HALAR ECTFE

Halar ECTFE from SAN DIEGO PLASTICS

FlametecHalar*ECTFE   (Ethylene Chlorotrifluoroethylene) is an ultra-pure  fluoropolymer that is a tough engineering thermoplastic with a balance of physical and chemical properties that qualify it for high performance service in a wide range of applications. It is mechanically both strong and tough, exhibiting high dielectric strength, and can be used in applications over a broad temperature range. As a fluoropolymer, it is highly resistant to most environmental conditions, including corrosive chemicals and organic solvents, strong acids, alkaline, peroxide and SC1 and SC2 chemistries, and aqueous caustics for handling wet or dry chlorine, bromine, and other halogens.

        Note:  Halar 453 Clear has been discontinued.                

Key Benefits Features Benefits
Halar-b2.jpg (39403 bytes) Purity Halar has a very low extractable and leaching levels for the most demanding semiconductor applications.
Weldability Easy to fabricate with conventional welding equipment. Extremely strong welds.
Strength High tensile properties and it is very ductile.

  

  

Halar-b1.jpg (28490 bytes) Economics The cost of Halar is easily offset by the expense that would normally be incurred by fire suppression equipment.
Fire Safe Accepted in accordance to FM4910, fire safe materials for clean room construction.
Extruded Sheet Offers the best gauge consistency, surface and tolerances.

Chemical Resistance
ECTFE has excellent resistance to strong acids such as sulfuric, nitric, hydrochloric and hydrofluoric over a wide temperature range. ECTFE can also easily handle powder bleaching agents such as sodium hydroxide and potassium hydroxide that would stress crack PVDF. ECTFE 901 can handle strong polar solvents that would dissolve PVDF such as n-Methyl pyrrolidone and dimethyl formamide.
