Body Structure
Historical Evolution of Polyimide TapesPolyimide tapes, also known as Kapton tapes, have undergone significant technological advancements over the past century. The journey began in 1908 when the first polyimide synthesis was reported, but its potential was largely overlooked until the 1950s. DuPont’s pivotal research in the 1960s transformed the material into a commercial reality with the launch of Kapton H, F, and V series films. These tapes, renowned for their exceptional thermal stability and electrical insulation, became industry standards in aerospace, electronics, and electrical engineering.
By the 1980s, collaborations between global giants like DuPont and Toray expanded production capacity, introducing improved versions such as HN, FN, and VN films. Concurrently, Japanese companies like Ube Industries developed Upilex series PI films, offering superior heat resistance and dimensional stability. The evolution continued with the integration of environmental regulations, driving the development of RoHS-compliant variants. Today, polyimide tapes are at the forefront of high-performance applications, underpinned by continuous R&D in material science and coating technologies.
