Acetaldehyde Resistance of LDPE

Is LDPE compatible with Acetaldehyde? See the chemical resistance rating below.

Compatibility Rating

At 20°C (68°F)
B
Good
Good resistance - suitable for intermittent contact
At 50°C (122°F)
D
Poor
Not recommended - significant degradation expected

Why is LDPE resistant to Acetaldehyde?

LDPE shows good resistance to Acetaldehyde due to its flexible polymer chains that resist attack from most aqueous solutions and inorganic chemicals.

⚠️ When NOT to use LDPE

Avoid using Low-Density Polyethylene with strong oxidizers, chlorinated solvents, and aromatic compounds. Temperature limit is approximately 60°C.

🌡️ Temperature Note

Performance degrades significantly at higher temperatures — rated Good at 20°C but only Poor at 50°C. For elevated temperatures, consider a more resistant material. Max service temp: 60°C.

🔄 Better Alternative?

Consider: HDPE (stronger) or PP (higher temp). View all materials for Acetaldehyde →
