TERMOPLASTKOMPOSITION OCH SETT ATT FORMA FOREMAL DERAV

摘要

The invention provides an improved method for producing a filler-loaded thermoplastic resin composite by mixing a thermoplastic resin with a filler, making it possible to be applied to molding machine such as extrusion and injection molding machines without the disadvantage of segregation between the resin and the filler otherwise inevitable leading to inferior uniformity of the shaped articles. The invention is characterized by the presence of a fibrillatable polytetrafluoroethylene during the mixing under mechanical shearing forces, wherein the thermoplastic resin is melted in one case and not melted in other case. The invention is also effective for shaping cellular foamed bodies of a filler-loaded thermoplastic resin with fine and uniform cellular structure.
