Modified PTFE can be considered a second-generation PTFE. While retaining the exceptional properties of PTFE, it offers significantly improved properties:
- lower deformation under load (cold flow reduced by a factor of three)
- denser polymer structure
- reduced permeation of chemicals and gasses down to half of the standard PTFE value
- smoother surfaces on machined parts
- higher transparency
- excellent weldability
