Standard PA6 GF30 broadly defines a 30% short glass fiber-reinforced polyamide composite. Building upon this baseline, LFT-G® PA6 LGF30 (Polyamide 6 Long Glass Fiber 30%) is designed as a direct high-performance upgrade material that leverages a polyamide 6 matrix infused with 30% continuous long glass fibers through advanced pultrusion technology.
This unique structural network establishes an internal 3D fiber skeleton within the molded part, significantly enhancing impact resistance, creep tolerance, and high-temperature mechanical retention. It is the ultimate metal replacement solution for extreme automotive under-the-hood components, heavy-duty power tools, and industrial structural brackets requiring exceptional dynamic fatigue life.

Recommended Applications & Replacement Value
Adjacent Grade Comparison: PA6 LGF30 vs. PA6 GF30
Many design engineers default to standard short-fiber PA6 GF30, only to encounter field failures due to brittleness. Discover why upgrading to continuous long glass fiber (LGF) is essential for high-stress applications.
Standard PA6 GF30 (Short Fiber)
- Fiber Length: Usually < 1mm in the molded part.
- Impact Behavior: Brittle failure. Sudden cracks propagate easily through the resin.
- Fatigue Life: Low. Constant vibration breaks the weak fiber-resin bonds.
- Verdict: Suitable for basic rigidity, but unsafe for heavy-load dropping.
LFT-G® PA6 LGF30 (Long Fiber)
- Fiber Length: 5mm to 12mm continuous skeleton in the molded part.
- Impact Behavior: Ductile energy absorption. Fibers pull out, preventing shattering.
- Fatigue Life: Exceptional. The 3D fiber network anchors the polymer under cyclic stress.
- Verdict: The superior choice for structural integrity and metal replacement.
