Fluorinated bottles have the special quality of withstanding a wide range of corrosive chemicals. Regular HDPE containers react with chemicals which lead to corrosion and reduced shelf live. The thin coating of PTFE material inside the fluorinated bottle acts as an insulation layer between the HDPE material and chemical within. Because of the special barrier layer, the bottles have the following exceptional properties: No Chemical Reaction! No Evaporation! No Corrosion! No infusion!
