Abstract: Lubricious thermoplastic articles are formed from thermoplastic compounds including (a) thermoplastic elastomer selected from thermoplastic polyurethane, polyether block amide, and combinations thereof; and (b) from about 5 to about 20 weight percent, by weight of the compound, of hydrophilic water-insoluble polymer selected from polyolefin-polyoxyalkylene block copolymer, crosslinked polyvinylpyrrolidone, and combinations thereof. The thermoplastic compounds are capable of providing enhanced lubricity in the thermoplastic articles without significant degradation in mechanical properties such as elongation and tensile strength, as compared to thermoplastic articles formed from the neat thermoplastic elastomer and subjected to the same heat processing history.
