Product Description
P-70 has an even higher durometer than P-50. At room temperature the Shore A hardness is 60. The hardness can be raised to 70 by placing the cured rubber in a 200°F oven for 30 to 60 minutes. It has outstanding chemical and heat resistance and the rigidity to withstand the expansion of most polyurethane foams.
