LFT-G® ABS LGF30 is a 30% long glass fiber-reinforced ABS compound that delivers outstanding rigidity, impact strength, and cosmetic surface quality for structural and consumer applications. ✓ Balanced stiffness & impact toughness ✓ Cosmetic-grade molded surface ✓ Excellent dimensional stability & low warpage ✓ Lightweight alternative to metal and short-fiber grades
A Long-Glass ABS Built for Visible Structural Parts
LFT-G® ABS LGF30 is a 30% long glass fiber reinforced ABS composite developed for applications that combine structural rigidity, impact toughness, and a premium molded surface. It sits in a unique position between commodity ABS and engineering plastics - delivering the stiffness of a reinforced material while keeping the processability and appearance that make ABS the benchmark for visible components.
The 3D long-fiber skeleton inside the part dramatically improves load-bearing capacity, creep resistance, and dimensional accuracy over short-glass grades. Meanwhile, the ABS matrix preserves low-temperature impact strength, excellent flow, and compatibility with painting, plating, and printing - making ABS LGF30 a practical drop-in upgrade for structural housings, interior trim, and precision enclosures.
Target sectors include automotive interior components, consumer electronics frames, home appliance structural parts, and industrial equipment covers.

Why Engineers Choose ABS LGF30
01 - STIFFNESS
Long glass fibers raise flexural modulus to ~6,000 MPa, delivering the rigidity needed for thin-wall structural parts.
02 - TOUGHNESS
ABS matrix preserves impact strength even at low temperatures, reducing cracking risk in drop and vibration scenarios.
03 - APPEARANCE
Optimized dispersion minimizes fiber bloom, producing smooth surfaces ready for paint, plating, or direct use.
04 - STABILITY
3D fiber network reduces shrinkage and warpage, holding tight tolerances for precision assembly.
05 - DURABILITY
Continuous fibers resist creep and fatigue, maintaining part geometry under sustained and cyclic loads.
06 - PROCESSING
Good melt flow on standard injection machines enables complex ribs and thin sections without special equipment.

Where ABS LGF30 Performs
Instrument Panels & Door Trim
Substrates, brackets, and console structures use ABS LGF30 for its low-emission formulation, dimensional stability, and surface quality that supports direct painting or wrapping.
Frames, Housings & Back Covers
Laptop frames, TV backs, and smart device housings benefit from the material's high rigidity-to-weight ratio and cosmetic finish that reduces metal inserts and post-processing.
Structural & Functional Parts
Washing machine components, fan blades, and vacuum housings rely on ABS LGF30 for its resistance to vibration, chemicals, and long-term thermal cycling.
Covers, Housings & Tool Casings
Power tool casings, electronic enclosures, and control cabinets use ABS LGF30 for its impact toughness and compatibility with painting, plating, and printing.
Frequently Asked Questions
Q: How is ABS LGF30 different from standard ABS GF30?
Long glass fibers remain continuous within the pellet, forming a 3D network that delivers roughly 60% higher tensile modulus than short-glass ABS GF30, plus better creep resistance and dimensional stability - while preserving ABS's signature surface quality and impact toughness.
Q: Can ABS LGF30 be used for visible cosmetic parts?
Yes. Optimized fiber dispersion keeps surface fiber bloom minimal, so parts come out of the mold with a smooth finish ready for direct use, painting, electroplating, or silk-screening.
Q: What are the most important processing controls?
Pre-dry below 0.05% moisture, keep melt temperature between 220–250 °C, use mold temperature 45–75 °C for surface quality, and minimize residence time. A low-compression screw and generous gating preserve fiber length.
