At 50°C
Fair
Limited resistance - short-term exposure only
Why is HDPE resistant to Diesel Fuel?
HDPE shows excellent resistance to Diesel Fuel 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?
