The bulk density of polypropylene granules can vary depending on several factors such as the grade of polypropylene, the size and shape of the granules, and whether they are filled or unfilled. Generally, the bulk density ranges from about 0.4 to 0.6 g/cm³. This measurement is crucial for processing and handling in industries as it affects the storage, transportation, and feeding into machines for manufacturing processes. Higher density polypropylene might indicate a higher molecular weight or the presence of fillers, which can enhance certain properties like stiffness or thermal conductivity. When working with polypropylene granules, taking into account their bulk density is essential for optimizing the manufacturing process and product performance.

Polyvinyl chloride, commonly known as PVC, is a type of plastic widely used in construction, piping, and electrical insulation due to its robustness and versatility. An important property of PVC is its thermal conductivity, which affects how well it can transfer heat. Typically, PVC has a low thermal conductivity compared to metals, making it an inefficient conductor of heat. This characteristic can actually be beneficial in applications where thermal insulation is required. The thermal conductivity of PVC generally ranges from 0.14 to 0.28 W/(m·K), indicating that it does not easily allow the flow of heat. This makes PVC an excellent material for insulating cables, pipes, and in constructing windows and doors where minimizing heat transfer is desired. However, for applications requiring efficient heat dissipation, PVC might not be the most suitable material without modifications or the addition of thermal conductive fillers.
