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.
describes compositions of wpc materials, including thermoplastics, cellulose fiber, minerals, additives, and their properties covers mechanical properties, microbial resistance, water absorption, flammability, slip resistance, thermal expansion-contraction, sensitivity to oxidation and solar radiation, and rheological properties of hot melts of wpc
mechanical and physical properties of wood plastic composites wpc , such as stiffness, strength, impact resistance, and density, play an important role in deciding the suitability of these products in various applications. recent advances in catalyst technologies for polymerization of polyolefin resins and process engineering have made wpc

wood plastic composites wpc are widely used in usa, the most common type of such panels are produced by mixing wood flour and plastics to produce a material that can be processed similar to 100% plastic-based products , , , . some of the major advantages of wpc include their resistance against biological deterioration for outdoor applications where untreated timber products are not suitable.
the composite typically consists of four major elements: wood flour, thermoplastic plastics, coupling agent, and lubricant. the physical and mechanical properties of wpcs highly depend on the material formulation, and the optimal material composition is an essential topic of current research.
wood-plastic composites are still new materials relative to the long history of natural lumber as a building material. the most widespread use of wpcs in north america is in outdoor deck floors, but it is also used for railings, fences, landscaping timbers, cladding and siding, park benches , molding and trim , window and door frames, and indoor furniture . 7
most of the physical and mechanical properties wpc depends mainly on the interaction developed between wood and the thermoplastic material. one way to improve this interaction is incorporating a coupling agent as additive. in general, the additives help the compatibility between hydrophilic wood and hydrophobic plastic allowing the formation
1. mechanical properties of lignocellulosic-plastic composites lpc were significantly affected by the characterizations of lignocellulose fillers in terms of chemical compositions and morphology. 2. wf addition resulted in reduction of tensile strength and thermal stability due to presence of xylan. 3.
plastic lumber and thermoplastic composites are sold as alternatives to wood products. however, many technical standards and scientific studies state that the two materials cannot be considered to have the same structural behaviour and strength. moreover, there are many compositions of thermoplastic
a new building material known as wood-plastic composites s has wpc emerged. wpcs are a combination of a thermoplastic matrix and a wood component, the former is usually polyethylene recycled or polypropylene, and the latter a wood processing residual, e.g. sawdust and wood shavings.
a wood plastic composite wpc is a common term referring to wood-based elements such as lumber, veneer, fibers, or particles that are combined with polymers to create a composite material. it is a broadly used term, and as such, wood elements can be combined with either thermosetting or thermoplastic polymers.

wood plastic composite wpc is a composite material made from sawdust and plastic as polymer bonding, that used in a variety of structural and non-structural applications. nowadays, in indonesia wpc is made from sengon sawdust and recycled hdpe plastic.
the tensile properties and impact strength of two 3d-printed commercial wood-plastic composite materials are studied and compared to those made of pure polylactic acid. relative to weight mechanical properties and the effect of the amount of fill on the properties are also determined.
