Method for producing a rubber-plastic composite

A method for producing a rubber-plastic composite, comprising the following steps:

• a) shaping an elastomer which is unvulcanized to form a shaped elastomer,
• b) partially vulcanizing the shaped elastomer at a temperature of at least 140° C. up to a degree of vulcanization in the range from 10% to 40% to form a partially vulcanized elastomer,
• c) cooling the partially vulcanized elastomer to a temperature of less than 100° C. within less than 20 minutes,
• d) overmolding the partially vulcanized elastomer with a plastic, and
• e) heat treating the partially vulcanized elastomer overmolded with the plastic at a temperature in the range from 100° C. to 170° C. for a duration of from 5 minutes to 5 hours to complete the vulcanization and thus forming the rubber-plastic composite;
• wherein the plastic is polyamide (PA) and the elastomer is (partially) hydrogenated nitrile rubber (HNBR).
