For most DSC users, when studying the thermophysical properties of materials, we usually pay more attention to the heating curve segment

The following examples are based on experimental results measured on a DSC3 device equipped with mechanical refrigeration

Case1: The cooling section program distinguishes recycled PP and unused PP

What is PP recycled material? PP recycled material is also polypropylene recycled material

The method of this case is a cycle from 40 to 180 °C with a heating and cooling rate of 10 K/min, and the mass of both samples is 5-6 mg

Liquid crystal (LC) and liquid crystal polymer (LCP) generally refer to organic compounds that exhibit an intermediate phase between solid phase and liquid phase within a certain temperature range

The case in the figure below is the phase transition process of cholesteryl myristate at a heating and cooling rate of 10K/min.
