THE EFFECT OF BASE OIL COMPOSITION ON PRESSURE SENSITIVE ADHESIVE PROPERTIES

摘要

Hot-melt pressure-sensitive adhesives (PSAs) are typically composed of an elastomeric styrenic block copolymer, tackifying resin and oil. Given that the oil, which acts as a plasticizer, is a major component of the adhesive formulation, it is important to understand how the properties of the oil can affect adhesive performance. In this study, we demonstrate how the chemical composition and viscosity of oils impact adhesive properties. Thirteen different base oils, selected from iso-paraffinic, paraffinic, naphthenic and aromatic types, were tested. We attempted to bring a new perspective to this technology by bringing together researchers from the fields of petroleum and adhesion.
