LFT-G® PA66 HLGF30 | High-Performance PA66 GF30 (+15% Strength)
LFT-G® 30% Long glass fiber PA66 (High Performance)
Standard PA66 GF30 is the workhorse of the automotive industry. However, when parts fail at the weld line or under peak loads, simply adding more glass isn't always the answer-you need better bonding. LFT-G® PA66-HLGF30 is the "Elite" upgrade to standard nylon composites.
This High Performance (HLGF) grade features 30% Long Glass Fiber reinforcement with a chemically optimized interface. By maximizing the adhesion between the PA66 matrix and the glass skeleton, we achieve mechanical properties 10-15% higher than our natural grade. It offers superior burst pressure resistance and fatigue life, making it the critical safety margin for engine cooling and oil systems.
- √ +15% Strength Boost: Optimized coupling agents increase tensile strength to >190 MPa, preventing failure in high-stress areas like bolt bosses.
- √ Superior Weld Line Strength: The long fibers bridge knit lines more effectively during molding, reducing the risk of bursting in pressurized housings.
- √ High-Heat Endurance: Retains structural stiffness closer to the melting point (262°C) than standard grades, ensuring stability in hot oil or coolant.

Processing Information
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.
| Parameter | Recommendation |
|---|---|
| Drying Temperature | 80 - 100 °C |
| Drying Time | 4 - 6 hours |
| Melt Temperature (Nozzle ③) | 280 - 300 °C |
| Mold Temperature (Zone ②) | 80 - 110 °C |
| Back Pressure | Low (to minimize fiber damage) |
