  • Patent number: 5784283
    Abstract: A database of reversion cure constants is provided by measuring a physical property of a rubber formulation at two different temperatures as a function of time, calculating a set of cure constants for the rubber formulation which account for reversion, and storing the constants for later use either to optimize cure for a given process or of a given compound, or to assure quality of a raw compound. The invention also provides a curing press for optimizing cure including a mold, a heater, a temperature transducer, a computer and the database.
    Type: Grant
    Filed: August 1, 1997
    Date of Patent: July 21, 1998
    Assignee: Pirelli Coordinamento Pneumatici S.p.A.
