AvaSpire® AV-651 is an unreinforced polyaryletherketone (PAEK) that offers more ductility and impact strength than PEEK, with higher chemical and environmental stress cracking resistance than AvaSpire® AV-650. It has been specifically formulated for applications requiring a balance of chemical resistance and mechanical strength along with good part aesthetics, bridging the performance gaps within the ultra polymers space. 
These properties make it well-suited for applications in healthcare, transportation, electronics, chemical processing and other industrial uses. AvaSpire® AV-651 can be easily processed by typical injection molding and extrusion methods using conventional processing equipment.
