ULTEM™ LTX300A Non Reinforced High Flow FST PEI Resin

ULTEM™ LTX300A PEI Resin is developed with Aerospace Safety at its core, combining High Flow Processing with low Emissions Performance in a Non-Reinforced Polyetherimide Blend. Designed for Interior Aircraft Use, the Material balances Manufacturability with strict Flame, Smoke, and Toxicity Requirements, allowing Engineers to meet compliance without sacrificing design flexibility.

What sets this Grade apart is its ability to deliver precise Molding Performance for Thin-Wall and Complex Components. The enhanced Flow Behavior enables smoother Material Distribution, supporting efficient Production while ensuring consistent Part Geometry and Surface Quality. This allows Manufacturers to achieve both Productivity and Accuracy in high-demand Aerospace Manufacturing Environments.

Safety Performance remains a defining strength. ULTEM™ LTX300A PEI Resin meets FAR 25.853 Requirements, limiting Flame Spread, Smoke Generation, and Toxic Emissions. In addition, the Material aligns with Halogen-Free Standards including IEC 61249-2-21, IPC 4101E, and JEDEC JS709B, reinforcing its suitability for Safety-Critical Aerospace Systems.

Thermal Stability ensures Components maintain Mechanical Integrity under Elevated Temperature Conditions. Combined with inherent Flame Retardant Properties, the Material achieves UL94 V0 Rating from 0.75 mm to 3.00 mm, supporting reliable Operation in environments where Fire Performance is essential.

While optimized for Aerospace Applications, the Material also delivers dependable Mechanical Strength and Dimensional Stability, allowing it to perform consistently under Structural and Environmental Stress. This ensures long-term Reliability across service conditions involving Vibration, Temperature Variation, and Mechanical Loading.

Available in Transparent Amber and Opaque Colors, ULTEM™ LTX300A PEI Resin supports both Functional and Design Requirements. This versatility allows integration into visible Interior Components as well as concealed Structural Parts, depending on application needs.

Typical Applications include Aircraft Interiors, Electrical Enclosures, and Specialty Components where Low Emissions, High Safety Compliance, and Processing Efficiency must be achieved together. ULTEM™ LTX300A PEI Resin is also RoHS Compliant, supporting Environmentally Responsible Material Selection while delivering reliable Aerospace-Grade Performance.
