How much heat can my Polyoxymethylene (POM) handle well handle??

I own a slotted tuner with a POM handle and am unsure if it will hold up to occasionally being rested on the side of a hot frypan for maybe a minute at a time? Or will it begin to melt within a few seconds? At the moment I remove the tuner each time I’ve finished using it, but I’m wondering if I’m giving it too much special treatment?

    Polyoxymethylene (POM) aka Acetal, has a very sharp melting point, and is a highly crystalline polymer, in other words, hit that 350°F mark or there abouts, and you have plastic in your soup. The question is are you resting the plastic directly on the frying pan, or just the metal part of the turner? If it's the plastic, that's not a good idea, only 30 seconds on a very hot pan could melt a nice little indention into the handle. I don't think it would be unusual for a frying pan to be over the 350°F melting point, although at the rim, it may not be that hot. The 80°C to 120°C is actually the continuous use temperature, and that's probably not an issue with a utensile handle.

      Thanks for clarifying that.

      The melting point of Polyoxymethylene is 165C to 175C, so it is 330F to 345F. Still, the plastic will start to deform before it actually melts. The upper working temperature is listed to be 80C - 120C and that is merely 176F to 248F
