Example of AFLAS Molded Parts
Wire & Cable
• Heat resistance • Chemical resistance • Chemical resis4vity
• Robots
• Express train, automo4ve
• Cable for furnace
Example of AFLAS Molded Parts
Oil Field (oil rig parts)
• Oil resistance • H2S resistance • High strength
AFLAS has long been used for oil field applica4ons
Example of AFLAS Molded Parts
LCD – Semiconductor Process
• Chemical resistance for these processes:
• TMAH, NMP, NaOH, Aq Ammonia, etc.
• Plasma resistance
Example of AFLAS Molded Parts
Food & Beverage Produc4on Process
• Resistance to steriliza4on
• Steam, sodium hypochlorite (NaCIO), peroxyace4c acid are typical
• Low odor aier contact
