Why is HDPE resistant to Sodium Hypochlorite?
HDPE shows good resistance to Sodium Hypochlorite 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 Good at 20°C but only Fair at 50°C. For elevated temperatures, consider a more resistant material. Max service temp: 80°C.
