Rubber curing alternatives



We're working with a friction materials company (brake pads for mining vehicles) regarding curing methods for the nitrile rubber on brake pads.  It is actually a mixture of rubber, cork and clay, but the rubber is the major component.  There are customer specifications that require material that is "less" compressible.  They have goals of 100 psi, .003 mills compression, 200 psi at .007 and 300 psi at .009.

They are testing MEK (soaking rubber sheets in tank) but are interested in alternatives.  Besides the additional air and hazardous waste oversight, health and safety issues come into play.

Any case studies or examples of alternative curing processes for this type of industry?


Thanks in advance.
