Benzaldehyde Resistance of HDPE

Is HDPE 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)
C
Fair
Limited resistance - short-term exposure only

Why is HDPE resistant to Benzaldehyde?

HDPE shows excellent resistance to Benzaldehyde due to its tightly packed molecular structure and chemical inertness to most acids, bases, and salts.

⚠️ When NOT to use HDPE

Avoid using High-Density Polyethylene with strong oxidizing acids (nitric, chromic), chlorinated solvents, and aromatic hydrocarbons. Maximum service temperature is around 80°C.

🌡️ Temperature Note

Performance degrades significantly at higher temperatures — rated Excellent at 20°C but only Fair at 50°C. For elevated temperatures, consider a more resistant material. Max service temp: 80°C.

🔄 Better Alternative?

Consider: PP (higher temp) or PTFE (universal). View all materials for Benzaldehyde →
