Product Details

Quadrant’s Nylatron^® 66 SA FST is a specialized polymer solution created for aircraft interior use. It was developed as a semi-finished engineering plastic and is available in rod and sheet form, which makes it easier to integrate into many interior parts. Thanks to its fire, smoke, and toxicity (FST) resistance, the material is suitable for service at temperatures up to 175 ºC.

The material is especially well suited to applications where metal components or other demanding polymers have typically been selected in the past. Parts such as brackets, seal bushings, slide rails, and duct seals can benefit from the combination of low weight, machining ease, and wear-friendly behavior that Nylatron^® 66 SA FST provides.

Quadrant introduced this product as a commercially practical choice for aircraft interior applications, and it is positioned as a safe material option for engineers who need compliance as well as reliable performance. Nylatron^® 66 SA FST has passed tests to comply with Federal Aviation Regulations FAR 25.853, becoming the first engineering plastic shape to achieve this standard.

In real-world use, the material can help simplify part design where a lightweight substitute for aluminum is preferred, while still maintaining the required interior performance profile. Its low noise characteristics and compatibility with moving or contact-based parts also make it valuable in areas where smooth operation matters.

Typical Applications

• Interior aircraft brackets
• Seal bushings
• Slide rails
• Duct seals

For aircraft interior projects that require a proven balance of compliance, weight reduction, machinability, and durability, Nylatron^® 66 SA FST offers a dependable material choice. Its combination of FST performance and practical processing advantages makes it especially relevant where safety and efficiency must work together.
