Polyurethane Based Pressure Sensitive Adhesives(PSAs) Using e-Beam Irradiation forMedical Application

摘要

Pressure-sensitive adhesives (PSAs) present an interesting class of products that offer great potential to produce a novel generation of self-adhesives with excellent properties. The term pressure sensitive describes adhesives that are aggressively and permanently tacky in the dry form at room temperature and firmly adhere to a variety of dissimilar surfaces upon mere contact of finger or hand pressure. In this paper various classes and medical applications of e-beam cured polyurethane pressure sensitive adhesives, their cure characteristics and requirements have been reviewed and presented. The paper also reviews the evolution of biomedical adhesives, their merits and demerits and finally gap areas, challenges and opportunities in this area.
