LFT-G® PP GF30 (LGF30) – High Impact Structural Homopolymer
Details
LFT-G® PP GF30 (Model: LFT-PP-GF30-NG03) redefines the limits of standard long glass fiber-filled polypropylene. By fortifying a high-crystallinity homopolymer matrix with 30% continuous long glass fiber, we deliver an engineering composite that strikes the perfect balance between robust rigidity (7,500 MPa) and extreme impact toughness.
√35 kJ/m² Impact Mastery
√Outperforms Standard Short GF30
√Zero Moisture Expansion
√Lightweight Aluminum Alternative
LFT-G® PP GF30 (LGF30) High Impact Structural Polymer
While generic chopped PP GF30 is notoriously brittle, our continuous pultrusion technology preserves 10-12mm fibers inside every pellet. This creates a resilient 3D internal skeleton during injection molding, making it the definitive lightweight metal replacement for domestic appliances and automotive safety components.
Failure Mode Analysis: Upgrading from Short Fiber
Engineers often face catastrophic field failures when using standard short fiber PP GF30. See how our Long Fiber (LGF30) architecture actively mitigates these risks.
⚠️ Risk: Cold Temperature Impact
Standard PP GF30: Homopolymer base becomes highly brittle below 0°C. Short fibers cannot absorb sudden kinetic shocks, leading to shattering.
LFT-G® Solution: The 10mm continuous fiber mesh acts as a mechanical shock-absorber, delivering an incredible 35 kJ/m² impact strength, entirely negating the homopolymer brittleness.
✅ Advantage: Fatigue Endurance
Standard PP GF30: Cyclic vibrations cause short fibers to pull out of the resin matrix, leading to rapid fatigue cracking.
LFT-G® Solution: The intertwined long fiber skeleton physically bridges micro-cracks, allowing components to survive millions of high-frequency vibration cycles in motor housings.

Industry Applications: High Impact Replacement
Domestic Appliances & Washing Machines
Perfectly optimized for domestic appliance components like washing machine bearing spiders. The 30% long fiber matrix guarantees outstanding dimensional stability during intense spin cycles and absorbs zero moisture, outperforming brittle nylons in wet environments.
Automotive Shifter Bases & Modules
Center console shifters require stiff handling without compromising crash safety. LFT-G®pp gf30 provides the rigid Homopolymer feel combined with 35 kJ/m² impact toughness, allowing automakers to pass strict knee-impact crash tests while reducing weight.
Frequently Asked Questions (FAQ)
Q: Is it difficult to injection mold Long Glass Fiber (LGF30)?
A: Standard machines work perfectly. However, to preserve the fiber length, we strongly advise using low back-pressure (<50 psi), low-compression screws, and large gate sizes (minimum 3mm). This ensures the final part achieves its true high-impact potential.
Q: How does PP GF30 compare to PA6 GF30 in metal replacement?
A: The critical advantage is moisture immunity. Nylon (PA6) absorbs water, significantly lowering its strength and causing dimensional warping. LFT-G® PP GF30 absorbs virtually zero moisture, ensuring constant structural rigidity in highly humid or wet conditions.
