LFT-G® PP LGF60-C | The Unbreakable PP GF60 Upgrade
LFT-G® 60% Long glass fiber PP (Copo)
LFT-G® PP LGF60-NG06C is the apex of composite performance. Engineers searching for "PP GF60" are seeking one thing: the absolute maximum stiffness possible in a PP composite. However, standard short-fiber PP GF60 is notoriously brittle and fails catastrophically on impact. Our LFT-G®LFRT grade is the definitive solution.
We achieve this by fusing an extreme 60% long glass fiber skeleton with a high-impact Copolymer PP matrix. This synergy creates a "no-compromise" material that delivers metal-like rigidity for structural integrity, *plus* the massive energy absorption and low-temperature ductility of a copolymer. It is the ultimate metal-replacement material for harsh, dynamic environments.
√ Extreme Structural Rigidity: The 60% LGF load provides a flexural modulus over 12,000 MPa, challenging die-cast metals and eliminating creep.
√ Unmatched Impact Strength: The Copolymer base ensures the material remains ductile and fracture-resistant even in -40°C conditions where all other stiff plastics fail.
√ Superior Fatigue & Vibration Damping: The long glass fiber network is proven to withstand millions of micro-vibration cycles, making it ideal for parts like the Washing machine drum part.

Case Study: Wind Turbine Structural Ribs
Problem
A mid-size turbine manufacturer was using multi-part aluminum assemblies for structural ribs inside the nacelle. These were heavy, costly to fabricate, and suffering from fatigue and corrosion in harsh offshore (salt-mist) and cold-climate environments.
Solution
A single-shot part was designed with LFT-G® PP LGF60-C. The 60% long glass fiber (LFRT) structure provided the extreme stiffness needed to withstand high wind loads, while the Copolymer PP base provided critical -40°C impact resistance and total immunity to salt corrosion.
Result
The LFT part was 55% lighter than the aluminum assembly and reduced part cost by 40%. Zero failures were reported after 3 years, extending the component's service interval from 1 year to 5+ years.
Applications for Extreme "Stiff-Tough" LFT-PP
Washing Machine Drum Part (Spider)
This is a prime metal-replacement application. The 60% long glass fiber skeleton provides the extreme creep resistance needed to support the drum and withstand decades of high-speed spin cycles. The PP copolymer base provides 100% immunity to detergent corrosion, a common failure point for die-cast aluminum.
Automotive Battery Pack Enclosures
A critical EV component. It replaces heavy metal casings, providing the extreme stiffness (from 60% LFRT) to protect battery cells in a crash, while the copolymer PP base ensures it resists road debris impacts and remains ductile in cold climates.
Agricultural & Off-Road Panels
Replaces sheet metal on harvesters or ATVs. Unlike standard PP GF60 which would shatter, LFT PP LGF60-C has the toughness to withstand high-energy impacts from rocks and debris, combined with the stiffness to act as a structural part.
Key Questions Answered
1. Isn't a 60% glass fiber PP just extremely brittle?
A: A *short-fiber* 60% PP would be, yes. That is the key difference. Our LFT-G® grade combines two technologies: 1) A Copolymer PP base, which is inherently tough, and 2) Long Fibers (LFRT), which create a skeletal network that actively stops cracks from propagating. The result is a unique material that has the stiffness of a 60% filling but retains the toughness of a high-end engineered composite.
2. What is the key difference between LFT PP LGF60-C (Copolymer) and LGF60-H (Homopolymer)?
A: The choice is "Maximum Stiffness vs. Survival." The Homopolymer (H) grade offers the absolute highest stiffness and heat resistance. This Copolymer (C) grade (NG06C) trades a very small amount of stiffness (approx. 5-10%) for a massive gain (300-400%) in impact strength, especially at low temperatures. For any part that operates in a harsh, dynamic, or cold environment, this Copolymer grade is the superior choice.
