LFT-G® PA6 HLGF40 | The Ultra-High Strength PA6 GF40 Upgrade

LFT-G® 40% Long glass fiber PA6 (High Performance)

LFT-G® PA6-HLGF40 - Ultra High Strength Nylon Standard PA6 GF40 is a robust material, but in extreme structural applications, "standard" isn't enough. When safety factors are slim and loads are critical, you need the Elite Grade. LFT-G^® PA6-HLGF40 (High Performance) is engineered to exceed the limits of conventional composites.

This specialized grade utilizes advanced coupling technology and optimized fiber impregnation to achieve mechanical properties 10-15% higher than our natural grade (NG04). With a tensile strength surpassing 230 MPa and extreme fatigue endurance, it is the ultimate replacement for die-cast metals in heavy-duty automotive, railway, and industrial machinery components where failure is not an option.

√ +15% Tensile Strength: Optimized fiber-to-resin bonding pushes strength levels beyond standard LFT, allowing for thinner walls or higher load capacities.
√ Extreme Stiffness: A flexural modulus of ~13.5 GPa provides rock-solid dimensional stability, minimizing deflection under heavy static loads.
√ Enhanced Fatigue Life: The stronger interface delays micro-crack formation, significantly extending the part's life under cyclic vibration and stress.

The High-Performance Delta (+15%)

Why choose HLGF40? Because in structural engineering, that extra 15% is the difference between safety and failure.

Tensile Strength

~~180 MPa~~ → 210 MPa

+16.5% Boost

Flexural Modulus

~~9.8 GPa~~ → 11 GPa

+12.5% Boost
