Pressure-Sensitive Adhesives

There are three main types of pressure-sensitive adhesives (PSAs): rubber, acrylic, and silicone. Overviewing the specific benefits of each type of adhesive, this paper uses a tabular format to explain how PSA softness or firmness affects adhesion, cohesion, viscosity, and elasticity. Highlighting how surface texture and contour can affect adhesive bonds, it states that adhesion is also affected by the environment in which it is used and the manner in which it is applied in both high and low temperatures. Explaining how PSA tapes use different types of carriers such as paper, plastic films, or acrylic foam cores to 'carry' the adhesive to its intended point of use, it concludes that Interstate Specialty Products can partner with PSA tape manufacturers to provide expert die cutting services such as steel rule, rotary, high tonnage beam press, high-speed punch, digital cutting, as well as slitting, laminating, and matched metal die stamping services along with cleanroom die cutting.
