World’s thinnest tape claimed

Put into perspective the new products are just a tenth the thickness of a strand of human hair. The thinnest of the new tapes are just 5µm thick, consisting of a 2µm backing and, on each side, a 1.5µm coating of an acrylate adhesive. Worldwide consumer demand for slimmer television sets and hand-held devices has driven product development forward at a rapid pace. For example 2015 worldwide sales of smartphones are predicted to double existing levels, rising to some 980 million units a year. This in turn is driving the need for innovation among the providers of parts and services. For tesa the requirement has been to produce double sided tapes which not only save space but help to dissipate the heat generated by components such as processors, which react to temperatures as high as 100 degrees Celsius. Ultra-flat devices will now benefit from the dual action of the new tesa tapes which hold the sheets of graphite in place that regulate and dissipate heat while offering excellent thermal conductivity in themselves.
