Material Overview
LFT‑G® PA66 LGF30 – High‑Load Thermal Structural Reinforced Composite
LFT‑G® PA66 LGF30 is a long‑glass‑fiber reinforced polyamide 66 compound designed for injection‑molded parts that demand high stiffness, creep resistance, and impact strength under continuous heat and stress. By combining a heat‑stabilized PA66 matrix with a continuous long‑fiber network, this material delivers outstanding high‑temperature performance and structural reliability - ideal for under‑hood automotive applications, power tool housings, and industrial components.
Through an advanced pultrusion process, LFT‑G® PA66 LGF30 preserves long fiber lengths inside each pellet, creating a three‑dimensional reinforcing skeleton. This architecture dramatically improves tensile strength, flexural modulus, and notched impact resistance, while suppressing creep even at elevated temperatures.
Supplied as ready‑to‑mold cylindrical pellets, LFT‑G® PA66 LGF30 runs on standard reciprocating‑screw injection molding machines. Low and isotropic shrinkage ensures tight tolerances and minimal warpage, while the PA66 matrix offers excellent resistance to oils, fuels, and solvents.
Core Strengths
Outstanding Heat Resistance & Thermal Durability
LFT‑G® PA66 LGF30 delivers exceptional thermal endurance tailored for high-heat operational scenarios. It maintains stable mechanical performance under sustained high temperatures and frequent temperature cycling, preventing softening or performance degradation in heat-intensive parts for automotive, electrical, and general industrial applications.
Strong Chemical & Fluid Compatibility
Backed by premium PA66 base resin and integrated long glass fiber framework, this compound offers excellent resistance to lubricants, fuels, and various industrial chemicals. It avoids swelling, corrosion, and structural damage after long-term contact with fluids, keeping components reliable in chemically harsh working environments.
Excellent Wear & Anti-Friction Performance
The reinforced long-fiber structure optimizes friction properties and greatly reduces material abrasion during mechanical movement. It maintains steady friction coefficients for a long service cycle, making it an ideal pick for moving parts, transmission units, and articulated components that demand durable anti-wear capability.
Great Toughness & Impact Endurance
Balancing rigidity and flexibility perfectly, LFT‑G® PA66 LGF30 withstands sudden impacts, collisions, and mechanical jolts without easy cracking or breakage. Its well-rounded toughness adapts to complex on-site operating conditions, lowering product failure risks and helping manufacturers create more robust end products.
Performance Comparison
LFT-G® PA66 LGF30 vs. PA66 GF30
Each card below highlights a critical performance metric. The multiplier shows how many times PA66 LGF outperforms PA66 SGF - a direct measure of the long‑fiber advantage.
Across every critical metric, LFT‑G® PA66 LGF30 delivers superior impact toughness, creep resistance, fatigue life, and dimensional stability compared to standard short‑glass‑fiber PA66. The continuous long‑fiber architecture is the single biggest factor driving this advantage – enabling stress transfer, crack bridging, and long‑term reliability that short fibers simply cannot match.

FAQ
Q: What makes LFT-G® PA66 LGF30 stronger than standard PA66 GF30?
A: Long glass fibers create a continuous 3D reinforcing network inside each pellet, which dramatically improves how the material absorbs impact and resists creep. Compared to standard short-fiber PA66 GF30, LFT-G® PA66 LGF30 delivers 2.6× higher notched impact strength and more than 4× better creep resistance - without sacrificing stiffness or heat performance.
Q: Can LFT-G® PA66 LGF30 replace metal in under-hood applications?
A: Yes. With excellent heat deflection temperature (>250°C) and outstanding resistance to oils, coolants, and vibration, PA66 LGF30 is a proven metal replacement for engine covers, cooling brackets, fan shrouds, and oil pans. It is 20–40% lighter than aluminum, reduces system weight, lowers emissions, and simplifies assembly while maintaining structural integrity under continuous thermal and mechanical loads.
Q: What molding conditions are needed for LFT-G® PA66 LGF30?
A: LFT-G® PA66 LGF30 runs on standard reciprocating-screw injection molding machines. Recommended melt temperature is 280–310°C, and pre-drying at 120°C for 4–6 hours is required to prevent moisture-induced degradation. The material exhibits low and isotropic shrinkage, which minimizes warpage and allows tight-tolerance molding even for complex part geometries.
