LFT-G® PA6 HLGF50 | The Ultimate High-Modulus Upgrade for PA6 GF50

LFT-G® 50% Long glass fiber PA6 (High Performance)

LFT-G® PA6-HLGF50 - Ultimate Stiffness Nylon When standard PA6 GF50 reaches its breaking point, LFT-G^® PA6-HLGF50 takes over. Standard short-fiber 50% glass nylon is strong, but it is brittle and prone to fatigue. Our "High Performance" (HLGF) series is engineered for applications where even standard long-fiber materials aren't enough.

This elite grade utilizes a proprietary coupling technology to maximize the bond between the Polyamide 6 matrix and the massive 50% Long Glass Fiber skeleton. The result is a composite with mechanical properties 10-15% higher than our natural grade, offering a flexural modulus that rivals aluminum while cutting weight by half. It is the definitive material for replacing heavy metal castings in safety-critical railway, automotive, and industrial systems.

√ Ultimate Stiffness (+15%): Optimized interface bonding pushes the flexural modulus beyond 17,000 MPa, ensuring zero deflection under massive loads.
√ Extreme Burst Strength: Ideal for pressure vessels and valve bodies where standard PA6 GF50 would crack under internal pressure.
√ Superior Surface Finish: Advanced impregnation technology ensures fibers are fully wetted, reducing surface roughness common in high-glass content materials.

The Hierarchy of Stiffness

LFT-G® HLGF50 sits at the very top of the polymer performance pyramid, bridging the gap to structural metals.

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)	240 - 280 °C
Mold Temperature (Zone ②)	80 - 110 °C
Back Pressure	Low (to minimize fiber damage)

Injection molding Process info

Case Study: Heavy Truck Air Brake Valve

Complex high-pressure air brake valve body for trucks

A critical safety component handling 12-bar air pressure. Failure means loss of braking power.

Option A: Die-Cast Aluminum (Failed)

Too heavy, required expensive machining for seals, and suffered from corrosion in winter conditions.

Option B: Standard LGF50 (Marginal)

Met initial burst pressure but failed fatigue testing after 100,000 cycles due to fiber pull-out.

Option C: LFT-G^® HLGF50 (Winner)

+15% Strength made the difference. The enhanced bonding prevented fiber pull-out. Passed 1 million cycles and 20-bar burst test.

Industrial Titans: Extreme Applications

Crane Sheaves

Replaces steel pulleys. The extreme compressive strength of HLGF50 withstands heavy cable loads while reducing weight at the boom tip, improving crane stability.

Rail Insulator Blocks

Used in high-speed rail tracks. The material must isolate electricity while bearing the immense dynamic load of passing trains without crushing or creeping.

Hydraulic Manifolds

For medium-pressure hydraulic systems. The high burst strength and fatigue resistance of HLGF50 allows for complex, leak-proof fluid pathways that replace machined aluminum.
