Fundamentals and Mechanical
Properties of PSA Tapes 4. Morphological Analysis at Peeling PSA Tapes - Part 1 Yoshiaki Urahama Project Researcher, Yamagata University, Venture Business Laboratory, Yamagata,Japan Nippon Gomu Kyokaishi,(2004),77(1), 25-30 General Review in Japanese. Abstract Stringiness phenomena of PSA tapes at peeling were observed. (1) Effects of the backing materials; It becomes clear that the stringiness conformation of adhesives of the porous backings was observed as a honeycomb structure and that of the nonporous backing was a sawtooth shape structure. (2) Effects of the peel load; Stringiness phenomena of acrylic adhesive were observed under constant load conditions. In the results, peeling behavior was classified into the following two regions depending on peel load.
