Why is LDPE resistant to Calcium Hypochlorite?
LDPE shows excellent resistance to Calcium Hypochlorite 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.
