An extruded product having a foam core is formed by blending powdered cellulose with a base resin and an oxidizer to yield a first mixture. The first mixture is compressed, heated and extruded to form a pelletized compound which is compressed and heated into a homogeneous extrudable mixture. Moisture is extracted from the powdered cellulose at one or more points during the process to achieve a ...

Foam extrusion of PP-based wood plastic composites …

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/cm 3 depending on wood content and base material. Particularly in large-sized products, this may be ...

Quality control & profile control for film extrusion | Mahlo

In extrusion, solid to viscous materials - usually plastics - are melted and extruded under pressure through a shaping opening. The process is used for a variety of materials. Most frequently certainly in plastics processing, but also for composite materials such as fiber-reinforced plastics, WPC (Wood-Plastic-Composites) or thermoplastic polymers such as PVC, PP, PE, PET and PA.

In the foamed wood-plastic composites, the size was smaller, being in the range from 84 to 127 μm in the longitudinal direction and 90 to 137 μm in the transversal one. In the and recycled HDPE, the increase in size could be related to the expansion of cells caused by diffusion of the molten polymer gas into the nucleated cells.
