Why is HDPE rated this way to Styrene?
HDPE is not recommended for use with Styrene. Significant degradation or failure is expected.
⚠️ 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.
