LFT-G® PA6 HLGF30 | The High-Performance PA6 GF30 (15% Stronger)
LFT-G® 30% Long glass fiber PA6 (High Performance)
For 90% of applications, standard PA6 GF30 is sufficient. But for the critical 10%-where safety factors are tight and loads are extreme-standard grades fail. LFT-G® PA6-HLGF30 (High Performance Grade) is engineered for that top tier.
Through advanced resin coupling technology and optimized fiber impregnation, this grade achieves 10-15% higher mechanical properties than our natural grade. It pushes the limits of what a 30% glass fiber Polyamide 6 composite can do, offering elite-level tensile strength and fatigue resistance for automotive safety parts and heavy industrial machinery.
√ Boosted Mechanicals: Enhanced fiber-to-resin bonding results in tensile strength exceeding 200 MPa, significantly outperforming standard PA6 GF30.
√ Extreme Fatigue Endurance: The stronger interface delays crack initiation, extending the lifespan of parts under dynamic cyclic loading.
√ Premium Surface Appearance: Improved fiber dispersion results in a smoother, more uniform surface finish, suitable for visible structural components.
The "High Performance" Difference
Why upgrade to HLGF30? The data speaks for itself. We've optimized the matrix to squeeze every bit of performance out of the glass fibers.
Tensile Strength +15% vs. Standard PA6 30LGF
Impact Strength +12% vs. Standard 30%LGF PA6
Fatigue Life Extended Superior Durability
Typical Material Properties (High Performance)
The following values are typical data for LFT-G® PA6-HLGF30 (High Performance Grade) and are for reference only. Data is for Dry-As-Molded (DAM) state. Please contact us for the official Technical Data Sheet (TDS).
The following values are recommendations. We recommend desiccant / dry air dryers (moisture content below 0.1%).
To minimize fiber breakage and ensure optimal performance, a low-compression, general-purpose screw is highly recommended.

Case Study: Automotive Roof Rack Support
A critical safety part that bears the dynamic load of luggage boxes and bikes at highway speeds (wind drag + weight).
The Breaking Point
Standard PA6 GF30 supports were failing the "200kg Dynamic Load Test." Micro-cracks formed at the bolt holes under cyclic vibration, leading to potential detachment risks.
The High-Performance Fix
Switching to LFT-G® PA6-HLGF30 increased tensile strength to 210 MPa. The improved fiber bonding prevented micro-cracking. The part passed the 200kg test with a 3x safety factor margin.
Applications for Engineering Challenges
Robotic Joints
Requires zero backlash and high fatigue life. HLGF30 offers the precision and wear resistance needed for industrial robot arms, outlasting standard nylon.
Heavy Circuit Breakers
Structural housings for high-voltage breakers. The enhanced mechanicals ensure the housing doesn't flex during the violent "snap" of a trip event, ensuring arc extinction.
High-Torque Gears
For power transmission. The 15% extra strength translates directly into higher torque capacity and tooth shear resistance compared to standard glass-filled nylon.
People Also Ask
1. What is the strongest grade of PA6?
A: "High Performance" Long Fiber Reinforced (LFT) grades, like LFT-G® HLGF30, are among the strongest. By optimizing the fiber-resin bond and maintaining fiber length, they achieve tensile strengths over 200 MPa, significantly higher than standard short-fiber PA6 compounds.
2. Does glass fiber reinforcement affect moisture absorption in Nylon 6?
A: Yes, it reduces it. While the Nylon matrix still absorbs moisture, the glass fibers do not. In a 30% glass filled grade, there is 30% less nylon to absorb water, and the glass skeleton physically restrains swelling, making LFT PA6 GF30 much more dimensionally stable than unfilled nylon.
3. What is the difference between standard and high-performance polyamide?
A: The difference lies in the additives and manufacturing process. High Performance grades (like our HLGF series) use superior coupling agents to bond the plastic to the glass more tightly. This results in higher tensile strength (+15%), better fatigue life, and improved resistance to hydrolysis compared to standard commodity grades.
