What is ABS LGF40?
LFT-G® ABS LGF40 is a 40% long glass fiber reinforced acrylonitrile-butadiene-styrene compound, engineered for high-stiffness, semi-structural applications where dimensional stability and heat resistance are critical. The long glass fiber network creates a continuous 3D reinforcement skeleton, distributing stress evenly and reducing anisotropic shrinkage by up to 60%.
Core Capabilities
Performance Edge: Long vs Short Fiber
Performance comparison between LFT-G® ABS LGF40 (long glass fiber, 40% reinforcement) and standard short-fiber ABS GF40. The long glass fiber architecture delivers a clear performance advantage across all key mechanical properties, making it the preferred choice for structural and load-bearing applications.
Long-fiber advantage: +28% tensile strength, +33% flexural strength, +133% impact resistance – ideal for structural metal replacement.

Applications
Automotive Lightweight
Instrument panels, door modules, EV battery supports. Metal-like stiffness at 30% weight reduction. ABS LGF40 enables complex geometries with excellent dimensional stability and long-term fatigue resistance under dynamic loads.
Industrial Automation
Pump housings, fan blades, robotic grippers. Outstanding creep resistance and chemical resistance to oils and coolants, ensuring reliable 24/7 operation in harsh factory environments.
E-Mobility & Power Tools
Battery enclosures, thermal management components, power tool bodies. High heat deflection (>90°C) and vibration resistance make it ideal for demanding electrical applications.
Q: Does ABS LGF40 meet UL, RoHS, and REACH compliance for global markets?
A: Yes. ABS LGF40 is UL-recognized (HB flammability rating), fully RoHS compliant, and REACH SVHC-free. Full material declarations and test reports are available upon request, supporting your global regulatory and supply chain requirements.
Q: How does ABS LGF40 improve design efficiency?
A: Long fibers enable thinner, lighter parts with minimal warpage (0.10–0.30% shrinkage), allowing near-net-shape molding that cuts secondary operations and lowers assembly costs.
Q: Is ABS LGF40 reliable in humid or thermal cycling conditions?
A: Yes. With low moisture uptake and a 93°C HDT, it retains dimensional stability and strength under fluctuating temperatures and humidity, outperforming short-fiber grades in outdoor environments.
