Why is HDPE resistant to Dmf?
HDPE shows excellent resistance to Dmf 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.
