| Teflon PFA 350 |
 |
Teflon PFA 350 is a general-purpose resin available in clear, 2.5-mm(0.1-in.) pellets.
Compared with other grades of Teflon PFA, its most unique features are a relatively low flow rate, greatly increased flex life, and enhanced resistance to environmental stress cracking.
Teflon PFA 350 and the other Teflon PFA(perfluoroalkoxy) fluoropolymer resins combine theprocessing ease of conventional thermoplastics with properties similar to those of polytetrafluoroethylene(PTFE).
They have high melt strength, stability at high processing temperatures, and resistance to creep at high service temperature.
Teflon PFA 350 is preferred when extended service is required in hostile environments involving chemical, thermal, and mechanical stress.
For a given process, its high melt strength and thermal stability can be used to improve rates.
Compared with other fluoropolymers, its creep resistance at its high service temperatures provides a superior balance and level of end-use properties. |
