LFT‑G® PA6‑LGF50 | 50% Long Glass Fiber Reinforced Nylon 6
What is PA6‑LGF50?
LFT‑G® PA6‑LGF50 is a high‑performance engineering thermoplastic composed of Nylon 6 (PA6) reinforced with 50% long glass fibers (LGF). Designed for demanding structural applications, this long‑fiber reinforced compound delivers exceptional tensile strength, flexural modulus, and impact resistance – significantly outperforming standard short‑glass PA6 grades. The continuous long‑fiber network forms a 3D reinforcement architecture within molded parts, providing superior creep resistance, dimensional stability, and thermal performance for metal‑replacement solutions in automotive, industrial, and electrical applications.
Key Performance Advantages
Ultra‑High Tensile & Flexural Strength
50% long glass fiber reinforcement delivers high tensile strength and excellent flexural modulus – a 60%+ improvement over standard PA6 GF30. Ideal for load‑bearing structural components requiring metal‑like rigidity.
Outstanding Impact Toughness
Notched Izod impact strength is nearly double that of short‑fiber PA6 GF50. The continuous long‑fiber network absorbs impact energy more effectively, reducing part fracture risk in high‑vibration environments.
High‑Temperature Performance & Creep Resistance
Heat deflection temperature far exceeds standard PA6. The long‑fiber network minimizes creep under sustained load, ensuring dimensional accuracy in high‑heat, long‑term service conditions.
Process‑Friendly & Cost‑Effective
Compatible with standard injection molding equipment. Optimized melt flow and low warpage reduce scrap rates and secondary finishing – lowering total part cost in high‑volume production.

FAQ
Q: What makes PA6‑LGF50 different from standard PA6 GF50?
A: The key difference lies in fiber length. PA6‑LGF50 uses long glass fibers (LGF) that remain continuous within the pellet and form an interconnected 3D network in molded parts. This delivers significantly higher impact strength (43 vs. ~22 kJ/m²), better creep resistance, and superior dimensional stability compared to short‑fiber GF50 grades – all at the same 50% glass loading.
Q: Can PA6‑LGF50 be used in high‑temperature environments?
A: Absolutely. With a heat deflection temperature of 256°C at 1.8 MPa, PA6‑LGF50 far exceeds standard PA6 grades (typically 180‑200°C). It is well‑suited for under‑hood automotive components, industrial machinery exposed to heat, and electronic assemblies requiring soldering resistance.
Q: What processing equipment is required for PA6‑LGF50?
A: Standard injection molding machines with a low‑compression screw and free‑flow check valve are recommended. Drying at 85‑110°C for 3‑5 hours is essential to reduce moisture below 0.05%. Melt temperature should be maintained at 267‑299°C to prevent degradation.
