptake for wood plastic samples were performed. wood polymer composites have changed significantly after aging. the water diffusion coefficients were determined, and the significant influence of the amount of cellulose on the water absorption was shown.
wood-polymer composites wpc are materials in which wood is impregnated with monomers that are then polymerised in the wood to tailor the material for special applications. the resulting properties of these materials, from lightness and enhanced mechanical properties to greater sustainability, has meant a growing number of applications in such areas as building, construction and automotive engineering.
the more wood added to composite, the lower is the mfi of the final product. wpcs have the aesthetics of conventional wood combined with high strength. these factors have made wpcs a preferred alternative to conventional wood products. type insights. on basis of type, the market is divided into polyethylene, polypropylene, and polyvinylchloride.
