Patent number: 10165823Abstract: A process for producing a shoe sole, having a hybrid material of a polyurethane foam as a matrix material and an inlay component of expanded particles of a thermoplastic polyurethane is provided. The process includes preparing an inlay form by joining the expanded particles of a thermoplastic polyurethane in an amount and size of the desired inlay; preparing the shoe sole by placing the prepared inlay form in a shoe sole mold such that an edge of the inlay component is 0.2 cm or more from an edge of the shoe sole mold; embedding the inlay form within a reaction mixture in the shoe sole mold; and reacting the reaction mixture to form the matrix in the shoe sole mold.Type: GrantFiled: December 7, 2017Date of Patent: January 1, 2019Assignee: BASF SEInventors: Frank Prissok, Andre Kamm, Bin-Eric Chen, Yoke Khim Raymond Toh

Patent number: 9894957Abstract: The present invention relates to a process for producing a shoe sole comprising a hybrid material made of a polyurethane foam as matrix material and of foamed particles of thermoplastic polyurethane by preparing an inlay of joined expanded particles (c?) of thermoplastic polyurethane and placing the joined expanded particles of thermoplastic polyurethane in a mould and embedding the inlay with a reaction mixture obtainable by mixing (a) polyisocyanates with (b) compounds having hydrogen atoms reactive toward isocyanates, and if appropriate, with (d) chain extenders and/or crosslinking agents, and with (e) catalysts, and with (f) blowing agents, and with (g) further additives and reacting the reaction mixture to give the shoe sole. The present invention further relates to shoe soles, obtainable by such a process.Type: GrantFiled: November 14, 2011Date of Patent: February 20, 2018Assignee: BASF SEInventors: Frank Prissok, Andre Kamm, Bin-Eric Chen, Yoke Khim Raymond Toh

Publication number: 20160122465Abstract: The present invention discloses a thermoplastic polyurethane comprising substantially no plasticizers and having a Shore A hardness of 60 or less, which is prepared by a one-step polymerization of i) linear polyol, ii) organic diisocyanate and iii) glycol chain extender mainly comprising ethylene glycol and/or 1,3-propanediol; wherein the linear polyol (i) has a number average molecular weight within the range of from 1.5×103 g/mol to 5.0×103 g/mol. The thermoplastic polyurethane of the present invention can be easily produced by conventional production methods, and the thermoplastic polyurethane thus produced can be molded to articles in practicable processing cycles. Moreover, the thermoplastic polyurethane articles have low shrinkage, have good low-temperature properties and good mechanical properties, and do not harden substantially at low temperature.Type: ApplicationFiled: May 28, 2014Publication date: May 5, 2016Applicant: BASF SEInventors: DeHui YIN, Bin-Eric CHEN, Akira NOMURA, Tienkuan LIM
