Compatibility Rating
At 20°C
Fair
Limited resistance - short-term exposure only
At 50°C
Poor
Not recommended - significant degradation expected
Why is HDPE rated this way to Benzene?
HDPE has limited resistance to Benzene. Short-term exposure may be acceptable, but prolonged contact is not recommended.
⚠️ 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.
