PRESSURE-SENSITIVE ADHESIVE TAPE

摘要

PROBLEM TO BE SOLVED: To provide a pressure-sensitive adhesive film adhering firmly to an adherend at a temperature not higher than a prescribed temperature and hard to release, however when heated at the temperature higher than the prescribed temperature, being easily released from the adherend without leaving any residual material. SOLUTION: This pressure-sensitive adhesive tape comprises the pressure-sensitive adhesive film that comprises a film substrate and a pressure-sensitive adhesive layer applied on at least one side of the film substrate, wherein the film substrate has an elastic modulus of≥7.0×108Pa at the temperature not higher than the prescribed temperature and has elastic modulus of≤5.0×108Pa and elongation at break of≥150% at the temperature higher than the prescribed temperature.
