WPC (Wood-plastic composite) pellets, WPC granules for WPC extrusion, injection

Wood plastic composite (WPC) pellets (granules) is a ready-to-use feedstock for extrusion of WPC decking & lumber profiles or injected items. One just needs WPC extruder, injection or pressing machine to process into WPC products.

Typical WPC composition includes recycled or virgin polymer (or their mix), natural filler (wood flour or other cellulosic powder)) and chemical additives.

Among extrusion WPC pellet grades we offer the most common compositions are as follows:

  • Recycled/virgin PE/PP + wood powder + mineral filler (in some formulas) + chemical additives + pigments (if needed).
    PE/PP WPC pellets are intended for extrusion of outdoor WPC profiles of different colors that are usually finished using sanding, brushing, embossing and other techniques.
  • Virgin PVC + wood powder + mineral filler + chemical additives + pigments (if needed).
    PVC WPC pellets are normally intended for extrusion of indoor profiles of different colors. They can come in single color or mixed so that natural wood grain appears on the surface. If needed, these profiles can be treated in many different ways (brushing, embossing, hot stamping, lamination and so on). Depending on formulation and treatment these profiles can also be used outdoors.
