FIELD: machine building.
SUBSTANCE: invention relates to vibration damping material for use in bound damping system and to damping article with connected layer used in cars for damping noise. Damping material with connected layer consists of bitumen material, binder and colophonic amplifier adhesive ability, bitumen material represents bitumen with permeability of 160/220 and measured by ring and ball method softening temperature between 35 and 43 °C.
EFFECT: damping material shows better behaviour than currently used materials, as well as is self-adhesive.
