Industry Applications: Extreme Structural Demands
Washing Machine Structural Components
Widely utilized for washing machine plastic part design, particularly bearing spiders and inner tubs. The 50% LGF matrix offers unparalleled fatigue resistance during high-speed spin cycles. Its chemical immunity to harsh detergents and absolute dimensional precision prevents motor misalignment, extending machine life by 30%.
EV Battery Trays & Side Rails
Electric vehicle structural parts demand massive specific stiffness. Our 50% black long glass fiber PP yields the load-bearing capacity of steel with 50% less weight. The UV-stable black finish provides the premium OEM aesthetic required for exposed underbody protection modules and battery pack covers.
Frequently Asked Questions (FAQ)
Q: Is 50% fiber loading too brittle for impact-prone parts?
A: With short fibers, yes. However, LFT-G® uses 10-12mm long glass fiber. This continuous network acts as an energy dissipator, meaning LGF50 actually has 3-4X higher impact strength than standard 30% or 40% short-fiber PP. It flexes without fracturing under severe shocks.
Q: Can Black PP LGF50 truly replace Die-Cast Aluminum?
A: Yes, definitively. In functional assemblies like structural brackets or radiator tanks, LGF50 matches the stiffness required while eliminating secondary machining. Furthermore, it completely removes the risk of galvanic corrosion, a massive advantage for industrial fluid systems.
Q: How does the UV stability hold up in outdoor industrial use?
A: The model LFT-G PP LGF50-BG04 is integrated with deep black high-quality carbon pigments. This provides inherent UV stabilization throughout the material matrix, preventing surface chalking and mechanical degradation even after years of direct sunlight exposure.

LFT-G® PP LGF40 1 Black (Model: PP-BG04) is an industrial-grade thermoplastic formulated for extreme stiffness. It combines a durable polypropylene matrix with a 40% long glass fiber skeleton, integrated with deep black pigments for premium UV resistance and surface aesthetics.
Standard short fiberglass limits performance. Our pultrusion process retains 10-12mm continuous fibers, creating a 3D structural mesh inside the molded part. This fundamentally eradicates brittleness, offering a lightweight metal replacement with a massive 9,500 MPa flexural modulus.
Core Engineering Advantages:
- ● Absolute Rigidity: 9,500 - 10,500 MPa stiffness replaces heavy aluminum brackets.
- ● Cosmetic Excellence: Deep black matrix requires zero secondary painting.
- ● Zero Moisture Issue: Retains full mechanical dimensions, outperforming PA6 in humidity.
- ● Vibration Damping: 3D fiber network prevents high-frequency fatigue failure.
DFM Guide: Molding Long Glass Fiber PP
To achieve maximum structural strength, preserving fiber length during injection molding is critical. Follow our engineering best practices to unlock the full potential of glass fiber pp composites.
Screw & Barrel
Use a low-compression ratio screw (2:1 to 2.5:1) with a deep feed flight. Avoid high-shear mixing elements to prevent premature fiber breakage.
Gate Design
Avoid pin-point gates. Use generous edge, fan, or sprue gates (minimum 4mm diameter) to allow the 10mm fibers to flow smoothly into the cavity.
Process Parameters
Maintain low back-pressure (< 50 psi) and moderate injection speeds. High mold temperatures (60-80°C) enhance the sleek black surface finish.

Robotics & Automation Arms
In industrial robotics, minimizing mass while maintaining rigid precision is crucial. The sleek black 40% LGF matrix dramatically reduces the inertia of moving robotic arms compared to aluminum, increasing operational speeds and battery efficiency without sacrificing structural strength.
Automotive Battery Covers
Protects sensitive EV battery modules from road debris and vibrations. The jet-black, UV-stable finish looks premium under the hood, while the 9,500 MPa stiffness prevents the cover from bowing or warping under high thermal loads.
Frequently Asked Questions (FAQ)
Q: How does the Black PP GF40 surface finish look after molding?
A: By utilizing high-quality pigments and optimizing the pultrusion process, we ensure excellent resin dispersion. With a hot mold (above 60°C), the part achieves a smooth, resin-rich black surface, eliminating the "floating fiber" appearance common in standard high-glass compounds.
Q: Is LGF40 significantly stronger than SGF40 (Short Glass Fiber)?
A: Yes. While tensile stiffness is similar, the long glass fiber network massively boosts impact strength and fatigue endurance. SGF40 parts easily crack under sudden shocks or prolonged vibration, whereas LGF40 parts absorb the energy and remain intact.
Q: Can it replace PA6-GF40 in outdoor applications?
A: Absolutely. Nylon (PA6) absorbs moisture, which can cause swelling and weakness outdoors. PP LGF40 absorbs zero moisture, and our BG04 model includes deep black carbon compounding that provides inherent UV resistance, making it superior for outdoor exposure.
