We have completed evaluation of the urethane polymers CS-100FR and a leading competitor's mat sample for absorption and durability in the presence of common diesel fuel. The study consisted of a 12 week immersion carried out at 120F to artificially accelerate the testing.
At the start and at weekly intervals of the testing period sample weights were recorded and the differences compared to determine the affects of solubility in a hydrocarbon environment. The study revealed that the CS-100FR faired the best absorbing only 5.69% in weight and achieving maximum absorption while the leading competitor's sample absorbed 20.28% continuing on an upward trend in the same time period. The overall total percent absorption of diesel fuel could be used as direct indication of the breakdown of cured polymer and long term performance.
A copy of the study and actual test specimens has been included for your review.
