Limitations of PTFE:
Non-melt processable material.
Low tensile yield strength and modulus (when compared to PEEK, PPS and LCP)
High wear behaviour in unfilled state.
Not weldable.
Sensitivity to creep and abrasion.
Low radiation resistance.
Teflon™ is a synthetic polymer, which is containing carbon and fluorine – this, therefore, makes it Polytetrafluoroethylene. YES, Teflon™ is a PTFE. Teflon™ is a trademarked name for PTFE, owned by Chemours.
The expanded PTFE sheet is made from 100 percent virgin PTFE and is exceptionally compressible. It is a food-safe product with great chemical resistance, making it a preferred sealing material in the food, beverage, and pharmaceutical sectors.
