Chemical Resistance (Typical for Aerospace Applications)
LFT-G® PA6 CF40 exhibits good to excellent resistance to various substances encountered in aerospace environments. Resistance can vary with specific fluid composition, concentration, temperature, and exposure time. Always test for specific application conditions and verify compatibility with relevant aerospace specifications.

- Jet Fuel (e.g., Jet A-1, JP-8) - Excellent
- De-icing Fluids (e.g., Propylene/Ethylene Glycol based, AMS 1424/1428) - Good
- Aircraft Cleaning Agents (approved, neutral pH) - Good
- Lubricating Oils and Greases (mineral and synthetic aviation grade) - Excellent
- Water and Humidity - Fair to Good (Note: PA6 is hygroscopic; dimensional changes and variations in mechanical properties due to moisture absorption must be accounted for in design. Pre-conditioning or specific grades may be necessary for critical applications.)
Processing Information (Typical for Aerospace Components)
Recommended processing conditions for LFT-G® PA6 CF40 for injection molding of Aerospace Overhead Bin Support Bracket:

Notes and Supplementary Information for Aerospace Applications:
Data Source and Applicability: This data is compiled based on typical values for PA6 CF40 from international material manufacturers and standards, oriented towards demanding aerospace applications. Key characteristics such as exceptional creep resistance, fatigue strength, and dimensional stability are highlighted. LFT-G® PA6 CF40 is specifically engineered for components like Aerospace Overhead Bin Support Brackets, offering a critical combination of high strength-to-weight ratio, superior stiffness, and robust long-term performance. These attributes, coupled with significant lightweighting benefits, make it an ideal candidate for safety-critical structural parts in aircraft interiors.
Critical Considerations for Aerospace Use:
- Moisture Management: Proper drying before processing is paramount. The hygroscopic nature of PA6 means that moisture absorption can affect dimensional stability and mechanical properties; this must be accounted for in design and potentially mitigated through conditioning or specialized grades. Detailed analysis of in-service environmental conditions is recommended.
- Flammability, Smoke, Toxicity (FST): While base PA6 CF40 can achieve UL94 V-0, specific formulations of LFT-G® PA6 CF40 are generally required to meet stringent aerospace FST standards such as FAR 25.853, Airbus ABD0031, or Boeing BSS 7239. Always verify FST compliance documentation for the specific grade used from the material supplier.
- Electrical Conductivity: The inherent electrical conductivity of carbon fiber reinforcement must be considered in the design to prevent ElectroMagnetic Interference (EMI) or Radio Frequency Interference (RFI) issues, ensure proper grounding if required, or manage electrostatic discharge (ESD) concerns.
- Regulatory Compliance & Traceability: Adherence to all relevant aerospace material specifications (e.g., AMS, company-specific procurement specifications) and airworthiness regulations is mandatory. Full material traceability is typically required.
- Outgassing: For components used within pressurized cabins or in vacuum environments (e.g., spacecraft), outgassing properties (ASTM E595) might need to be considered and tested.
For precise and certified data for your specific aerospace program, including long-term performance under operational conditions (e.g., thermal cycling, vibration, fluid exposure), always consult the official material certificate of conformity and project-specific documentation provided by the qualified LFT-G® material supplier.
