Abstract (en)
[origin: EP2333155A2] Electrical insulation rail joint and rail (1) for a railway, provided with a coating of a synthetic rubber, wherein the coating can have one or more of the following mechanical properties: hardness Shore A of at least 85 or 90, such as between 92 and 95; a hardness Shore D of at least 30 or 35, e.g. between 38 and 42; a tension strength of at least 15 or 20, e.g. 21 N/mm2, an elongation at failure of at least 300 or 350 or 400, e.g. 425%; and a rupture strength of at least 45 or 50 or 55, e.g. 58 kN/m. The coating can be made of a copolymer, preferably a polyol and an isosyanate, preferably such that an elastomeric polyurethane or polyurethane rubber is obtained.
