Compatibility Rating
At 20°C (68°F)
Fair
Limited resistance - short-term exposure only
At 50°C (122°F)
Poor
Not recommended - significant degradation expected
Why is PP rated this way to Chlorine Water?
PP has limited resistance to Chlorine Water. 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.
