DuPont Performance Polymers Kalrez® PV8070 Fluoroelastomer

DuPont™ Kalrez® PV8070 perfluoroelastomer parts are a black product for PV cell manufacturing processes requiring high temperature resistance including doping for n-type layer formation (bulk c-Si), diffusion for diselenide thermal implantation (CGIS) and TCS-based thermal CVD for poly-silicon feedstock production. It exhibits outstanding thermal stability and has excellent (low) compression set and outgassing properties. It also offers excellent resistance to both chlorine and fluorine gas as well as other dry process chemistry. Kalrez® PV8070 perfluoroelastomer parts have excellent mechanical strength properties and are well suited for both static and dynamic sealing applications. A maximum continuous service temperature of 325 °C is suggested. Short excursions to higher temperatures may also be possible.
