Let’s look at that in two parts. First, our products are made of a fire-retardant material. In other words, the material will not hold a flame. It is self-extinguishing.
Second, As far as contact heat is concerned, we suggest using common sense. A hot cup of coffee should be just fine, whereas a frying pan right off of the flame is more likely to do damage. To be conservative, we suggest limiting heat exposure to no more than 150-175 degrees F.
