Screws and Fasteners
High-Performance Component Lightweighting
A Lightweight Design to Improve Aircraft Performance and Safety
The contribution of aviation to global warming has led to focus on energy efficiency and reduced fuel consumption. Specialty Polymers offers a wide range of alternatives to metals for all kinds of screws and fasteners for today’s lightweighting design needs.
Specialty Polymers offer excellent mechanical strength and high temperature performance. They also have outstanding friction and wear resistance and have a broad chemical resistance to withstand aircraft fluids, insecticides and cleaning agents. They all have inherent flame-retardant properties and can be manufactured into tight tolerance parts for precision designs.
- Torlon® PAI retains its toughness, high strength and high stiffness at temperatures up to 275°C (525°F), in both dry and lubricated environments. It also exhibits outstanding creep and is ideally suited for harsh environments with its chemical resistance to strong acids and most organics.
- KetaSpire® PEEK offers excellent strength, stiffness and fatigue resistance plus one of the best levels of chemical resistance among plastics. This combination with a continuous-use temperature of 240°C (464°F) makes it ideal for metal replacement in the most severe end-use environments.
- AvaSpire® PAEK is a versatile family of polymer grades tailored to provide new high-performance, cost-effective solutions. The AV-600 series delivers a range of distinctive performance attributes with more attractive economics compared to PEEK. While the AV-700 series offers comparable performance to PEEK at up to 30% lower cost
