Ausimont introduces fibers for melt blowing.

A new application for the "Halar" fluoropolymer has been developed by Ausimont USA, Morristown, NJ. Traditionally used as a wire and cable covering, Halar ethylene-chlorotrifluoroethylene (ECTFE) is the first commercially available fluoropolymer that can be melt blown, according to the company. The primary application for melt blown Halar fibers is in filtration, with efficiencies of more than 95% possible with electrostatic charging.

Halar is chemically inert, resists attack by most corrosive chemicals and organic solvents, has a broad thermal operating range and is resistant to fire. It also maintains all of its properties after being exposed to irradiation sterilization techniques.

In recent tests at the University of Tennessee, Halar produced soft webs with good strength in the cross machine direction, while machine direction strength could be improved by calendering. Other potential applications in addition to filtration include medical, membrane and asbestos replacement markets.
