Abstract: The thermoplastic polyurethane compositions described herein have very good recovery properties, rebound resilience, or both, while also having good softness (i.e. low hardness). It has been difficult to provide thermoplastic polyurethane compositions with this combination of properties. Some compositions described herein also provide low haze and/or good clarity properties. These combination of properties make the thermoplastic polyurethane compositions described herein useful materials for application that require fast recovery, good rebound resilience, or both while also requiring soft materials, and in some embodiments low haze and/or good clarity.

Abstract: The present invention relates to printing blankets, pipe liners, conveyor belts, inflatable articles, collapsible containers, protective clothing, and other types of coated fabrics that are manufactured with a thermoplastic block copolymer (TBC). This TBC can be a thermoplastic polyurethane (TPU), a copolyester (COPE), a copolyamide (COPA) or a polyurethaneurea (TPUU). The subject invention more specifically discloses a printing blanket or printing sleeve and a cured in place liner for a passageway or pipe. The TBC is (I) the reaction product of (1) a hydrophobic polyol or polyamine, (2) a polyisocyanate or an aromatic dicarboxylic acid, and (3) a linear chain extender containing 2 to 20 carbon atoms, or (II) the reaction product of (1) a hydrophobic polyol or polyamine, and (2) a carboxyl terminated telechelic polyamide sequence.

Abstract: The present invention discloses a thermoplastic polyurethane which is comprised of the reaction product of (1) a hydroxyl terminated polyester intermediate, (2) a polyisocyanate, and (3) a glycol chain extender; wherein the hydroxyl terminated polyester intermediate is comprised of repeat units that are derived from 1,3-propylene glycol and a dicarboxylic acid; wherein the hydroxyl terminated polyester intermediate has a number average molecular weight from 500 to 10,000; and wherein the thermoplastic polyurethane includes hard segments that are the reaction product of the polyisocyanate and the glycol chain extender. This thermoplastic polyurethane is unique in that it has a greatly reduced tendency to bloom. This is highly desirable in applications where high clarity is desired because blooming causes articles containing the thermoplastic polyurethane to be hazy or foggy in appearance.
