Evaluation of Peeling Property of Polyisoprene-Based Pressure Sensitive Adhesive

In this paper, experimental method and statistical data analysis were demonstrated to evaluate peeling property of polyisoprene-based pressure sensitive adhesive. The peeling properties (peel strength/energy) of the polyisoprenebased pressure sensitive adhesive on the three different substrates (stainless steel, carbon steel, powder coating) were examined with varying peel velocity (25~1500 mm/min), peel test (90, 180), and the type of pressure sensitive adhesive (duct tape, clear tape). While little influence of relative humidity on the peel strength was found, the effect of roughness of the substrate was significant, revealing that the peel strength is inversely proportional to the roughness of the substrate. The highest peel strength was measured on the substrate of stainless steel, and the peel strength increased with increasing peel velocity and peel angle. The prediction of the peel strength as a function of peel angle and velocity was provided through a statistical data modeling with a 95% confidence interval.
