ISOSPEED is the technology leader in the field of innovative materials. We are the only company in the world that uses Polypropylene in the manufacture of strings, in addition to the more common materials. With Power Ribbons, we have developed a revolutionary string technology which uses elastic tapes instead of the traditional fibers. And, since 1990, we have carried out successful research on methods for the postprocessing and optimization of materials, such as double heating, a thermal aftertreatment which makes it possible for us to produce an unusual, triangular tennis string. Continuous advances in materials and technologies guarantee innovative, state-of-the-art products.
