Wood plastic composites have gained relevance in recent years as an alternative to wood boards. However, because the cavities in wood fibres are compressed by high processing pressure during the extrusion of wood plastic composites, the product densities show a range of up to 1.5 g/cm3 depending on wood content..
Strandex has been developing extruded wood composites using wood fiber, high density polyethylene plastic resin, and other additives since the late 1980's. There are few companies in the composite industry today that have been around as long, or have experienced our level of success! Put our years of experience to..
Wood Plastic Composites (WPC) comprise a broad range of melt-processable composite materials that contain varying quantities of plastics, fillers and wood fibers, or other types of natural . Baerlocher offers an extensive portfolio of additives for the extrusion of wood-polyethylene and wood-polypropylene composites

Coextruded wood-plastic composites (WPCs) with glass-fiber (GF) filled shells were manufactured, and their thermal expansion behavior was studied. A three-dimensional finite element model (FEM) considering differential properties of both shell and core layers was developed to predict the linear coefficient of thermal..
This paper is intended as a introductory pedagogical tool for discussing the basics of wood plastic composite extrusion. Keywords: Extrusion, wood, thermoplastic, composite, extruder,. Introduction and Background. The manufacture of wood filled polymer materials has been an industrial process for about 80 years. Most
Wood plastic composite from JELU: WPC granulate for conventional plastics processing machines
When it comes to processing techniques, wood-plastic composites behave similar to any other plastic. During foaming, extrusion and injection molding, wood-plastic composites are compatible with existing machinery. For injection molding, the above considerations should be taken into account regarding gate size and..
