Why is PP rated this way to Chlorine Dioxide?
PP has limited resistance to Chlorine Dioxide. Short-term exposure may be acceptable, but prolonged contact is not recommended.
⚠️ When NOT to use PP
Avoid using Polypropylene with concentrated oxidizing acids, chlorinated solvents, and aromatic hydrocarbons. Becomes brittle below 0°C.
