Document Type and Number:
WIPO Patent Application WO/2017/146108
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide: a two-sided adhesive tape that has excellent heat resistance and repulsion resistance and is unlikely to peel off, in particular, even when a cover of a vehicle-mounted panel or vehicle-mounted head-up display has been fixed; and a two-sided adhesive tape for vehicle-mounted component fixation and a two-sided adhesive tape for vehicle-mounted head-up display cover fixation, the tapes being composed of said two-sided adhesive tape. The present invention is a two-sided adhesive tape having an acrylic adhesive layer on two sides of a substrate, wherein the substrate is composed of a foam, the thickness of the substrate is 1500 μm or less, and the foam has: a crystalline melting temperature peak, measured by a differential scanning calorimeter, of 140°C or higher; a foaming expansion ratio of 15 cm3/g or less; and a bubble aspect ratio (MD mean bubble diameter/TD mean bubble diameter) of 0.9 to 3.
