"PP" typically stands for "polypropylene," a type of plastic commonly used in packaging, textiles, and automotive parts. "PCM" can refer to "phase change material," which is used for thermal management and energy storage by absorbing and releasing heat during phase transitions. In specific contexts, "PP PCM" might denote a composite material or a product involving both polypropylene and phase change materials, often aimed at enhancing thermal performance or insulation.
