ECTFE / Halar® Compression Molding

ECTFE (ethylene-chlorotrifluoroethylene) is a partially fluorinated, semi-crystalline, melt-processible polymer best known by the brand name Halar®.

ECTFE / Halar® Properties

1. •High tensile strength
   

2. •Ductile, welded corner seams will flatten before breaking
   

3. •Extraordinarily high impact strength at temperatures from -100 °F to +300 °F
   

4. •Resists permeation by chemicals in the pH 0-14 range, suitable for wetted parts
   

5. •Permeation resistance to chlorine gas, oxygen and carbon dioxide 10-100 times better than PTFE
   

6. •Excellent chemical resistance over a wide temperature range
   

7. •Resists semiconductor process chemicals
   

8. •Resists strong polar solvents such as DMF and NMP
   

9. •Ultrapure, very low extractable and leaching levels for demanding semiconductor applications
   

10. •Low outgassing
    

11. •Exceptionally smooth surface
    

12. •Easier to fabricate than most fluoropolymers, can be welded, machined, thermoformed and bonded
    

13. •Easy to fabricate with conventional welding equipment, with extremely strong welds
    

14. •Very good sliding properties
    

15. •High density
    

16. •Good insulation properties
    

17. •Very good weather resistance
    

18. •Food safe
    

19. •Self-extinguishing
    

20. •Approved and listed to the FM Global 4910 Clean Room Fire Safety Protocol as a fire-safe material for clean-room equipment
    

21. •The cost of fire-safe tools can be easily offset by eliminating the purchase and installation costs of fixed fire-suppression equipment
    

22. •Limited protection against stress cracking above 284 °F
