Thermoplastic olefin composition, process for making the composition and method for negative vacuum forming articles therefrom

A process for female vacuum forming an article, comprising:

• mixing about 20 wt % to about 40 wt % polypropylene, about 30 wt % to about 50 wt % ethylene copolymer, and about 20 wt % to about 30 wt % linear low density polyethylene to form a blend, based upon a total weight of the blend;
• and
• forming a sheet from the blend;
• disposing the sheet in a mold;
• and
• vacuum forming the sheet into an article.

A thermoplastic olefin composition, comprising the reaction product of, based on the total weight of the composition:

• about 20 wt % to about 40 wt % polypropylene;
• about 30 wt % to about 50 wt % ethylene copolymer;
• and
• about 20 wt % to about 30 wt % linear low density polyethylene;
• wherein the polypropylene, the ethylene copolymer, and the linear low density polyethylene each have a melt index of less than or equal to about 1 g/10 min. measured at 230° C., employing a 2.16 kg weight.
