Burgenländischer Innovationspreis 2022 - ISOSPORT awarded

ISOSPORT has been awarded at the "Burgenländischer Innovationspreis 2022" in the category "Small, medium and large companies". The ISOSPEED tennis string "SECOND SERVICE" was nominated, which is made of 100% recycled PET bottles and thus sets new standards in sustainability.

Tennis string made from recycled PET bottles

SECOND SERVICE joins the list of innovative tennis strings that ISOSPORT has been producing in Eisenstadt under the "ISOSPEED Tennissaiten" brand for over 30 years and successfully marketing worldwide.

Tennis strings need various properties to provide the best possible support for players in their sport: they must dampen vibrations, pass on top spin, and be elastic and durable. In order to be able to meet the demand for a sustainable solution, ISOSPORT has developed a string made from recycled PET bottles - a global innovation, because no company has taken up this challenge before. This also presented ISOSPORT with a number of tasks, after all, recycled material cannot be processed directly into tennis strings like "new material". Rather, it requires the right additives to achieve the properties mentioned above.

This new string is a round polyester monofilament with a diameter of about 1.25 millimeters. The product is manufactured using an extrusion process, then stretched and heat-treated. In this way, irregularities are eliminated in several steps and the loss of voltage is minimized. Finally, it is finished with a layer of wax, which not only makes stringing easier, but also increases the lifespan of the string.

With this new production process, the market innovation has succeeded: The world's first tennis string made from recycled PET bottles meets the demand of tennis customers who, like ISOSPORT itself, value sustainability, quality and innovation.
