PURPOSE: To provide an adhesive tape or sheet which has high mechanical strength and flexibility and can be attached to a substrate with an uneven or curved surface for a long period, prepared by forming an acrylic polymer-based adhesive layer on a soft plastic foam sheet consisting of a linear low-density polyethylene and an ethylene/vinyl acetate or ethylene/ethyl acrylate copolymer. n CONSTITUTION: An acrylic polymer-based adhesive layer is formed on one or both sides of a soft plastic foam consisting of (A) linear low-density polyethylene and (B) ethylene/vinyl acetate copolymer or ethylene/ethyl acrylate copolymer. For improved mechanical strength, flexibility, adhesion and formability of the foam, the blend ratio of (A) to (B) should be 1:4W4:1 and the ethylene/ethyl acrylate copolymer should have an ethyl acrylate content of 7W25%. n COPYRIGHT: (C)1984,JPO&Japio |
