    Compounds of URETHANE RUBBER can be molder by compression, injection and transfer molding procedures. Excellent mold definition is obtainable in press cures. The linear shrinkage of vulcanized of UR varies somewhat with the type of loading, but in general this value is approximately 1.5%, which is comparable to that of neoprene.

    Optimum press cures are obtained with peroxide curing system, temperatures from 305℉ to 340℉ with cycles ranging from 4 to 5 minutes.

    Excellent mold release is provided by lubricant or silicone mold release lubricants, but indiscriminate use can cause poor flow and knitting problems.
    Notice: These values are based on the test of our present laboratory test specimens.
