Waterproof and airtight pressure-sensitive adhesive tape

摘要

A waterproof and airtight pressure-sensitive adhesive tape includes a substrate and a pressure-sensitive adhesive layer on one surface thereof, wherein the substrate is a rubber-made sheet; and a film-like material having elongation properties is laminated on a surface in the opposite side to the pressure-sensitive adhesive layer of the substrate. It is preferable that the rubber-made sheet as the substrate has an elongation at the time of breakage (distance between two gage marks: 40 mm, drawing rate: 300 mm/min) of from 200 to 1,200 % in both the longitudinal direction and the cross direction and a stress under 100 % elongation (distance between two gage marks: 40 mm, drawing rate: 50 mm/min) of from 10 to 100 N/cm 2 in both the longitudinal direction and the cross direction.
