摘要:
According to this procedure, these steps are made:a) immersing a shaped mold (4) in a dipping process in a liquid synthetic polyisoprene (IR) (synthetic latex), wherein the shaped mold (4) has previously been treated with coagulation agent (coagulants) or thermally treated,b) after the immersion, the synthetic polyisoprene layer is left on the shaped mold (4) and is freed from all salts with water,c) thereafter, the synthetic polyisoprene layer together with the shaped mold (4) is vulcanized in an oven,d) the synthetic polyisoprene layer is removed from the mold (4),e) the salts precipitated by the vulcanization on the synthetic polyisoprene molded body (11) are washed off with water and a chlorine-containing solution,f) the synthetic polyisoprene molded body (11) is halogenated to neutralize its pH and to increase its suppleness in contact with body skin with a halogenating solution,g) the synthetic polyisoprene molded body (11) is dried. The electro-protective gloves thus produced are much more comfortable to wear, provide better insulation, even with thinner wall thickness, and they are more durable.
