Materials Innovations for Aerospace Industry Are Focus of Quadrant EPP Development Efforts  


VREDEN, Germany—Quadrant Engineering Plastic Products (Quadrant EPP), a manufacturer of semi-finished engineering plastic materials, has developed a number of material innovations for the aerospace industry that were recently on display at the Farnborough International Air Show. Among them were the Nylatron® FST, a polyamide product designed specifically for aircraft interiors.

According to a release from Quadrant EPP, Nylatron FST has unique features that are reported to make it the first engineering plastic product of its kind available as semi-finished shapes (rods and sheets). Fire, smoke and toxicity (FST) retardant capabilities enable Nylatron® FST to withstand extreme temperatures up to 120º C, according to a release from Quadrant. The material is particularly suitable for any kind of application in aircraft interiors, where metal parts—such as brackets, seal bushings, slide rails, and duct seals—or high performance polymers have traditionally been specified. The material is supported by extensive testing and complies with Federal Aviation Regulations FAR 25.853, making it the first engineering plastic shape to achieve this standard, Quadrant reported.

“Plastics aren’t new to aircraft interiors, but we see a lot of products that are, from our perspective, chosen specifically for their fire, smoke, and toxicity (FST) performance levels,” commented Frank Johänning, global market manager for aerospace at Quadrant Engineering Plastic Products, in the release. “Ultimately, Quadrant’s overall target is to offer improved solutions through advanced thermoplastic materials that allow a higher level of functional integration.

"To strengthen our portfolio of solutions for metal to plastic conversion and to follow the trend for mechanically higher loaded plastic solutions, we have just extended our offer to supply the global market of structural elements in aircraft construction,” Johänning continued. “As a supplement to our portfolio, we are now launching Quadrant’s HLS-Series: Composite Materials for High Load Solutions. These are special carbon fiber-reinforced composite materials [Ketron® CC PEEK, Duratron® CC PEI, Techtron® CC PPS and Kyron® MAX] available in various thicknesses and geometries, offering endless design opportunities to engineers.”
