OVERVIEW of Chemours® NXT 70 PTFE |
Chemours® NXT 70 PTFE is a chemically modified polytetra-fluoroethylene polymer. When properly processed, Chemours® NXT 70 exhibits the superior properties typical of the fluoropolymer resins: nonaging characteristics, chemical inertness, heat resistance, toughness and flexibility, low coefficient of friction, nonstick characteristics, negligible moisture absorption, and weather resistance.
In addition, Chemours® NXT 70 offers weldability, improved resistance to deformation under load, increased resistance to permeation of chemicals, and a higher dielectric breakdown voltage. This grade exhibits minimal sagging (typical of modified PTFE) in billets as large as 350 kg (800 lb).
