Polyvinyl Chloride, or PVC, is a popular synthetic plastic polymer used in a wide range of products due to its durability, cost-efficiency, and versatility. By its nature, PVC is non-porous, meaning it does not have pores through which liquids or gases can pass. This characteristic makes it an ideal choice for applications where a waterproof or airtight material is required, such as in plumbing pipes, medical devices, and construction materials. However, PVC's surface can be modified to become porous for specific applications, like filtration, through special manufacturing processes. These processes create microporous structures within the PVC, allowing it to achieve desired levels of permeability for the task at hand.

Polypropylene was discovered in 1954 by Italian chemist Giulio Natta and his team, following earlier work by Karl Ziegler who developed the Ziegler-Natta catalyst. Ziegler had already invented a process for polymerizing ethylene into polyethylene. Natta's breakthrough involved applying similar catalytic methodologies to propylene, resulting in the creation of polypropylene, a thermoplastic polymer. This discovery was significant for creating a plastic with high resilience and melting point, making it suitable for a vast range of uses, from packaging to automotive components. The innovative work of Natta and Ziegler fundamentally transformed the plastic industry, earning them the Nobel Prize in Chemistry in 1963.

Polypropylene (PP) is a thermoplastic polymer widely used due to its excellent chemical resistance and mechanical properties. When considering whether PP can be used with acetone, it's important to understand the interaction between the two. Acetone is a powerful solvent known for dissolving various plastics. However, polypropylene exhibits remarkable resistance to many solvents, including acetone. Typically, acetone does not dissolve or significantly affect polypropylene at room temperature. This makes PP an ideal choice for applications where exposure to acetone is expected. Despite this, prolonged or high-temperature exposure may cause slight swelling or stress-cracking. For best results, testing specific PP grades under intended conditions is recommended to ensure compatibility. Overall, polypropylene's resistance to acetone makes it a suitable material for use in environments where acetone contact is anticipated.
