LFT-G® PA66 HLGF50-FR | The High-Strength V-0 Upgrade for PA66 GF50
LFT-G® 50% Long glass fiber PA66 (High Performance FR)
Standard PA66 GF50 offers incredible stiffness but is highly flammable. Traditional Flame Retardant (FR) nylons are safe but often suffer a 30-40% drop in strength due to additives. LFT-G® PA66-HLGF50FR solves this engineering paradox.
This "Elite" grade integrates a massive 50% Long Glass Fiber skeleton with a specialized V-0 flame retardant system into a heat-resistant PA66 matrix. By using our proprietary High Performance (HLGF) coupling technology, we recover the mechanical strength usually lost in FR grades. It delivers properties 10-15% higher than standard FR composites, making it the ultimate choice for high-voltage EV components and industrial switchgear that demand both metal-like rigidity and fire safety.
- √ UL94 V-0 Certified: Rapidly self-extinguishes and prevents flaming drips, essential for preventing thermal runaway propagation in battery systems.
- √ Extreme Stiffness (>12 GPa): Despite the FR additives, the 50% long fibers maintain a flexural modulus rivaling aluminum, ensuring zero deformation under load.
- √ High Heat Stability: The PA66 base allows for short-term exposure up to 250°C, perfect for connectors near hot busbars or engines.

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) | 270 - 300 °C |
| Mold Temperature (Zone ②) | 80 - 110 °C |
| Back Pressure | Low (to minimize fiber damage) |
