Abstract (en)

[origin: DE10237366A1] A noise insulating material (1) especially for automobiles, prepared from rubber and PUR-plastic, where the rubber (12) and PUR plastic (13) are mixed together, rubber (12) forming a matrix in which a number of gas-filled elastic hollow bodies (14) are embedded is new. An Independent claim is included for a process for preparation of the noise insulating material (SIM). The thermoplastic rubber particles and PUR plastic particles are extruded to give a foam-like mixed material, where a propellant is added containing microhollow bodies (14), with a shell consisting of mixed polymer and the material is expanded under heat.
