The present invention is directed to improved processes for making plastic articles, and articles made therefrom. In a broad aspect, the invention is directed to improved processes and articles made therefrom, that include the steps of providing as separate materials a first material that includes a polyolefin, a second material including an admixture of from about 45 to 85 wt. % of the total admixture of at least one particulated mineral filler; and from about 15 to 55 wt. % of the total admixture of at least a second polyolefin having a melt index greater than about 150 g/10 min at 190&#xb0; C./2.16 kg, as measured per ISO 1133 (condition D); applying a shear force to form a molten blend; shaping the molten blend and solidifying the molten blend.

Thermoplastic articles and processes for making the same using an improved masterbatch

The present invention is a process for producing a thermoplastic foam sheet comprising contacting a molten monovinylidene aromatic or olefinic polymer with a physical blowing agent to form a polymer/blowing agent mixture, and foaming the mixture into a region of lower pressure within a sheet extrusion line, wherein the extrudate is pulled and compressed to form a thermoplastic foam sheet having a uniform thickness.
