FIELD: chemistry.
SUBSTANCE: invention relates to a method for vulcanisation of polymer compositions and can be used for making brewing chambers, diaphragms and sealing sealed joints in vulcanising equipment for tires and rubber articles: autoclaves, vulcanizer formers, vertical stack presses operated for a long time in a moist steam-air medium with high temperature and high pressure. Method includes vulcanisation of article at the beginning at steam temperature of 165–170 °C for 50–45 minutes, and then at temperature of 195–205 °C for 10–5 minutes.
EFFECT: technical result is higher strength, hardness, tear resistance of article.
