You can run chlorine in polypropylene (PP) for short periods or low concentrations, but long-term exposure, especially with hot or pressurized chlorinated water, causes degradation, cracking, and failure, making materials like PVDF or CPVC generally better for continuous chlorine service. While PP resists many chemicals, chlorine's oxidizing power breaks it down, leading to premature system failure, so specific use depends heavily on concentration, temperature, and time.
