Abstract:
1. A soft touch thermoplastic olefin composition, the composition comprising: a polypropylene-ethylene copolymer having from about 3 to about 50 weight percent ethylene, a 1% flexural secant modulus from about 10,000 psi to about 40,000 psi, and having a melt flow from 0.01 to 500 dg/min and melting point from 115° C. to 160° C., and a cross-linked or uncross-linked ethylene-propylene thermoplastic elastomer, the thermoplastic elastomer being present in an amount from about 5% to about 40 percent of the weight of the soft touch thermoplastic olefin, wherein the soft touch thermoplastic olefin composition has a 1% flexural secant modulus from about from about 10,000 psi to about 80,000 psi and a Maximum Shore A hardness is from about 80 to about 100 and the compression set is from about 67% to about 100%.
