Wood Plastic Composites


  • Finished product has a lower water absorption

  • Reduced power consumption

  • Improved extruder output

  • Reduced processing temperature

  • Increased melt strength

  • Prevention of edge tearing

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 fibers.

The material has exceptional mechanical properties, high dimensional stability, and supports the manufacture of complex profiles.

WPC based on polyolefins (HDPE, PP) are typically processed by means of direct extrusion and injection molding, while PVC-based WPC are processed using direct extrusion, co-extrusion or pressing technology.

Baerlocher offers an extensive portfolio of additives for the extrusion of wood-polyethylene and wood-polypropylene composites.
The BAEROLUB range of one-pack lubricant systems was developed to make extruded profiles easier to process, and to improve the quality of their surface.
