It stands as the ultimate thermoplastic solution for advanced automotive under-hood components, next-generation EV battery housings, and high-performance industrial equipment. In short, this page details an engineering solution for superior high-temperature performance, ultimate lightweighting, and structural integrity (LFT-G® PA66 CF50-BC05B) - blending the peak structural power of 50% long carbon fiber with the excellent thermal resistance of a Nylon 66 matrix, ideal for next-generation automotive under-hood parts, EV battery enclosures, and high-end industrial devices.
Q: What is carbon fiber nylon 66 used for?
A: It's ideal for structural components exposed to high temperatures, such as automotive under-hood parts, industrial pump housings, and advanced drone structures. The Nylon 66 base provides superior thermal stability while carbon fiber reinforcement offers extreme stiffness and strength.
Q: How does PA66 CF50 differ from PA6 CF50?
A: Both are excellent high-performance carbon fiber nylon composites. However, Nylon 66 (PA66) offers higher heat deflection temperature (HDT) and generally better long-term thermal stability compared to Nylon 6 (PA6). This makes PA66-CF50 the preferred choice for applications requiring sustained performance at elevated temperatures.
Q: Can carbon fiber nylon 66 withstand high temperatures?
A: Absolutely. With a Heat Deflection Temperature (HDT) of over 250°C (at 1.8 MPa), LFT-G® PA66-CF50 maintains its structural integrity and mechanical properties at temperatures far exceeding those where standard engineering plastics fail. It's designed for continuous use in harsh thermal environments.

Case Study: EV Battery Module Housing
The Challenge
A major electric vehicle manufacturer sought to develop a lighter, safer, and more cost-effective housing for their new high-density battery modules. The housing needed to be extremely rigid to protect the cells from impact and vibration, dissipate heat effectively, and crucially, maintain structural integrity during thermal runaway events. Traditional metal housings were heavy, expensive, and offered limited design flexibility for integrated cooling channels.
The Solution: LFT-G® PA66-CF50
Our LFT-G® PA66-CF50 was selected as the optimal material. Its 50% long carbon fiber reinforcement provided the exceptional stiffness and strength required for robust structural protection and crush resistance. The inherent high-temperature resistance of the PA66 matrix ensured integrity even under extreme thermal loads. By using injection molding, complex geometries with integrated mounting points and internal cooling ribs were achieved in a single, lightweight part, significantly improving thermal management and reducing assembly complexity.
Result: A 35% lighter battery module housing with superior thermal and impact resistance, allowing for higher energy density and a 25% reduction in overall manufacturing cost.
