Self-supporting heat and sound insulation for e.g. automobile industry, comprises foam particles bonded by comparatively long fibers

摘要

Bonds (4) are formed at points within the insulant volume (5). Here fibers (3) are plasticized or melted-onto the foam particles (2). The length of a substantial proportion of the fibers is a multiple of the foam particle size. An Independent claim is also included for the corresponding method.
