Title:
DAMPING SHEET
Document Type and Number:
Japanese Patent JPH06328607
Kind Code:
A
Abstract:
PURPOSE: To provide a damping sheet enhanced in damping capacity by setting the modulus of elasticity of the adhesive layer bonded to an adherend at the normal temp. to a specific value and allowing the adhesive layer to enter a rough surface to develop anchoring effect to enhance the adhesiveness thereof.
CONSTITUTION: In a damping sheet 1 having a three-layered structure consisting of a highly elastic restriction layer 2, a viscoelastic elasticity of the adhesive layer 4 at the normal temp. is set to 106-1010dyne/cm2.
