GE Ultem 9085 Resins for Lighter Weight Aircraft Interior Parts
GE launches FST-compliant Ultem 9085 resins with improved flow properties for thinner, lighter weight aircraft interior parts.
To help the aerospace industry boost fuel efficiency, performance, and safety, this new new flame-retardant Ultem 9085 resins material for aircraft interiors from GE Plastics, offers better flow and ductility than GE’s Ultem 9075 resin – the previous industry standard – to enable thinner-wall parts with excellent impact strength.
Further comparing the two materials, new Ultem 9085 resin can reduce part weight by 5 to 15 percent via thinner walls, supporting the goal of lower fuel consumption. At the same time, Ultem 9085 resin delivers the highest modulus of any Ultem resin grade, providing enhanced stiffness to ensure excellent application durability. These greatly improved properties make the new GE product a top choice for demanding applications such as decompression grilles, window reveals, and personal service units.
According to Joseph F. Jahn, president and CEO of Vaupell, a Seattle, Washington, USA based plastics molder and Tier 1 aircraft supplier, “Vaupell has worked closely with GE Plastics for several decades supporting the development of resins for the aerospace industry. GE’s new Ultem 9085 resin material demonstrates distinct improvements in processability and physical properties performance compared to the company’s Ultem 9075 resin.”
Like all Ultem resin grades, the new material is inherently flame-retardant, offering full flame/smoke/toxicity (FST) compliance including OSU heat release of less than 55/55. Ultem 9085 resin provides up to 25 percent improvement in ductility and a threefold improvement in flow compared to Ultem 9075 resin, enabling a reduction in both aircarft part weight and the amount of resin required. It also delivers good chemical resistance. The new material is lighter in color than its predecessor, making it easier to achieve specific aesthetic effects.“The aerospace industry is constantly looking for new ways to reduce part weight for better fuel efficiency, and using thinner-wall parts are a great approach,” said Ann Delvin, product manager, High Performance Products (HPP) at GE Plastics. “We improved upon our workhorse grade, Ultem 9075 resin, with a new material that allows suppliers to create large, thin-wall parts with excellent impact resistance and stiffness. Ultem 9085 resin can play an important role in decreasing weight while delivering high performance in a wide range of applications.

Last november was a memorable month for us at Matbase, we passed the milestone of 1000 visitors per day. So I guess we were not that far of when we thought it would be a good idea to make the material database we used as students during our stay at the Delft University of Technology accessable to other people. Apparently, people appreciate the easy way they can lookup the material properties and how we present the data.
