This investigation was made to determine the effect of reaction blocks on the forming pressures produced in solid pad rubber forming. The pressures developed after the addition of six basic reaction block designs, at four distances from the form block, were determined and compared to the pressures developed without a reaction block.

The effect of rubber hardness was determined by conducting duplicate tests with pads having a durometer hardness of 50 and 65 Shore "A".

The addition of a reaction block produced a maximum increase in pressure of 9.75% and was found to be detrimental under many of the test conditions.
