Wood-plastic composites (WPCs) do not corrode, and they and are highly resistant to rot, to decay, and to attack by the marine borer. . The addition of PRIEX coupling agents leads to improvement in mechanical properties as shown in the graphs below (75% wood fiber, 23% polypropylene, and 2% PRIEX coupling agent):
In this study, the effects of oxidized polypropylene, as a compatibilizer, and Nano-clay particles in improving the thermal properties of wood plastic composites are investigated. For this purpose, polypropylene polymer was oxidized in the vicinity of the air oxygen for 2 hours. Then, in order to produce the samples, Nano-clay..
Abstract. The low maintenance cost of wood plastic composite (WPC) is generating a boom in the market of wood composites products. An attempt is made to fabricate WPCs with saw dust of pine wood flour which is wastages of wood/furniture industry. These composites (WPCs) are made using matrices of recycled

The most common plastics used for WPCs are polyethylene (PE), polypropylene (PP), and polyvinyl chloride (PVC). The WPC blends can vary in percentage, with wood content up to 70%, but 50% wood/50% plastic is common. It was first thought that mixing plastic and wood together would result in plastic encapsulation of..
