PP polyester is an amorphous, its melting point should be above 220, its heat distortion temperature should be about 121 degrees, but because it is a macromolecular polymer after all, the higher the temperature, the possibility of precipitation of small analytical oligomers The larger, and most of these substances are not conducive to human health, and according to customer use, the general boiling water is 100 degrees, so the general plastic cups will not be marked more than 100 degrees.
