Abstract

See full text

A composition for making a composite plastics material, comprising a polymer, wood fibre and microsilica. The microsilica, i.e., silica fume, is added for the purpose of reducing the water absorption while maintaining, or improving, the flame retardancy, mechanical performance and processibility of the material. The intended polymers for the composite materials are polyethylene (PE), polyvinylchloride (PVC), polypropylene (PP) or polyethylene terephthalate (PET). The composites can be shaped through extrusion or heat-moulding.
