Re: Rubber curing alternatives



Dave,

There is a company in Illinois that makes brakes for trains.  Their brakes 
do not have the nitrate rubber.  Several years ago they reformulated the 
brakes to eliminate toluene as a solvent in their mixture.  The new 
formulation, without any solvent, produced a much longer lasting brake.  We 
awarded them an Illinois Govs. P2 Award for their accomplishments.  A few 
years later they we bought out but I could probably track them down if you 
think their technology might apply to your situation.
