Why is LDPE resistant to Isooctane?
LDPE shows excellent resistance to Isooctane due to its flexible polymer chains that resist attack from most aqueous solutions and inorganic chemicals.
⚠️ When NOT to use LDPE
Avoid using Low-Density Polyethylene with strong oxidizers, chlorinated solvents, and aromatic compounds. Temperature limit is approximately 60°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: 60°C.
🔄 Better Alternative?
