Excellent
Excellent resistance - recommended for continuous use
At 50°C (122°F)
C
Fair
Limited resistance - short-term exposure only

Why is PP resistant to Acetic Anhydride?

PP shows excellent resistance to Acetic Anhydride due to its semi-crystalline structure providing good chemical resistance to acids, bases, and organic solvents at moderate concentrations.

⚠️ When NOT to use PP

Avoid using Polypropylene with concentrated oxidizing acids, chlorinated solvents, and aromatic hydrocarbons. Becomes brittle below 0°C.
