Abstract
Official abstract text for this publication.
A method for producing bead foams from foam beads based on thermoplastic elastomers, especially thermoplastic polyurethane, comprises foam beads being wetted with a polar liquid and joined together thermally in a mold via high-frequency electromagnetic radiation, especially microwave radiation, and also the bead foams obtainable therefrom.
First claim
Opening claim text (preview).
1 . A method for producing bead foams from foam beads based on thermoplastic elastomers, the method comprising wetting foam beads with a polar liquid and joining the foam beads together thermally in a mold via high-frequency electromagnetic radiation. 2 . The method according to claim 1 , wherein the foam beads are joined together thermally via microwaves in the frequency range between 100 MHz and 300 GHz. 3 . The method according to claim 1 , wherein the foam beads comprise a thermoplastic polyurethane. 4 . The method according to claim 1 , wherein the foam beads have a bulk density in the range from 30 to 250 kg/m 3 . 5 . The method according to claim 1 , wherein the foam beads are wetted with the polar liquid in proportions of 0.1 to 10 wt %, based on the foam beads. 6 . The method according to claim 1 , wherein the polar liquid has a boiling point in the range from 120° C. to 350° C. 7 . The method according to claim 1 , wherein the polar liquid comprises (a) esters of carboxylic acids and diols or triols or (b) glycols or liquid polyglycols or mixtures of (a) and (b). 8 . The method according to claim 1 , wherein the polar liquid comprises glycol esters of acetic or citric acid, glycerol esters of acetic or citric acid, triethylene glycol, tripropylene glycol or mixtures thereof. 9 . A bead foam obtained by the method of claim 1 . 10 . A packaging or footwear, comprising the bead foam of claim 9 .
