Abstract: |
The invention relates to a method for producing a sound and/or thermal insulation element using foamable and/or prefoamed polymer particles which are coated with a binding agent, and preferably with an organic binding agent, and thereafter are subjected to a shaping process during which the polymer particles are bonded and/or sintered to one another, the bonding being caused by way of the binding agent. According to the invention, a non-hydrophilic binding agent is used for coating the foamable and/or prefoamed polymer particles. The invention furthermore relates to a sound and/or thermal insulation element. |
