Dear Mr. Hofmeister,

    This is Michael Knight at CASTALDO. 

    The life expectancy of our VLT rubber after it has been vulcanized?
    Just about forever. Or certainly a very, very, very long time.
    Centuries? I'll let you know more about this in a few hundred years. 

    If you mean the service life of molds made with this material, then
    the answer is: Thousands of injections, but of course it all depends
    on how complicated the design is, if you have cut the mold to make
    wax removal easy or stressful on the mold and how rough you are in
    pulling waxes. 

    A second mold made in some other compound would suffer from the same
    user variables and would have the same service life.

Michael Knight
