Rubber blocks - Import export

The sliding surfaces used in the past had a number of weak points, which can be attributed to the granules used: Quartz sand is too hard and destroys the base coverings very quickly, while the various rubber granules are too soft and too uneven in shape, so that they in turn are ground up relatively quickly. Both sliding media are controversial due to the dust they generate and bring with them unpleasant side effects such as breathing difficulties, discolouration of clothing and a great deal of cleaning work in the tennis hall and social areas. A new manufacturing process has made significant progress possible: Perfect-Glide tennis granules are not ground from a block of rubber like conventional granules, but are spun into threads using an extruder and then cut to a defined length in a cooling bath. This process enables the production of fine, dust-free extruder micro-granules in a new, optimised lens shape.
