Title:
ADHESIVE TAPE
Document Type and Number:
WIPO Patent Application WO/2022/092199
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an adhesive tape having exceptional repeated shock resistance. The present invention is an adhesive tape having a multilayer substrate and an adhesive agent layer that is layered on at least one surface of the multilayer substrate, wherein: the multilayer substrate has a substrate layer and a resin layer that is layered on at least one surface of the substrate layer; the storage elastic modulus E' of the substrate layer in measurement of dynamic viscoelasticity at 10°C is 2.0-21 MPa (inclusive); the Young's modulus of the resin layer at 23°C is 500 MPa or greater; and the fracture elongation of the adhesive agent layer in measurement of shear adhesive power at 23°C is 30% or greater, and the storage elastic modulus G' of the adhesive agent layer in measurement of dynamic viscoelasticity at 10°C is 0.13-7.0 MPa (inclusive).
