What are the differences in chemical stability between PVC and polypropylene?
PVC (polyvinyl chloride) and polypropylene are two widely used plastics, but they exhibit distinct differences in chemical stability. PVC is known for its excellent resistance to acids, bases, and oils, making it suitable for chemical storage and piping. However, it can degrade under prolonged UV exposure unless stabilized with additives.
Polypropylene, on the other hand, offers superior resistance to organic solvents and high temperatures, but it is less resistant to strong oxidizing agents compared to PVC. Both materials have unique advantages depending on the application, with PVC excelling in corrosive environments and polypropylene performing better in high-heat scenarios. Understanding these differences helps in selecting the right material for specific industrial or consumer needs.
