The use of a DSC for the analysis materials is a common technique. In this application, the chip DSC was used to measure PP pellets. Using melt enthalpy and behavior.
PP, short for polypropylene, is one of the most commonly used thermoplastic polymers. It consists of the monomer propylene, belongs to the group of polyolefins, and has properties largely similar to those of polyethylene, but is somewhat harder and more heat-resistant (TM_PE ~ 100 °C–130 °C; TM_PP ~ 150 °C–170 °C).
It is frequently used for labeling and packaging, but also for piping systems. The Melting point is the simplest way to characterize PP. The onset point varies by approximately 10 K among different manufacturers.
