  • Patent number: 10793755
    Abstract: An object to be achieved by the present invention is to provide an industrially useful adhesive sheet that can be used to bond various adherends and has excellent peel adhesion, excellent push strength, and excellent holding power under static load. The object of the present invention can be achieved by an adhesive sheet having, on one side or both side of a substrate, an adhesive layer (A) having a tensile strength of 6 N/cm2 or more as determined from a stress-strain curve (a so-called S-S curve) at a strain of 100%.
    Type: Grant
    Filed: March 12, 2015

  • Publication number: 20110111660
    Abstract: Disclosed is a double-sided adhesive tape including a nonwoven fabric substrate and an adhesive layer composed of an acrylic adhesive composition. The nonwoven fabric substrate is obtained by fixing an acrylic copolymer having a glass transition temperature of ?10° C. or lower to a nonwoven fabric having a tensile strength of 5 to 45N/20 mm in both the MD direction and the TD direction. The adhesive layer has a storage modulus at a frequency of 1 Hz at 30° C. of 6×104 to 1×105 Pa. This double-sided adhesive tape has strong adhesive force and excellent removability.
