WATERPROOFING AND AIRTIGHT PRESSURE-SENSITIVE ADHESIVE TAPE

摘要

The waterproofing and airtight pressure-sensitive adhesive tape is a pressure-sensitive adhesive tape containing a substrate having a pressure-sensitive adhesive layer on one side thereof, wherein the substrate is a rubber-made sheet; a film layer having non-self- adhesive properties and adhesive properties to the pressure-sensitive adhesive layer is formed on the substrate in the side opposite to the pressure-sensitive adhesive layer; and the waterproofing and airtight pressure-sensitive adhesive tape has an elongation at break (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/cm2 in both the longitudinal direction and the cross direction.
