The story of DuPont Teflon® PFA HP Plus is one of a continuing focus on serving the semiconductor industry with the purest and most reliable materials. As the industry's requirements have evolved, becoming ever more demanding, DuPont has led the development of improved generations of our Teflon® PFA fluoropolymers to meet these needs, including:
- Teflon® PTFE (1938), TFE polymerization
- Teflon® PFA (1973, perfluoroalkoxy structure
- Teflon® PFA EG (1986), less reactive ammonia end groups
- Teflon® PFA HP (1989), patented, fully fluorinated, low contamination potential
- Teflon® PFA 451 HP (1995), nucleated, smaller spherulites
- Teflon® PFA HP Plus (2000), patented, smallest spherulites, fluorosurfactant resistance and improved mechanical reliability.
