AvaSpire® AV-481 is an unreinforced PAEK (polyaryletherketone) that offers improved ductility and impact strength relative to PEEK while offering similar or superior melt processability to high melt flow PEEK that is available on the market. Chemical resistance and environmental stress cracking resistance of AV-481 are also on par with that of unreinforced PEEK. This product has been specifically formulated for applications requiring an excellent balance of chemical resistance and mechanical toughness along with very high melt flow characteristics to allow filling of very thin and long flow length parts like cable ties. The heat resistance of this grade is also quite high with a heat distortion temperature in excess of 200°C and very  good long term oxidative stability at elevated temperatures. This combination of properties makes AV-481 well-suited for applications in automotive, aerospace, electrical/electronics, and other industrial uses. 
AvaSpire® AV-481 is an injection molding grade and can be easily processed by typical injection molding methods using standard equipment. The material is available in beige (AV-481 BG15). Because the material is naturally lighter in color than typical PEEK resin, AV-481 provides greater versatility in its ability to be colored.
