To ensure safe storage of gases and liquids with varying levels of corrosiveness, storage tanks often require internal fluoropolymer linings or coatings. Depending on the chemical properties and working conditions, such as acids, alkalis, or refined substances, different fluoropolymer materials are selected to provide effective corrosion resistance.

• Corrosion resistance
• High purity
• Non-stick
• Low static discharge
• Low friction

• Semiconductor
• Petrochemical
• Pharmaceutical
• Agrochemical
• Lithium battery

To meet the strict purity and corrosion resistance requirements of semiconductor and electronics applications, storage vessels are lined with high quality imported fluoropolymer sheets such as PTFE, N-PTFE, and PFA. Materials are sourced from trusted brands including Daikin and DuPont.
