Syensqo PAEK AvaSpire AV-722 SL30 Polyaryletherketone Pellets

Syensqo PAEK AvaSpire AV-722 SL30 is a wear resistant grade of AvaSpire® polyaryletherketone (PAEK) designed to provide low wear rates in both non-lubricated and lubricated environments. In addition to the outstanding wear resistance, the resin also offers the outstanding combination of ultra performance attributes commonly known for PEEK. These include: chemical resistance, mechanical strength and stiffness, even at elevated temperatures, as well as long-term and high-temperature thermal-oxidative stability. AV-722 SL30 is formulated with the ternary anti-friction/anti-wear additive system comprised of carbon fiber, graphite, and polytetrafluoroethylene (PTFE.) It offers wear resistance performance comparable to PEEK grades with this modifier system while being more cost-effective.

This resin is a low melt flow (high viscosity) grade designed for use in injection molding of less intricate shapes or parts. By virtue of its high viscosity at low shear rates, the resin has high melt strength, and, as such, is extrudable into stock shapes such as rods, pipe, tubing and profile. The resin can be melt processed using conventional equipment and techniques.

Potential applications for AV-722 SL30 include bushings, bearings, wear strips, wear rings, rollers, and other parts or components where sliding friction is encountered. The resin is black in color in its natural state.

Customized High-Performance Polyketones

AvaSpire PAEK (polyaryletherketone) is a family of high-performance polyketones tailored to fill cost and performance gaps between PEEK and other high-performance polymers. For example, ductility and toughness can be significantly improved versus comparable grades of PEEK, delivering 20% higher tensile elongation at yield and double tensile elongation at break values.

Higher Stiffness than PEEK from 150°C to 200°C (302°F to 392°F)

AvaSpire AV-651 has a modulus twice that of unfilled PEEK at 180°C (356°F). AvaSpire AV-481 provides even higher modulus, close to 3X the modulus of unfilled PEEK (see chart below). AvaSpire Glass AV-600 and AV-400 series analogs likewise provide higher modulus compared to glass filled PEEK at the equivalent level of glass fiber loading.

Automotive Applications:

All three series of AvaSpire PAEK (400, 600 and 700) constitute good candidates for utilization in automotive under the hood and powertrain applications. All three series exhibit broad resistance to all automotive fluids, even at elevated temperatures up to 150°C (302°F). Applications in automotive include structural uses, where AV-750 GF40 has been successfully positioned in a number of applications. The wear resistant SL series of AV-700 products can be used in seal rings, bushings and bearings. Lastly, the 400 series is ideally suited for injection moldable thin walled structural parts with high strength to weight ratio and attractive economics.

Healthcare Applications:

The AvaSpire PAEK 600 series of products has demonstrated a track record of success in healthcare applications for over ten years now, notably in reusable sterilizable surgical instruments and devices. The combination of high mechanical performance, combined with a robust chemical resistance to a wide range of sterilization media have allowed these AvaSpire PAEK grades to become viable alternatives to stainless steel for many uses. Most AV-600 grades exhibit outstanding cleanliness and inertness attributes for patient safety and are ISO 10993 certified.

In addition to allowing highly functional and lightweight components in the operating room, they also offer improved comfort and ergonomics, not only for patients, but for health care providers as well.

Oil & Gas Applications:

AvaSpire PAEK finds uses in sealing components for compressors in the oil and gas industry. The higher mechanical and temperature performance relative to PEEK in the 150-190°C (302-374°F) temperature regime, coupled with high toughness and chemical resistance make the AvaSpire PAEK 600 series excellent candidates in a wide variety of compressor applications.

erospace applications:

AvaSpire PAEK products are very valuable in aerospace applications as their performance features of fatigue and creep resistance, chemical resistance and hot-wet performance are an excellent match to the industry's key requirements for light and medium duty structural applications. The excellent flame, smoke and toxicity characteristics of most AvaSpire PAEK grades are also key to their success in aircraft/aerospace. Last but not least, the high flowability characteristics combined with high strength and stiffness allow for thin walled injection molded parts that combine structural integrity without compromising lightweighting constraints and considerations.
