What is the deforming temperature PET?

The deforming temperature of polyethylene terephthalate (PET) typically ranges from about 60°C to 80°C (140°F to 176°F). At this temperature, PET can begin to soften and lose its structural integrity, making it susceptible to deformation under stress. The exact temperature can vary based on the specific grade of PET and its processing history. Careful consideration of this temperature is crucial in applications involving heat exposure.
