What is the EPDM? Rubber crumb (EPDM) is a high quality primary product, which uses natural or isoprene rubber. The filler is ethylene-propylene components (50...70% of molar mass), which create cyclic chains with rubber (20...40% of molar mass). In the process of polymerization, pigments are added, the output is a homogeneously dyed mass, as a result of which the resulting crumb has a uniform color throughout the structure. As a result, the top layer of the pads is more often laid out precisely from rubber crumb, since its color remains unchanged.
