LFT-G® PA66 HLGF40-FR | The High-Strength V-0 Upgrade for PA66 GF40
LFT-G® 40% Long glass fiber PA66 (High Performance FR)
Standard PA66 GF40 offers exceptional strength but burns easily. Standard Flame Retardant (FR) nylons are safe but often brittle and weak due to additives. LFT-G® PA66-HLGF40FR breaks this trade-off.
This "High Performance" (HLGF) grade is an engineering marvel. It integrates 40% Long Glass Fibers with a specialized V-0 flame retardant system into a heat-resistant PA66 matrix. By using advanced coupling technology, we recover the mechanical strength usually lost in FR grades, offering properties 10-15% higher than competitors. It is the ultimate solution for structural parts that sit near high voltage or heat sources.
- √ UL94 V-0 Safety: Self-extinguishes within 10 seconds, preventing fire spread in EVs and industrial electronics.
- √ Retained Structural Strength: Unlike typical FR nylons, this grade maintains high tensile strength (>180 MPa) and impact resistance thanks to the long fiber skeleton.
- √ High Heat Stability: The PA66 base resists short-term spikes up to 250°C, making it ideal for connectors and housings next to hot engines or busbars.

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) |
