  • Pyrimidine derivatives as hardness stabilizers
    Patent number: 6646029
    Abstract: A vulcanizable composition comprising a sulfur vulcanizable rubber, a sulfur vulcanizing agent, an accelerating agent selected from the group consisting of non-thiazole sulfenamide accelerators in an amount effective to not substantially inhibit vulcanization and an amount effective to improve the hardness stabilization of said rubber upon vulcanization of a hardness stabilization agent comprising a pyrimidine derivative. A method of improving the hardness stabilization of a composition comprising a sulfur vulcanizable rubber by adding to said composition the accelerators and pyrimidine derivative.
    Type: Grant
    Filed: March 21, 2001
    Date of Patent: November 11, 2003
    Assignee: Flexsys America L.P.
    Inventors: Horng-Jau Lin, Rabindra Nath Datta, Otto William Maender
  • Pyrimidine derivatives as hardness stabilizers
    Patent number: 6465604
    Abstract: The invention comprises a vulcanizable composition comprising a sulfur vulcanizable rubber, a sulfur vulcanizing agent, an accelerating agent in an amount effective to accelerate vulcanization and sufficient to not substantially inhibit vulcanization, and an amount effective to improve the hardness stabilization of said rubber upon vulcanization of a pyrimidine derivative. The invention also comprises a method of improving the hardness stabilization of a composition comprising a sulfur vulcanizable rubber by adding the above accelerating agent and pyrimidine derivative to the composition.

  • Rubber compositions containing 2-pyrazine sulfenamides
    Patent number: 5374689
    Abstract: Thiols, or thiolate salts, disulfides and sulfenamides of certain pyrazines are effective accelerators in the sulfur vulcanization of rubber. These compounds, based on 2-pyrazine, show improved rates of vulcanization compared with known sulfenamide accelerators.
