Ultra High Purity Materials

Fluoroplastics  These plastics all contain fluorine which is highly electro negative making them inert and chemical resistant They also tend to handle high temperatures and are very pure.

  • ETFE (Ethylene Tetrafluoroethylene) - is a partially fluorinated thermoplastic. It is resistant to most chemicals except concentrated oxidizing acids at elevated temperatures, alkali amines, certain organic solvents, alkali metals at ambient temperature, fluorine at elevated temperatures, and certain halogenated compounds.
  • PTFE-M (Polytetrafluoroethylene) Is similar to PTFE but is chemically modified with perfluoropropyl vinyl ether to make it melt flow processable. It is chemically resistant to virtually all chemicals except alkali metals and fluorine at elevated temperatures. PTFE-M is also less permeable then PTFE, making it the material of choice for the most severe, highest temperature corrosive environments. Available as a bonded sheet lining with a maximum service temperature of 230°F.
  • FEP (Fluorinated ethylene propylene)  A fully fluorinated thermoplastic which is chemically inert. FEP is subject to attack at ambient temperature by alkali metals, alkali metal organics and fluorine.
