50% Long Glass Fiber Reinforced Nylon 66 Material
What is PA66 GF50?
PA66 GF50 is an ultra-high performance composite using a Polyamide 66 (Nylon 66) base reinforced with a 50% loading of glass fibers. LFT-G® technology enhances this by utilizing long glass fibers to create a robust internal fiber skeleton. This results in a material with exceptional strength and stiffness, making it a direct substitute for metals like aluminum, zinc, and magnesium.
This is our pinnacle strength compound, engineered for the most critical load-bearing applications. It combines the extreme mechanical properties of 50% LGF with the superior thermal and chemical resistance of PA66, creating the ultimate solution for replacing structural metal components.
LFT-G® PA66 GF50 enables direct metal replacement.

Frequently Asked Questions
Q: When is LFT PA66 LGF50 the definitive choice?
A: LFT PA66 LGF50 is the definitive choice when your application requires the absolute maximum strength and stiffness possible from our PA66 portfolio, especially in high-temperature conditions. It is specifically designed for direct replacement of structural metals where performance cannot be compromised.
Q: How does the 50% fiber loading impact processing and design?
A: The high fiber content results in a high-viscosity melt with lower flow. This necessitates robust processing equipment and carefully designed molds with generous flow paths and large gates. We strongly recommend a collaborative design and mold flow analysis phase to ensure success, a service our expert team provides.
