PETG melting point

"PETG heat distortion temperature is 69~70 degrees, PCTG heat distortion temperature is 75 degrees, Eastman's TRITAN material is resistant to 99 degrees and 109 degrees. These temperatures can be reached under certain conditions, such as atmospheric pressure and product thickness. Relationship: With the increase of CHDM in the copolymer, the melting point decreases, the glass transition temperature increases, and the crystallinity decreases, and finally an amorphous polymer is formed.
