WebDSC of PETE 4 The second direct information obtainable from DSC thermograms is the enthalpy associated with first order processes. Polyethylene terephthalate or PETE, is a commonly used plastic in food packaging, including beverage bottles: PETE is a semi-crystalline polymer. After molding, the plastic has crystalline and amorphous regions. WebAdditionally, we offer high pressure DSC analysis, using a pressured closed crucible (500 bar @ 500 °C), which is optimal for providing insight into low-vapour pressure liquids.
