  • Publication number: 20220347908
    Abstract: Mineral-filled polymer compositions and methods of forming such polymer compositions into a thermally stable article are provided. Methods of forming a polymeric article include providing a polymer composition comprising a crystallizable polymer, a mineral filler in an amount of more than about 15 wt-% based on the total weight of the polymer composition, and an impact modifier, wherein the polymer composition is at a temperature less than a crystallization temperature of the crystallizable polymer. The methods further include disposing the polymer composition in a mold, forming the polymer composition into an article within the mold, and releasing the article from the mold. The methods can include thermoforming the polymer composition in a mold, or injection molding the polymer composition in a molten form in a mold.
