Why is LDPE resistant to Hydrochloric Acid?

LDPE shows excellent resistance to Hydrochloric Acid 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.
