Estimating the term…
The present invention relates to a method for the preparation of a particle foam molded part comprising fusing coated foam particles by supplying energy at least partially through an electromagnetic field with a frequency in the range from 1 MHz to 100 MHz, wherein the coated foam particles comprise a polymeric coating selected from the group consisting of acrylic polymers, styrene-acrylic polymers, vinylester polymers, ethylene vinylester polymers, styrene butadiene polymers, polyester polymers, polyamide polymers, polyolefin polymers, polyurethane polymers, polyurethane-polyacrylate hybrid polymers and polyurethane-polystyrene-butadiene hybrid polymers. The invention is further directed to the molded part obtained in the process as well as the use thereof in shoe soles, part of shoe soles, shoe intermediate soles shoe insoles, damping elements, cushioning elements, underlays, grips, flooring, mattresses, sporting goods, bicycle saddles, tires and in automotive interiors and exteriors.
A method for the preparation of a particle foam molded part, comprising fusing coated foam particles by supplying energy at least partially through an electromagnetic field with a frequency in the range from 1 MHz to 100 MHz, wherein the coated foam particles comprise a polymeric coating, and wherein the polymeric coating comprises a polyurethane with a K-value in the range from 5 to 100 determined according to DIN EN ISO 1628-1 2021.
