Talc composition and uses thereof

A process for reducing surface defects in a molded article comprising:

• providing a polymer composition comprising a polymer;
• and
• combining 35% to 45% by weight of a surface treated high aspect ratio talc (HART) with the polymer, based on the total weight of the polymer composition, to reinforce the polymer composition and reduce surface defects in the molded article;
• wherein the surface treated HART comprises from about 0.1% to about 10% by weight surface treatment agent and from about 0.1% to about 10% by weight dolomite and/or magnesite, based on the weight of the talc;
• and
• wherein the surface treatment agent consists of polymeric species comprising polyether and/or polyether modified polysiloxane.

A method for increasing the amount of talc in a functional composition to reduce surface defects in a molded article formed using the functional composition, the method comprising:

• providing a functional composition;
• and
• incorporating 35% to 45% by weight of a surface treated high aspect ratio talc (HART) into the functional composition, based on the total weight of the functional composition,
• wherein the surface treated HART comprises from about 0.1% to about 10% by weight surface treatment agent and from about 0.1% to about 10% by weight dolomite and/or magnesite, based on the weight of talc;
• and
• wherein the surface treatment agent consists of polymeric species comprising polyether and/or polyether modified polysiloxane.
