Typically the operating temperature for Polyurethanes ranges from -80 degrees to 200 degrees Fahrenheit. These are general industry standards and should be adjusted based on your application. Temps at the high end can cause the material to weaken, revert to a sticky form, and/or may burn. On the other end below 0 degrees can harden the material and temps below -80 degrees can make it shatterable. We supply polyurethanes in Poly Load Protectors, Poly Clad Forks, Poly Clad Extensions, Fork Kushions, and Impact Protectors
