Method for producing electrical insulation products made of synthetic polyisoprene (IR) and similar products

A process for the production of electrical insulation products for the personal protection equipment (Personal Protection Equipment PPE) in the high-voltage domain, that is for use in the area of electrical voltages of 500 V up to 36′000 V, in which polyisoprene is formed as a formed body in that synthetic polyisoprene (IR) or synthetic latex is used either by coagulation as layer on a mold (4) and then vulcanized, or injected with pressure into a hollow injection mold and vulcanized therein, and that the obtained demolded molded body (11) is made salt-free, pH-neutral and smooth in relation to body skin by washing, leaching and halogenation, in that

• a) either a shaped mold (4) in a dipping process previously treated with a coagulant solution is immersed into an emulsion of the synthetic polyisoprene (IR) when the shaped mold wetted with the coagulant solution is in a wet state, so that by coagulation on an outer surface of the shaped mold (4), a synthetic polyisoprene layer is formed, and then formed synthetic polyisoprene layer is vulcanized in an oven together with the shaped mold (4),
• or by means of an injection molding process a fluid synthetic polyisoprene is injected with pressure into the hollow injection mold in which vulcanization takes place and a synthetic polyisoprene layer is formed and vulcanized within the hollow injection mold,
• b) vulcanized synthetic polyisoprene layer as a synthetic polyisoprene molded body (11) is removed from the shaped mold (4) or is demolded by separating parts of the injection mold;
• c) salts precipitated by vulcanization on the synthetic polyisoprene-molded body (11) are washed away with a water solution;
• d) the synthetic polyisoprene molded body (11) is surface-treated by halogenating the synthetic polyisoprene molded body with a halogenating solution for neutralizing pH and increasing suppleness of the synthetic polyisoprene molded body with respect to body skin;
• and
• e) the synthetic polyisoprene molded body (11) is dried.
