It is a good idea to look at some of the temperatures so that you can get an understanding of how this type of coating will fare against the traditional Teflon coating. It is also important to understand that this is not the only coating out there that can take high temperatures.
We are comparing this against Teflon as this is was the industry standard and this is the coating that has had so much bad publicity. We have written a little bit about the dangers of Teflon here .
It is also important to point out here that we have little understanding or evidence of the long-term effect of any of the newer cookware that we use. There may be some effects that will not know about until nonstick cookware has come of age.
The end result of all of this is that this cookware has a much larger range of temperatures that it can cook with and the coating does not break down in the same way as other traditional coatings.
We, of course, will always recommend that you should cook within the limits stipulated by the manufacturers. Cooking outside of these stipulations is for the most part where nonstick cookware goes wrong.
