Plastic is a broad term that refers to a wide range of synthetic or semi-synthetic organic compounds that can be molded or shaped into various forms. There are many different types of plastics available, each with its unique set of properties and characteristics.
PP, on the other hand, is a specific type of plastic, which stands for polypropylene. PP is a thermoplastic polymer that is widely used in various applications due to its unique combination of properties, including high stiffness, chemical resistance, and low density.
In essence, PP is a type of plastic, but not all plastics are PP. There are many other types of plastics, such as polyethylene (PE), polystyrene (PS), polyvinyl chloride (PVC), and many more, each with its unique properties and applications.
Therefore, it is important to understand the specific type of plastic being used in a particular application to ensure that it meets the required properties and performance characteristics.
