Lawler wrote to Marsh, “We would not recommend using polyester foam in such an environment and have no direct data to use to calculate the rate of hydrolysis. Polyether foam lifetime would not be expected to reduce significantly at the stated conditions. Use with pure oxygen could shorten the lifetime some by promoting more rapid oxidation. I do not know the extent of the reduction, but do not expect it to be overly significant.”
