Benzaldehyde Resistance of Polypropylene (PP)

Is Polypropylene (PP) compatible with Benzaldehyde? See the chemical resistance rating below.

Compatibility Rating

At 20°C (68°F)
A
Excellent
Excellent resistance - recommended for continuous use
At 50°C (122°F)
D
Poor
Not recommended - significant degradation expected

Why is PP resistant to Benzaldehyde?

PP shows excellent resistance to Benzaldehyde 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.
