Halar (ECTFE) Coating
WHAT IS HALAR® FLUOROPOLYMER?
HALAR® is essentially a 1:1 alternating copolymer of ethylene and chlorotrifluoro-ethylene (CTFE). By weight, it contains about 80% CTFE, one of the most chemically resistant materials that can be used to make a polymer.
Though CTFE homopolymers are excellent materials, they are difficult to fabricate into complex shapes. By copolymerizing CTFE with ethylene, HALAR® combines the chemical resistance of CTFE-based materials with easy processability.
WHY IS HALAR® USED FOR CHEMICAL APPLICATIONS?
HALAR® is one of the most chemically resistant polymers available today.
It possesses the following characteristics:
- Suitable for the most demanding applications:
- Mechanically tough with excellent abrasion and impact resistance
- Continuous use to 300º F in many applications Excellent release properties
- Extremely smooth surface
- Dimensionally stable
- Low cold flow
