LFT-G® ABS LGF20 | Acrylonitrile Butadiene Styrene
Balanced Stiffness-Toughness Surface-Grade Long Glass Fiber Reinforced Thermoplastic
LFT-G® ABS LGF20 is a premium long glass fiber reinforced ABS compound, engineered to deliver an optimal balance of structural rigidity, impact toughness, and cosmetic-grade surface finish, while retaining the signature processability and aesthetic versatility of ABS resin.
Featuring a 20% continuous long-glass-fiber reinforcement system, this material delivers measurable upgrades in mechanical strength, creep resistance and dimensional accuracy over neat ABS, without sacrificing surface quality or melt flowability. It maintains reliable impact performance at both room and sub-ambient temperatures, exhibits minimal fiber bloom after molding, and supports secondary processes such as painting, electroplating, and silk-screening. With superior fluidity compared to higher glass-filled grades, it excels at thin-wall, complex-geometric parts that require both structural reliability and premium appearance. It is a cost-effective, lightweight solution for consumer electronics enclosures, automotive interior components, small appliance housings, and industrial parts that demand balanced performance, tight tolerances, and aesthetic quality.
Key Material Strengths
- Balanced Stiffness & Impact Toughness
Long glass fiber elevates flexural modulus and structural rigidity, while preserving the inherent high-impact performance of the ABS matrix; it delivers reliable toughness even at low temperatures.
- Cosmetic-Grade Surface Finish
Optimized compounding ensures uniform fiber dispersion with minimal surface fiber bloom, producing a smooth glossy finish directly out of the mold, ideal for visible exterior parts.
- Precision Dimensional Stability
3D long-fiber network reduces molding shrinkage and thermal warpage, maintaining tight dimensional tolerances across temperature fluctuations for precision assembly.
- Excellent Flow & Process Flexibility
Superior melt flow versus higher fiber-filled grades, enabling easy molding of thin-wall sections and intricate geometries on standard injection equipment.
- Versatile Finishing Compatibility
Supports painting, electroplating and hot stamping with strong coating adhesion; can be formulated for enhanced UV resistance for outdoor deployment.
Test Data Comparison
20% Glass Reinforced ABS: Long Fiber vs. Short Fiber
The chart above compares LFT‑G® ABS LGF20 (20% long glass fiber reinforced ABS) with a standard short glass fiber ABS GF20. Across five core engineering metrics - notched impact toughness, surface finish quality, dimensional accuracy, long‑term creep resistance and cyclic fatigue durability - the long‑glass formulation consistently delivers superior overall performance.
The continuous long fiber architecture forms an interconnected 3D reinforcing network inside the ABS matrix, enabling more efficient load transfer, better energy absorption under impact, and less permanent deformation under sustained stress. Unlike higher glass‑filled grades that trade surface quality for rigidity, ABS LGF20 strikes an ideal balance between structural performance, aesthetic quality and manufacturing efficiency.
For consumer electronics housings, automotive interior trim, power tool casings, and home appliance parts where appearance matters alongside structural performance, upgrading from short‑glass ABS GF20 to LFT‑G® ABS LGF20 delivers measurable performance gains without compromising surface quality or production yield. If your project requires a blend of toughness, precision, and premium finish, this comparison provides a clear performance benchmark.
LFT-G® Injection Molding Manufacturing Process
| Parameter | Recommended Range | Key Notes for LFT-G® ABS LGF20 |
|---|---|---|

FAQ
Q: What is the continuous use temperature for LFT-G® ABS LGF20?
A: LFT-G® ABS LGF20 supports long-term continuous service at 80°C to 90°C, with a significantly higher heat deflection temperature than unfilled ABS. It is well suited for indoor electronics, automotive interiors and household appliance environments, and can withstand short-term exposure to higher temperatures.
Q: Can ABS LGF20 be used for visible cosmetic parts directly?
A: Absolutely. Thanks to optimized long-fiber dispersion technology, this grade produces minimal surface fiber bloom and delivers a smooth, high-gloss finish directly from the mold. It also supports painting, electroplating and silk screening with excellent coating adhesion for higher aesthetic requirements.
Q: Does LFT-G® ABS LGF20 require special injection molding equipment?
A: No special machinery is required - standard injection molding machines work effectively. For best performance and surface quality, we recommend a low-compression screw and generously sized gating to preserve fiber length and reduce shear-induced fiber exposure. No special mold coatings are needed.
