摘要

650.00261 COMPOSITION FOR VIBRATION DAMPING MATERIAL, VIBRATION DAMPING MOLDINGS AND METHOD A composition suitable for use in making vibration damping material includes an alicyclic resin, an isocyanate reactive component and an isocyanate. The vibration damping material can be molded into a desired, complex shape or can be used in a vibration damping member that includes a layer of the vibration damping material and at least one steel sheet. The vibration damping material can include a filler by applying the filler to a cavity surface prior to introducing the composition into the cavity. The isocyanate index can be shifted from 100 to achieve improved hot fusing ability.
