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: A liner for repairing damaged pipes, such as underground sewer or gas pipes is disclosed. The liner comprises a TPU coating on a fibrous mat of non-woven fabric. The TPU coating is a high heat resistance polyester TPU which allows an epoxy resin/amine to be saturated in the non-woven fabric and the cure initiated by the use of steam or hot water. The cured epoxy resin converts the liner from a flexible state to a rigid state as the liner is cured in place inside the pipe. The TPU containing liner may also be used with thermoset resins other than epoxy resins, such as polyester resins and vinyl ester resins.

Abstract: A TPU composition comprising two or more TPU polymers is disclosed. The TPU composition gives a broad process window for melt coating applications. The blend of TPUs give better processing than either of the individual TPU polymers used in the blend alone. This results in melt coating which gives less matt and glossy streaks and allows faster coating speeds along with lower coating weight. The two or more TPU polymers used in the blend have a different soft segment. The different soft segment is created by using different molecular weight polyol for the TPU polymers or by using chemically different polyols.

Abstract: A liner for repairing damaged pipes, such as underground sewer or gas pipes is disclosed. The liner comprises a TPU coating on fibrous mat of non-woven fabric. The TPU coating contains a barrier layer to retard the migration of styrene from the liner to the media used to force the liner against the damaged pipe and to activate the thermoset resin. The thermoset resin converts the liner from a flexible state to a rigid state as the liner is cured in place inside the pipe.

Abstract: Thermoplastic polyurethanes exhibiting slowed annealing, reduced crystallinity, reduced viscosity sensitivity to shear, and improved hydrolytic stability are provided by utilizing small amounts of a polyether co-polyol with a polyester polyol and a symmetrical linear chain extender with small amounts of a different size chain extender.
