LFT-G® PA6 LGF40-TA | The High-Impact Toughened Upgrade for PA6 GF40
LFT-G® 40% Long glass fiber PA6 (Toughened)
Standard PA6 GF40 is incredibly stiff, but stiffness often comes at a price: Brittleness. For parts subjected to drops, crashes, or extreme cold, standard glass-filled nylon can shatter like ceramic. LFT-G® PA6-LGF40TA (Toughened Grade) is the engineered solution to this critical failure mode.
This high-performance composite infuses a 40% Long Glass Fiber skeleton into a chemically Impact-Modified (Toughened) Polyamide 6 matrix. The result is a material that retains high structural strength but gains the ability to absorb massive amounts of kinetic energy. It transforms "brittle failure" into "ductile yielding," making it the safest choice for power tools, sports equipment, and automotive crash components.
√ Extreme Impact Strength: The toughened matrix allows the material to flex slightly under shock loads, preventing cracks from propagating, even at -30°C.
√ Reduced Notch Sensitivity: Unlike standard PA6 GF40, this TA grade is forgiving of design features like sharp corners or holes that usually act as stress concentrators.
√ Fatigue Durability: Combines the endurance of long fibers with the resilience of elastomers to withstand millions of high-stress vibration cycles.
The Impact Shield: How TA Works
Under a heavy hammer blow, standard plastic shatters. LFT-G® PA6-LGF40TA absorbs the blow.
Standard PA6 GF40
💥
Brittle Fracture
Energy cannot dissipate. The molecular chains snap immediately upon impact.

🛡️
Energy Absorption
Elastomer particles act as "shock absorbers," dispersing energy while long fibers hold the part together.
Typical Material Properties (Toughened)
The following values are typical data for LFT-G® PA6-LGF40TA (Toughened Grade) and are for reference only. Data is for Dry-As-Molded (DAM) state. Please contact us for the official Technical Data Sheet (TDS).
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.

Case Study: Heavy-Duty Rotary Hammer Housing
A professional power tool casing that must protect the motor and gearbox from job-site abuse.
The 6ft Drop Test Protocol
Standard PA6 GF40: FAIL Housing shattered upon impact at -10°C. The material was too brittle to absorb the shock energy.
Standard PC/ABS: MARGINAL Passed the drop test, but failed the heat test (warped next to the hot motor).
LFT-G® LGF40-TA: PASSED
Survived 20 drops from 2 meters at -20°C.
Maintained motor alignment under high heat.
Zero cracking due to toughened matrix.
Durability Map: Toughened Applications
🏒
Ice Hockey Blade Holders
Extreme cold + high velocity impact. LGF40-TA remains ductile on the ice, preventing the holder from snapping when hit by a puck or stick.
🚗
Automotive Crash Pads
Used in door panels and bumpers. The material absorbs kinetic energy during a collision, protecting passengers and reducing brittle fragmentation.
🚈
Railway Insulation Plates
Sits between the rail and sleeper. Withstands the massive, repetitive impact of train wheels without cracking, even in freezing winter conditions.
People Also Ask (Google PAA)
1. How to improve the impact strength of PA6?
A: Impact strength is improved by adding an elastomer (rubber) modifier to the Polyamide 6 matrix. This "Toughened" (TA) modification allows the plastic to deform slightly and absorb energy instead of breaking. LFT-G® PA6 LGF40-TA combines this toughening with long glass fibers for the best of both worlds: stiffness and durability.
2. Does Nylon get brittle in cold weather?
A: Yes, standard dry Nylon 6 can become brittle below freezing. However, Toughened grades like LFT-G® LGF40-TA are specifically engineered to remain ductile at temperatures as low as -30°C or -40°C, making them essential for winter sports equipment and automotive exterior parts in cold climates.
3. What is the difference between PA6 GF30 and PA6 GF40 in impact?
A: Typically, adding more glass fiber (going from 30% to 40%) makes the material stiffer but *more brittle*. However, with our LFT Toughened Grade (TA), we counteract this brittleness. LFT-G® PA6 LGF40-TA offers higher impact strength than even a standard GF30, despite having more glass, due to the long fiber length and impact modifiers.
