IF NOT HARDNESS, WHAT IS IMPORTANT IN SPECIFYING?
Most applications require the consideration of compressive stress-strain relationships, abrasion or wear resistance, and resistance to environment (heat, weather, oil and chemicals).
First, lets take resistance to oils and chemicals. Some or all urethanes are resistant to the following. Here is a partial list of media to which our products have been subjected: This data was obtained on small billets totally immersed. Always test specific compounds under your particular field conditions.
Note:
Unless otherwise stated, all immersion test data was generated at room temperature. Elevated temperatures usually increase the fluid's effect on the urethane. If you have a specification not listed, call us. We have more test results on file.
