  • RUBBER MIXTURE COMPRISING A RAPID VULCANIZATION ACCELERATOR
    Publication number: 20250019527
    Abstract: A rubber compound has at least two glass transition temperatures Tg1 and Tg2, based on at least one vulcanization system and at least two rubber compositions C1 and C2, the composition C1 comprising at least one elastomer E1 and having a Tg1, the composition C2 comprising at least one elastomer E2 different from E1, and a reinforcing filler, and the composition C2 having a Tg2, in which: Tg1??50° C.; the rubber compound satisfies Tg1-Tg2?23° C.; the rubber compound has a loss factor profile which is such that all the tan ? peaks present at a temperature above the temperature Tg1 have a width at half height of ?23° C.; E1 is predominant in the rubber compound; E2 is an isoprene diene elastomer; and the vulcanization system comprises at least one vulcanization accelerator A selected from thiurams, dithiocarbamates, dithiophosphates, xanthates and mixtures thereof.

  • Method for the production of fibres with a high content of colloidal particles and composite fibres obtained thus
    Patent number: 7867421
    Abstract: The invention relates to a method for the production of composite fibers with an increased content of colloidal particles, made from a pre-fiber, comprising a polymeric binder and colloidal particles, during which the chemical structure of the polymeric binder is degraded at a temperature of the order of ambient temperature such as to at least partially eliminate the above. The invention further relates to a fiber comprising a polymeric binder and colloidal particles, combining an excellent mechanical strength and a content of colloidal particles greater than 70% by mass.
