What is the Difference Between LFT-G^®PA12 GF40 and PA12 GF40?

LFT long fiber VS short fiber composite.jpg

LFT-G^®PA12 GF40 is our premium long-glass-fiber-reinforced Nylon 12,engineered to fundamentally outperform standard short-glass-fiber (GF) alternatives.

The critical difference lies in fiber length: our material preserves long, integral fibers that form a continuous reinforcement network, whereas short fibers in conventional PA12 GF40 provide only limited reinforcement. This structural superiority translates directly into exceptional impact resistance, superior toughness, and outstanding resistance to creep and fatigue. For applications demanding metal-like durability, high dynamic load endurance, and ultimate reliability, where standard materials reach their limits, LFT-G^®PA12 GF40 provides the definitive high-performance solution.

What is the Manufacturing Process of LFT-G^®PA12 GF40?

PA12 GF30 Manufacturing

Intro

LFT-G^® PA12 GF40 (40% Long Glass Fiber Reinforced PA12) pellets are made via a streamlined, high-precision process to ensure consistent fiber dispersion and mechanical strength. Here's our core production flow:

Step-by-Step Production

1. Fiber Roving Prep: Premium fiberglass rovings are unwound and aligned for uniform distribution, critical for maintaining 40% long glass fiber loading in PA12 LGF40.

2. Polymer Melting: Virgin PA12 resin and performance additives are melted in an extruder to create a homogeneous thermoplastic melt, optimized for fiber bonding.

3. Impregnation (Core Step): Fibers are saturated with molten PA6 in an advanced impregnation die, ensuring full coating and a precise 40% fiber-to-resin ratio for PA12 LGF40.

4. Pulling & Cooling: The composite strand is pulled to maintain tension, then cooled to solidify the matrix and preserve the 11mm fiber length that defines PA12 LGF40 performance.

5. Granulation: The solid strand is cut into 0.5" / 11mm PA12 LGF40 pellets, ready for downstream injection molding or extrusion.

What are the Key Applications of LFT-G^®PA12 GF40?

Automotive Oil Pans

In hybrid and electric vehicles, lightweight plastic oil pans increasingly rely on LFT-G^®PA12 GF40 for top performance. Boasting high stiffness, heat oil resistance, and robust impact strength, it replaces aluminum to cut weight and integrates complex baffles, elevating NVH and oil control efficiency.

Power Tool Housings

For professional-grade power tools like hammer drills and demolition breakers, LFT-G^®PA12 GF40 is the go-to for housings and motor shrouds. It withstands intense impacts and vibrations, delivering exceptional fatigue resistance and dimensional stability to outperform short-fiber materials and avoid component cracking.

Bicycle Crankset Arms

High-performance bicycle crankset arms for mountain and road bikes require a balance of light weight and strength-LFT-G^®PA12 GF40 meets this demand perfectly. It handles heavy cyclic pedaling loads even under high torque, offering safer performance than composites and better durability than traditional metal options.

FAQ

What is LFT-G^®PA12 GF40 material?

A: LFT-G^®PA12 GF40 refers to 40% long glass fiber reinforced PA12, a high-performance engineering plastic. It inherits the excellent heat and oil resistance of pure PA12, and gains enhanced stiffness, dimensional stability and fatigue resistance via long glass fiber reinforcement, making it ideal for high-load structural parts.

What is the difference between Nylon 12 and LFT-G^®PA12 GF40?

A: Pure Nylon 12 has good flexibility but low stiffness. LFT-G^®PA12 GF40 is 40% long glass fiber reinforced Nylon 12, with significantly enhanced stiffness, dimensional stability and fatigue resistance. It replaces pure PA12 in high-load applications (e.g., automotive oil pans) while retaining PA12's heat and oil resistance.

Is LFT-G^®PA12 GF40 suitable for new energy vehicles?

A: Yes, PA12 LGF40 is ideal for new energy vehicles. It is widely used in battery pack brackets and engine compartment structural parts, ensuring fire safety and structural stability while achieving lightweight to reduce vehicle load.
