Polypropylene Glass Transition Temperature: A Comprehensive Guide For Processing And Performance Optimization
Polypropylene’s glass transition temperature (Tg) marks the transition from a rigid, glassy state to a soft, rubbery state. It is influenced by molecular structure, crystallinity, and processing conditions. Tg affects polypropylene’s processability, mechanical properties, thermal stability, and dimensional accuracy. Measurement techniques like DSC and DMA help determine Tg accurately. Factors such as molecular weight, crystallinity,…
