what is wpc composite - select decking
the wood used in composite decking boards is sourced from reclaimed / recycled wood that has been discarded by modern industrial process & that thrown away after domestic use. this reclaimed wood is processed to produce a fine wood flour that forms the wood component of the wpc decking boards.
wpc board | features of wpc board | disadvantages of the wpc ...
the cost of the wpc material is higher compared to the other materials used for the same purpose. natural wood texture is lacking, due to the lack of natural wood feel when furniture or doors are made of this material. wpc consists of wood and plastic, so the deficiencies of both materials are also present in the wpc material.
process of replacing wood with new wpc composite material ...
a new wood plastic composite material, is generally referred to as wood-plastic composites (wpc).wpc is a new environment-friendly composite material, which is composed of recycled plastics (pe, pp, pvc, etc.) and wood fiber or plant fiber (such as wood powder, wood chips, wheat straw, rice husk, etc.) as reinforcing material or filler, and is compounded with other materials after pretreatment.
advantages and disadvantages of wpc boards | mccoy mart
wpc board disadvantages: wpc consists of both, wood and plastic so the shortcomings of both these materials are present in the wpc material too. the cost of wpc material is high compared to the other materials used for same purposes. wpc material doesn’t have the natural wood texture.

in addition, the extruder conveys the compounded wood–polymer mixture through the die. there are four primary types of extrusion systems used to process wpc profiles. these are the (1) single screw, (2) co-rotating twin screw, (3) counter-rotating twin screw, and (4) woodtruder™. single-screw extruder
prospects for growth in wood plastic composite markets – indufor
additionally, there is now budding innovation in the use of wpcs in core material in the sandwich injection molding process. the recycling of plastics has been adopted by many of the large wpc producers in the united states, with some producers accepting plastic donations and looking to establish commercial recycling partnerships.

processing temperatures are one of the few portions of the manufacturing phase where wood-plastic composites differ significantly from conventional plastics. wood-plastic composites generally process in temperatures around 50 degrees lower than the same, unfilled material. most wood additives will begin to burn at around 400 degrees fahrenheit.
extrusion - a continuous process, consisting in punching a material having a high viscosity in the liquid state, through a forming tool (die head) to obtain a product with a desired cross-sectional shape. in the industry of polymers extrusion is used from the 30-ies of the last century.
recycling material from wood-plastic composites - fraunhofer wki
recycling is principally divided into two variants; “internal recycling”, in which production residue i.e. relatively undamaged material is re-used during the manufacturing process, and “end-of-life recycling”, in which the objects are materially or energetically recycled following a certain period of use (see diagram).
