Process for preparing fiber reinforced polyvinyl chloride composition and products

A process for preparing a fiber reinforced thermoplastic, the process comprising:

• melting a first thermoplastic and a second thermoplastic in a melting zone of a twin-screw processor, wherein the first thermoplastic is un-plasticised polyvinyl chloride (u-PVC) and the second thermoplastic is acrylonitrile-butadiene-styrene (ABS);
• feeding at least one continuous fiber downstream of the melting zone into a melted mixture of the un-plasticised polyvinyl chloride (u-PVC) and the acrylonitrile-butadiene-styrene (ABS);
• incorporating the at least one continuous fiber into the melted mixture in a mixing zone, the mixing zone including at least one wave element having a continuous outer surface in the form of a helical wave, wherein the continuous outer surface of the wave element is formed by at least one crest and at least one trough in a direction parallel and perpendicular to an element axis to form the helical wave;
• and
• obtaining the fiber reinforced thermoplastic from the twin screw processor.
