Abstract
The present invention relates to methods for the welding of foam particles, by electromagnetic waves, wherein foam particles with a surface modification are welded in a molding tool by electromagnetic waves, wherein the surface modification is produced by contacting the foam particles with a solution containing polymers which are capable of forming intra- or inter-molecular covalent bonds, under the conditions required for this purpose.
Claims16
Methods for welding of foam particles using electromagnetic waves, in which foam particles with a surface modification are welded in a molding tool by electromagnetic waves, wherein the surface modification is made by providing that the foam particles are contacted by a solution containing polymers that are capable of forming intra-or inter-molecular covalent bonds, and the polymers that are capable of forming intra-or inter-molecular covalent bonds are selected from polyvinyl alcohol or polyvinylpyrrolidone and have carboxyl functional groups.
