LFT-G® ABS GF40 Long Glass Fiber Reinforced Pellets
Description
LFT-G® ABS GF40 is a high-performance engineering thermoplastic based on Acrylonitrile Butadiene Styrene (ABS) reinforced with 40% long glass fibers. This advanced grade utilizes long-fiber technology to deliver superior stiffness, impact strength, and dimensional stability, making it an ideal metal replacement solution for structural automotive components, industrial machinery parts, and demanding technical applications requiring enhanced mechanical performance and heat resistance.
Key Performance
- High Stiffness & Strength: 40% long glass fibers provide exceptional load-bearing capacity and structural rigidity.
- Superior Impact Performance: Long fiber network absorbs energy and resists crack propagation under stress.
- Excellent Dimensional Stability: Minimizes warpage and shrinkage, ensuring precision in complex geometries.
- Enhanced Heat Deflection Temperature: Maintains mechanical integrity under continuous thermal exposure.
- Ideal for Metal Replacement: Offers a lightweight solution with comparable strength and creep resistance.
- Good Surface Aesthetics: Delivers smooth, high-quality finish suitable for visible components.
Microstructure Characteristics
Engineered to outperform conventional reinforced plastics, LFT-G® ABS GF40 offers a significant upgrade in performance for technical components requiring maximum durability. The extended fiber length within the polymer matrix creates a dense network of reinforcement, providing a "metal-like" performance profile ideal for industrial and automotive applications.
📏 Resin length >6 mm
Unlike short-fiber compounds (1–3 mm), ABS LGF40 retains fiber length above 6 mm after injection. This creates an entangled 3D network that distributes stress far more effectively - crack propagation is arrested, not just deflected.
🧱 Skeletal Reinforcement
The long fibers form a "skeleton" that reduces anisotropic shrinkage. Warpage drops by 60% compared to short-fiber ABS LGF40. Parts behave more like isotropic materials, enabling tighter tolerances.
Processing Guidelines
To ensure optimal performance and minimize fiber breakage during the injection molding of LFT-G® PP- GF30, follow these recommended processing steps and parameters:
| Parameter | Recommended Range | Key Notes for PP LGF30 |
| Drying Temperature ① | 90 – 110 °C | Use a desiccant/dry air dryer to avoid hydrolysis |
| Drying Time ① | 3 – 4 hours | Ensure uniform moisture removal before processing |
| Melt Temperature (Nozzle) ③ | 210 – 240 °C | Avoid overheating to preserve fiber integrity |
| Mold Temperature ② | 40 – 60 °C | Balances flowability and part dimensional stability |
| Injection Speed | Slow to Moderate | Minimize fiber breakage and internal shear |
Critical Tips：
Screw: Low-compression screw to reduce fiber breakage
Gating: Generous gating for smooth material flow

The Challenge
A robotics manufacturer needed to reduce arm weight for faster motion cycles without sacrificing rigidity and precision. Traditional aluminum robot arms were overly heavy, leading to high energy consumption, limited operational speed, and reduced positional accuracy during high-speed movements. Additionally, the aluminum arms exhibited poor vibration damping, which compromised component handling precision and shortened the service life of associated mechanical parts.
The Solution
Switched to ABS LGF30 injection molding, leveraging 30% long glass fiber reinforcement to achieve an optimal balance of rigidity and lightweight performance. Optimized gate geometry and low-shear processing were implemented to preserve fiber length, ensuring uniform fiber distribution throughout the arm's complex structure. Internally designed complex rib structures further enhanced structural integrity, while precise mold temperature control improved dimensional stability and surface finish, eliminating the need for post-machining.
The Result
Weight reduction: 45% lighter than aluminum arms, effectively cutting energy consumption
Cycle efficiency: operation speed increased by 30%, improving overall production efficiency
Part cost: 40% lower manufacturing cost compared to traditional aluminum parts
Fatigue performance: excellent vibration damping and long-term fatigue resistance
Dimensional stability: precision molding realized with zero warpage for stable assembly
