摘要:
Valve and method for using it to insert a gas and punch orifices in plastic in moulds used for making hollow footwear soles. The valve is linearly actuated, includes a helical spring and a stop such that the valve body head seals against a seat in the valve casing. Its configuration is thus simple, inexpensive and reliable, while the method is efficient as it is performed during the processing cycle of the plastic.

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.

The silica preferably includes silica having an average particle size of more than 50 nm and 120 nm or less and silica having an average particle size of 5 nm to 50 nm, and the amount of the silica having an average particle size of more than 50 nm and 120 nm or less is 10 parts by mass to 50 parts by mass based on 100 parts by mass of the rubber ingredient and the amount of the silica having an average particle size of 5 nm to 50 nm is 10 parts by mass to 50 parts by mass based on 100 parts by mass of the rubber ingredient.
摘要:
Ein Barfußschuh mit Boden (1) und Schaft (2) sowie mit Arretierungen (3) zum Arretieren des Barfußschuhs am Fuß einer den Barfußschuh tragenden Person weist einen vollständig oder wenigstens teilweise ausschließlich aus Ringstrukturen (15) bestehenden Boden (1) auf. Vorzugsweise besteht auch der Schaft (2) vollständig aus Ringstrukturen (15) oder der Schaft weist wenigstens teilweise ausschließlich aus Ringstrukturen bestehende Bereiche auf. Dadurch wird ein Barfußschuh geschaffen, der die Füße einer den Barfußschuh tragenden Person in schnellem Wechsel nass, trocken kalt, warm, usw. hält, ohne dass die Gefahr einer Verletzung besteht und ohne dass die Gefahr eines Eindringens störender Fremdkörper besteht. Der Barfußschuh weist außerdem gute Haftreibungseigenschaften auf, auch auf variablem Untergrund. Der Barfußschuh ist schnell zu reinigen und weist ausreichende hygienische Eigenschaften auf. Der Barfußschuh ist außerdem leicht und flexibel und kann optisch ansprechend gestaltet werden.
