Title:
THERMALLY EXPANDABLE ADHESIVE TAPE, AND ARTICLE
Document Type and Number:
WIPO Patent Application WO/2017/208838
Kind Code:
A1
Abstract:
[Problem] To provide a thermally expandable adhesive tape capable of preventing loosening of bonding between adherends, generation of abnormal noise due to vibrations thereof, and separation of the adherends from each other even if the adherends repeatedly expand or contract at different ratios when left for a long period of time in an environment with a large variation in temperatures. [Solution] The present invention pertains to a thermally expandable adhesive tape used when fixing an adherend (d1) and an adherend (d2) in a fitted state, characterized in that the linear thermal expansion coefficient (d1-1) of the adherend (d1) and the linear thermal expansion coefficient (d2-1) of the adherend (d2) are in the range of [the linear thermal expansion coefficient (d2-1)/ the linear thermal expansion coefficient (d1-1)] = 2-1000.
