This is our apex material, engineered for applications where both ultimate structural performance and uncompromising fire safety are non-negotiable. It combines an extremely high 50% long glass fiber loading with a high-performance, UL94 V-0 certified flame retardant system. In short, this page details an uncompromised engineering solution (LFT-G®PA66-HLGF50FR) - blending the peak structural performance of 50% long fiber with UL94 V-0 fire safety for the most demanding automotive and industrial applications.
Key Questions Answered:
What is PA66 GF50?
It's an ultra-stiff composite for metal replacement. Our long-fiber FR grade enhances this with superior toughness and certified fire safety for critical auto parts.
What does UL94 V-0 mean?
It is the highest rating for flame retardancy in plastics under UL94. It means the material self-extinguishes within 10 seconds on a vertical specimen, with no flaming drips allowed, making it ideal for safety-critical applications like EV batteries.
Performance Without Compromise: A Dual-Axis Comparison
Axis 1: Structural Performance (Strength & Stiffness)
Axis 2: Fire Safety (Flame Retardancy)
Conclusion: Only LFT-PA66-HLGF50FR delivers both elite structural performance and the highest level of fire safety, eliminating the need for engineering compromises.
Case Study: Electric Vehicle (EV) Battery Pack Enclosure
The Challenge
A leading EV manufacturer needed a material for their next-generation battery pack enclosure. The requirements were exceptionally demanding: it needed to provide robust structural protection for the battery cells in a crash scenario (replacing aluminum), while also guaranteeing UL94 V-0 flame retardancy to prevent thermal runaway events. Furthermore, the material had to be lightweight and suitable for complex, high-volume injection molding.
The Solution: LFT-PA66-HLGF50FR
Our material was the only solution that met all criteria. Its 50% long fiber content provided the metal-like stiffness and impact strength required for structural protection, while the integrated V-0 FR system ensured the highest level of fire safety. We worked with the OEM's engineers to run extensive FEA and mold-flow simulations, ensuring the final part design was optimized for safety, weight, and manufacturability.
Result: A lighter, safer, and more cost-effective battery enclosure that passed all OEM crash and thermal validation tests.
