Abstract

L'invention porte sur un manchon chauffant (1) en tant que composant d'un équipement de vulcanisation destiné à fabriquer un article tubulaire, en particulier sous forme d'une courroie d'entraînement fermée sans fin, comportant un corps de base constitué d'un matériau vulcanisable, le manchon chauffant (1) étant constitué d'un matériau polymère résistant aux conditions de vulcanisation, le manchon chauffant (1) comportant, selon l'invention, au moins une couche intérieure (2) et une couche extérieure (3), la couche intérieure (2) étant en un matériau plus dur que la couche extérieure (3). La couche intérieure (2) du manchon chauffant (1) a, dans la phase de vulcanisation, de préférence une dureté Shore A plus grande que celle de l'article à vulcaniser, ce qui est le cas notamment avec les courroies d'entraînement. La couche intérieure (2) est, de préférence, constituée d'un mélange EPDM réticulé par vulcanisation au soufre ou aux peroxydes, ayant une dureté Shore A de 82 à 89 pour une épaisseur de couche de 5 à 7 mm. La couche extérieure (3) est constituée notamment d'un mélange de caoutchouc butyle réticulé aux résines, ayant une dureté Shore A de 64 à 75 pour une épaisseur de couche de 1,5 à 4 mm.
