The present invention is directed to a process for the preparation of a tube with an outer diameter in the range of from 10 &#x3bc;m to 250 &#x3bc;m consisting of a composition comprising a thermoplastic polyurethane as well as to a tube with an outer diameter in the range of from 10 &#x3bc;m to 250 &#x3bc;m consisting of a composition comprising a thermoplastic polyurethane obtained or obtainable by the process according to the invention. The invention is further directed to the use of a tube according to the invention as a tube for the transportation of a fluid or as gas membrane tube or as an elastic fiber.

Very thin tube made from TPU and its production process

A process for producing foamed thermoplastic polyurethane particles comprises the steps of a) melting a thermoplastic polyurethane in a first extruder (E), b) injecting a gaseous blowing agent in a second extruder (E), c) impregnating the gaseous blowing agent homogeneously into the thermoplastic polyurethane melt in a third extruder (E), d) extruding the impregnated thermoplastic polyurethane melt through a die plate and granulating the melt in an underwater granulation device under temperature and pressure conditions to form foamed thermoplastic polyurethane particles.

Process for producing foams based on thermoplastic polyurethanes

This invention is directed to a thermoplastic polyurethanes composition comprising polyether-based thermoplastic polyurethane and 1,2-cyclohexane dicarboxylic acid ester and preparation processes thereof. The thermoplastic polyurethane composition has a good mold release behavior in injection molding without undesirably significant shrinkage and surface blooming of final product.
