LFT-G® PA6 GF30 (Model: LFT-PA6-GF30-NG03) is a premium engineering composite featuring a tough Polyamide 6 (Nylon 6) matrix reinforced with 30% continuous long glass fiber. Engineered for harsh thermal and mechanical environments, it effectively bridges the performance gap between standard plastics and light metals.
Core Capabilities:
● Thermal Endurance: High Heat Deflection Temp (HDT) up to 210°C.
● Dynamic Toughness: 3D fiber skeleton absorbs massive shock energy.
● Metal Replacement: Replaces aluminum in under-hood automotive parts.
● Dimensional Accuracy: Dramatically reduced shrinkage compared to unreinforced PA6.

Industry Applications: High Heat & High Stress
Automotive Under-Hood Components
Engine bay parts face constant extreme heat and chemical exposure. With an HDT of 210°C, LFT-G® PA6 LGF30 perfectly replaces aluminum in engine covers, air intake manifolds, and radiator end tanks, offering massive weight savings without thermal deformation.
Power Tool Gears & Housings
Industrial tools vibrate violently and run hot. The Polyamide 6 matrix provides excellent wear resistance and heat tolerance, while the 30% long fiber skeleton absorbs high-frequency vibrations, preventing the casing or internal gears from fatigue fracturing.
Industrial Machinery Pulleys
Replaces heavy die-cast zinc and steel in pulleys and load-bearing brackets. The material significantly reduces rotational mass, improving energy efficiency, while maintaining the tensile strength necessary to handle heavy belt loads continuously.
Frequently Asked Questions (FAQ)
Q: How does moisture absorption affect PA6 LGF30?
A: Polyamide 6 (Nylon) naturally absorbs moisture, which generally increases its toughness but slightly lowers its stiffness. However, because our material is locked together by a rigid 30% long glass fiber skeleton, the dimensional changes and modulus loss due to moisture are dramatically reduced compared to unreinforced PA6.
Q: Why choose Long Fiber PA6 over Short Fiber PA6?
A: Standard short fiber PA6 is highly susceptible to creep (deformation over time) and fatigue failure. LFT-G® preserves 10-12mm continuous fibers. This creates an internal 3D mesh that boosts impact strength, doubles fatigue endurance, and minimizes long-term creep under load.
Q: Is PA6 GF30 a viable metal replacement?
A: Yes. With a tensile strength exceeding 150 MPa and an HDT of 210°C, it routinely replaces aluminum and magnesium in under-hood automotive brackets, cutting part weight by up to 50% while eliminating costly secondary CNC machining.
