Method For Producing A Sound- And/or Heat-insulating Element, And Sound- And/or Heat-insulating Element
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.

- 22. A method for producing a sound and/or thermal insulation element, comprising:
providing foamable and/or prefoamed polymer particles which are coated with a non-hydrophilic binding agent; and thereafter subjecting the foamable and/or prefoamed polymer particles to a shaping process during which the foamable and/or prefoamed polymer particles are bonded and/or sintered to one another.
- 35. A sound and/or thermal insulation element, comprising:
a polymer particle foam, comprising polymer particles that are bonded and/or sintered to one another, the bonding being caused by way of a non-hydrophilic binding agent that forms a coating that envelopes the polymer particles at least partially.
