  • PULVERULENT MIXTURE OF PRECROSSLINKED NITRILE RUBBERS
    Publication number: 20220073668
    Abstract: What are provided are pulverulent mixtures based on specific nitrile rubbers and at least one separating agent, and also a process for producing vulcanizable mixtures and vulcanizates made from these pulverulent mixtures, and the resultant vulcanizates and their use, especially in tyre treads, where an improvement in wet skid resistance, dry grip and rolling resistance delivers is observed with simultaneously good mixing characteristics.

  • Stabilized rubbers
    Patent number: 10414901
    Abstract: Novel rubbers are provided which are stabilized by a specific combination of at least three different anti ageing compounds. Said rubbers dispose of an increase storage stability as well as an improved colour stability over the short term as well as over the long term. The invention also relates a process for producing said novel rubbers, vulcanizable mixtures based thereon, a process for producing vulcanizates from those mixtures and the vulcanizates obtained.
