Key Questions Answered:
What is PA66 GF40?
It is a strong and stiff engineering composite. Our long-fiber FR (flame resistance) grade enhances this by adding certified V-0 fire safety, making it ideal for high-performance auto parts.
Why is V-0 Flame Resistance important?
A V-0 rating is critical for safety in electronic and automotive applications. It ensures the material will quickly self-extinguish if ignited, preventing the spread of fire and protecting valuable components and, most importantly, lives.

Case Study: Automotive ECU Housing
The Challenge
An automotive electronics supplier was developing a new Engine Control Unit (ECU) to be mounted directly on the engine block. The housing needed to be a structural component, protecting sensitive electronics from extreme vibration and potential impacts. The key challenges were twofold: the material needed to withstand continuous high temperatures and have a UL94 V-0 rating for fire safety, while also being strong enough to replace the previous cast aluminum design to save weight and cost.
The Solution: LFT-PA66-HLGF40FR
Our material provided a perfectly balanced solution. Its 40% long fiber reinforcement delivered the stiffness and strength required to pass all vibration and drop tests. Simultaneously, the V-0 FR system ensured compliance with automotive fire safety standards. We collaborated with the client on part design, optimizing wall thickness and rib placement to ensure EMI shielding could be effectively integrated, creating a robust, safe, and lightweight final part.
Result: A 40% lighter ECU housing that passed all thermal and safety validations, with a 15% reduction in total part cost compared to the aluminum alternative.
