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.
Pressure sensitive adhesive, Stringiness phenomena, Porous backing, Honeycomb structure, Sawtooth shape structure
