High-Performance 60% Long Glass Fiber Reinforced Homo Polypropylene, is the performance upgrade of PP GF60 short fiber composite
√ The Peak of Impact Resistance
√ Superior Low-Temp Toughness
√ Excellent Stiffness & Toughness Balance
LFT-G® PP LGF60-H | The Ultimate Structural PP GF60
LFT-G® 60% Long glass fiber PP (Homo)
LFT-G® PP LGF60-NG06H 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 Homopolymer 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 13,000 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: Industrial HVAC Blower Housing
Problem
A large industrial blower unit, housed in a multi-part fabricated steel assembly, was failing. The steel was heavy, expensive, and transmitted excessive noise and vibration. The unit also required operation in high-heat (80°C+) factory environments.
Solution
A single-shot part was designed with LFT-G® PP LGF60-H. The 60% long glass fiber (LFRT) structure provided the extreme stiffness needed to maintain dimensional stability and motor alignment at high temperatures. The PP base offered superior vibration damping compared to steel.
Result
The LFT part consolidated 8 steel pieces into one. It was 60% lighter, reduced assembly time by 50%, and lowered unit cost. The vibration damping effect also resulted in a 15% reduction in perceived noise (dBa).
Applications for Extreme Stiffness LFT-PP (Homo)
Washing Machine Structural Base
This is a true metal-replacement application. The extreme stiffness of LFT PP LGF60-H allows it to serve as the entire load-bearing chassis of the appliance, replacing concrete or multi-part metal frames. It provides the rigidity and vibration damping needed to manage high-speed spin cycles, a key use for a Washing machine drum part system.
Automotive Sunroof Frames
A perfect application for LFT-G® PP LGF60-H. The material's extreme stiffness and high thermal resistance (HDT >160°C) prevent the large, thin frame from warping under the sun's heat. This ensures a perfect seal against wind and water for the life of the vehicle, replacing heavier, complex aluminum frames.
Industrial Pump Baseplates
Replaces heavy, corrosion-prone cast iron. The high stiffness and creep resistance of the 60% long glass fiber (LFRT) structure ensures the pump and motor stay in perfect alignment, while the PP base offers total chemical resistance and damps vibration, reducing noise and extending service life.
Key Questions Answered
1. What is the stiffest polypropylene material?
A: Long-fiber reinforced polypropylene (LFRT) is significantly stiffer than standard short-fiber grades. LFT-G® PP LGF60-H (60% long glass fiber Homopolymer) represents the peak of stiffness, with a flexural modulus approaching 13,000 MPa, making it a direct competitor to die-cast metals like aluminum.
2. What are the disadvantages of high glass fiber content (e.g., PP GF60)?
A: With standard *short* fibers, high fillings (like PP GF60) lead to extreme brittleness and very poor impact strength. This is the exact problem our LFRT technology solves. By using long glass fiber, we create an internal skeleton that stops cracks, retaining significant toughness even at 60% fiber content, a feat SGF cannot achieve.
3. Can polypropylene composites replace die-cast aluminum?
A: Yes, absolutely. For many structural parts (like sunroof frames or washing machine drum part systems), LFT-G® PP LGF60-H is a superior choice. It offers a much better stiffness-to-weight ratio (over 50% lighter than aluminum), is corrosion-proof, and allows for part consolidation, which drastically reduces manufacturing cost and complexity.
