LFT-G® PP GF40 Natural – The Engineering Standard for Structural Plastics
LFT-G® PP LGF40 NG04 (Model: LFT-G PP-NG04) is a high-performance 40% long glass fiber reinforced homopolymer composite. This natural-grade formulation is specifically designed for engineers who require a "blank canvas" for precision custom coloring without sacrificing the mechanical integrity of a massive 9500 MPa modulus.
Unlike standard short glass fiber pp, our pultrusion technology preserves continuous 10-12mm fibers within the pellet. This internal 3D structural skeleton delivers extraordinary fatigue endurance and impact mastery, making it the premier choice for structural components in the automotive and industrial machinery sectors.
Key Performance Pillars:
- ● Color Flexibility: Unpigmented matrix allows for vibrant, accurate color matching.
- ● Metal-Like Rigidity: Replaces die-cast aluminum with a high stiffness-to-weight ratio.
- ● Hydrolysis Resistance: Superior performance in wet environments vs. standard Nylon.
- ● Precision Molding: Ultra-low shrinkage (0.1% - 0.3%) for tight-tolerance parts.

Structural Applications: Purity Meets Power
Premium Home Appliances
In high-end kitchen appliances and vacuum cleaners, internal chassis components must be exceptionally rigid to support high-speed motors. The Natural long glass fiber PP provides the necessary stiffness while ensuring the final product's cosmetic exterior matches the custom brand color perfectly.
Automotive Front-End Modules
Engineered to replace die-cast metals in structural carriers and sub-frames. The 9500 MPa modulus ensures alignment of headlights and sensors is maintained under harsh vibration. The natural matrix is preferred for under-hood parts where raw material purity and high thermal resistance are the priorities.
Industrial Fluid Systems
Perfect for industrial pump impellers and valve bodies. Unlike metallic parts, our 40% LGF PP is immune to corrosion. The 3D fiber network prevents "blade creep" at high RPMs, ensuring constant flow rates and long-term dimensional stability in submerged conditions.
Frequently Asked Questions (FAQ)
Q: Is PP LGF40 Natural easily colorable?
A: Absolutely. The "Natural" formulation (NG04) is designed to accept universal masterbatches during the injection process. It ensures vibrant and consistent color across large production runs, making it the preferred choice for consumer electronics and white goods where cosmetic appearance is as important as structural strength.
Q: How does the impact strength of LGF40 compare to SGF40?
A: Standard SGF40 (short fiber) is inherently brittle. LFT-G® technology preserves fiber length (10-12mm), creating an entangled skeleton that absorbs 2-3 times more shock energy. This prevents catastrophic cracking in safety-critical parts like automotive brackets or power tool housings.
Q: Can this material replace die-cast Aluminum?
A: Yes. With a flexural modulus of 9500 MPa, it matches the functional rigidity needed for many structural frames. Switching to LGF40 cuts part weight by ~45%, eliminates expensive secondary CNC machining, and removes the risk of corrosion, significantly lowering the total part cost.
