LFT-G® ABS LGF40 Engineering Thermoplastic
High-Performance ABS Composite
LFT-G® ABS LGF40 is a premium 40% long glass fiber reinforced ABS engineered specifically for appliance structural components, automotive interior and exterior parts, and consumer electronics enclosures. Delivering exceptional impact resistance, superior surface finish, and outstanding dimensional stability, it is available as ready-to-mold pellets that simplify manufacturing and guarantee batch-to-batch consistency.
This long-fiber ABS material integrates the inherent surface gloss, chemical resistance, and excellent colorability of ABS with a rigid, continuous glass fiber network. Unlike conventional short glass fiber ABS compounds, the elongated glass strands establish a high-strength load-bearing structure that significantly enhances low-temperature toughness, creep resistance, and warpage control-critical characteristics for large, thin-walled parts operating under variable environmental conditions.
Supplied as uniform, resin-rich plastic pellets, ABS LGF40 flows smoothly through intricate molds, enabling complex geometries with ultra-low warpage and class A surface finish without secondary painting. This high-performance thermoplastic sets a new standard for cost-effective metal replacement in structural applications, offering significant weight savings, corrosion immunity, and design freedom without compromising mechanical integrity or aesthetic appeal.
Primary Material Characteristics
Class-A Surface & Structural Strength Integration
Unlike short glass fiber ABS that suffers from fiber exposure and poor surface quality, 40% long glass fiber reinforced ABS retains the inherent high gloss and smooth finish of pure ABS while delivering metal-like stiffness. This eliminates the need for secondary painting or coating processes, significantly reducing production costs and lead times.
Paintable Class-A Surface FinishUltra-Low Warpage for Large Thin-Wall Parts
The continuous long glass fiber network in LFT ABS significantly reduces anisotropic shrinkage compared to conventional SGF ABS. This results in minimal and predictable warpage, making it ideal for large, thin-walled components such as refrigerator liners, automotive door panels, and TV back covers that require tight dimensional tolerances.
Precision Molding for Large ComponentsSuperior Long-Term Creep Resistance
The entangled long glass fiber skeleton effectively restricts polymer chain movement under sustained static and dynamic loads. This grants ABS LGF40 outstanding resistance to creep deformation, ensuring parts maintain their shape and functionality over decades of service in appliance and automotive applications.
Durable Performance Under LoadBalanced Thermal & Chemical Resistance
40% glass filled ABS exhibits excellent heat deflection temperature (HDT) up to 110°C, making it suitable for most interior and under-hood non-high-temperature applications. It also retains ABS's inherent resistance to household chemicals, detergents, and oils, ensuring long-term durability in harsh daily environments.
Chemical & Heat ResistantExceptional Low-Temperature Impact Toughness
Long glass fibers act as effective crack arresters, bridging micro-cracks and absorbing impact energy. Combined with ABS's natural rubber phase, this results in significantly higher notched impact strength compared to short fiber grades, even at temperatures as low as -30°C, making it perfect for cold climate applications.
Damage-Tolerant Material BehaviorCost-Effective Metal Replacement Solution
LFT-G® ABS LGF40 offers an unbeatable combination of structural performance, aesthetic appeal, and low cost. It is the most economical long fiber thermoplastic material for replacing aluminum and steel in semi-structural parts, delivering up to 50% weight reduction and 30% total cost savings compared to metal alternatives.

Major Application Sectors
Refrigerator Door & Inner Liner Structures
Replacing cold-rolled steel and conventional ABS in refrigerator door panels, inner liners, and shelf supports, ABS LGF40 delivers equivalent structural rigidity while reducing weight by 40%. Its ultra-low warpage ensures perfect door sealing and dimensional consistency, while the inherent Class-A surface finish eliminates the need for secondary painting. Integrated molding design reduces assembly parts by 12, cutting production costs significantly.
Automotive Dashboard Skeletons & Door Modules
Engineered for automotive interior applications, 40% long glass fiber reinforced ABS replaces steel-reinforced PP composites in dashboard carriers and door panel substrates. It maintains exceptional dimensional stability across -40°C to 90°C temperature ranges, ensuring precise fitment of electronic components. The material's high impact resistance meets strict crash safety standards, while its excellent flowability enables complex integrated designs.
Large-Size TV Back Panels & Monitor Stands
Replacing aluminum alloys and stamped steel in 55"+ TV back panels and monitor support arms, LFT ABS achieves 50% weight reduction while maintaining superior flatness. It supports ultra-thin wall designs down to 1.5mm without sacrificing strength, and its low thermal expansion prevents screen distortion. Built-in mounting bosses and cable management features eliminate additional hardware, simplifying assembly.
Commercial Printer Frames & Medical Equipment Housings
Designed for demanding commercial and healthcare environments, glass-filled ABS replaces sheet metal in printer chassis, copier frames, and diagnostic equipment enclosures. Its high rigidity minimizes vibration during high-speed operation, improving print quality and equipment lifespan. The material's excellent chemical resistance withstands frequent disinfection, while its smooth, non-porous surface meets strict hygiene requirements.
FAQ
Q: What is LFT-G® ABS LGF40, and how does it differ from standard glass-filled ABS?
A: LFT-G® ABS LGF40 is a 40% long glass fiber reinforced ABS composite. Unlike conventional short glass fiber ABS, it retains a continuous fiber network that delivers 50% higher stiffness, 3x better impact strength, and ultra-low warpage, while maintaining ABS's inherent Class-A surface finish and excellent colorability.
Q: What mold temperature is recommended for LFT-G® ABS LGF40 to achieve Class-A surface quality?
A: For optimal surface finish on LFT-G® ABS LGF40 parts, maintain a mold temperature of 60-80°C. This ensures proper resin flow, eliminates fiber exposure, and achieves a high-gloss, paint-ready surface directly out of the mold, eliminating costly secondary finishing operations.
Q: Can LFT-G® ABS LGF40 replace aluminum in automotive interior structural components?
A: Yes. Use up to 25% regrind for non-critical parts and 10% or less for load-bearing components. Avoid regrind processed more than three times, as excessive fiber breakage will degrade performance.
