Frequently asked questions about ULTEM™ 9085
What is ULTEM™ 9085?
ULTEM 9085 is a polyetherimide-based thermoplastic. It is known for its high strength-to-weight ratio and flame, smoke and toxicity behavior that meets aircraft interior standards (FAR 25.853). It is used in industrial FDM systems for aircraft ducts, cabin components and train interior parts.
Is ULTEM™ 9085 heat resistant?
The heat deflection temperature (0.45 MPa) of ULTEM™ 9085 is about 178 °C. This is very high; suitable for demanding thermal environments.
Can ULTEM™ 9085 be used outdoors?
It usually performs well in short and medium-term outdoor use; for parts exposed to direct sunlight for long periods, UV-resistant materials such as ASA are a better fit.
Which parts are made with ULTEM™ 9085?
ULTEM™ 9085 is typically used in applications such as aircraft cabin components, air ducts, train and bus interior parts.
Which material can be used instead of ULTEM™ 9085?
