LFT-G® PA6 LGF60-NG06 | The Extreme Stiffness Upgrade for PA6 GF60

LFT-G® PA6-LGF60 - Metal Replacement NylonEngineers specify PA6 GF60 when they need plastic to perform like metal. However, standard short-fiber PA6 GF60 has a major limitation: it is dangerously brittle and prone to warping. LFT-G® PA6-LGF60-NG06 is the technological breakthrough that makes 60% glass fiber content viable for dynamic structures.

This Natural Grade (NG06) composite packs a massive 60% Long Glass Fiber reinforcement into a Polyamide 6 matrix. The skeletal network of long fibers solves the brittleness issue, providing a flexural modulus (stiffness) that rivals die-cast aluminum while retaining enough toughness to survive shock loads. It is the ultimate choice for replacing heavy steel or aluminum parts in automotive, railway, and heavy industrial machinery.

  • √ Aluminum-Like Stiffness: Delivers a flexural modulus approaching 19,000 MPa, allowing for extremely rigid parts with zero deflection under heavy loads.
  • √ Solves Creep & Fatigue: Unlike metals which can fatigue, and standard plastics which creep, LFT PA6 LGF60 maintains dimensions under permanent stress and vibration.
  • √ Excellent Surface finish: Our LFT process ensures resin fully wets the fibers, reducing the "floating fiber" roughness often seen in highly filled short-fiber compounds.

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) 260 - 290 °C
Mold Temperature (Zone ②) 80 - 110 °C
Back Pressure Low (to minimize fiber damage)

Extreme Load Zone Applications

🚈

Railway Fasteners

Critical infrastructure components. LFT PA6 LGF60 replaces cast iron, withstanding the immense compressive vibration of passing trains without creep or corrosion.

🏹

Archery Bow Risers

Requires extreme stiffness to prevent flexing during the draw cycle. The 60% fiber content provides the rigidity of aluminum but with superior vibration damping for a smoother shot.

⚙

High-Pressure Pump Heads

For industrial pressure washers. The burst strength of PA6 LGF60 is phenomenal, containing high-pressure water without the fatigue failure common in short-fiber parts.

People Also Ask (Google PAA)

1. Is Nylon 6 stronger than aluminum?

A: In terms of "Specific Strength" (strength-to-weight ratio), yes. While aluminum has a higher absolute modulus, LFT-G® PA6 LGF60 offers a structural performance that allows you to replace aluminum parts with a component that is 50% lighter, corrosion-proof, and cheaper to manufacture, without sacrificing load-bearing capacity.

2. What is the density of PA6 GF60?

A: The density of LFT-G® PA6 LGF60 is approximately 1.65 g/cm³. Compare this to aluminum (2.7 g/cm³) or steel (7.8 g/cm³). This significant density difference is the key driver for using high-glass-content nylon in lightweighting automotive and industrial applications.

3. Can you injection mold 60% glass fiber nylon?

A: Yes, but it requires LFT technology. Standard *short fiber* 60% compounds often have flow issues and result in poor surface finish ("floating fibers"). Our LFT-G® Long Fiber pellets are designed with excellent flow properties, allowing the high fiber content to be molded into complex shapes with a surprisingly good surface finish for such a rigid material.
