VACUUM THERMOFORMED, EXTRUDED SHEETING WITH IMPROVED REDUCED GLOSS

摘要

The present invention is directed to an elastomer composition having at least two phases, one phase comprising a very low density polyethylene "VLDPE" component and another phase comprising a propylene polymer component wherein the propylene polymer component comprises at least one branched polypropylene and the VLDPE phase is continuous. Preferably, the VLDPE component has a melt tan delta between about 0.7 and 8 as measured by parallel plate rheometer at 0.1 radians per second, 180°C, and 10 percent strain; and the ratio of the melt tan delta of the VLDPE to the melt tan delta of the propylene component is from 0.5 to 4. The invention also provides a method of making such compositions, and to low gloss articles prepared from the same. The inventive compositions are particularly suitable for fabricating thermoformed sheeting with reduced gloss, most preferably employed as a skin in a composite interior automotive article comprising a shaped article and a negative thermoformed shaped skin or as non-carpet automotive flooring.
