LFT-G® PP LGF50-C | The Ultimate Unbreakable PP GF50
LFT-G® 50% Long glass fiber PP (Copo)
LFT-G® PP LGF50-NG05C is the definitive answer for engineers seeking the stiffness of "PP GF50" without its critical flaw: brittleness. Standard PP GF50 (short fiber) is notoriously brittle and fails catastrophically on impact, especially in the cold. This material is the ultimate upgrade, combining a massive 50% long glass fiber (LFRT) load with a high-impact Copolymer PP matrix.
The result is a no-compromise composite. The 50% long glass fiber skeleton provides metal-like stiffness and creep resistance, while the copolymer base ensures the part remains ductile and absorbs massive energy, even in arctic conditions. It is engineered for true structural metal replacement in the harshest environments.
√ Ultimate "Stiff-Tough" Balance:
√ Extreme Environment Durability:
√ Structural Metal Replacement:
Ideal for replacing heavy, corrosion-prone die-cast aluminum in high-vibration, high-impact components (e.g., a washing machine drum part).
Typical Material Properties
The following values are typical data for LFT-G® PP LGF50 -NG05C (natural copolymer grade) and are for reference only. Please contact us for the official Technical Data Sheet (TDS).
The following values are recommendations. We recommend desiccant / dry air dryers (moisture content below 0.1%).
To minimize fiber breakage and ensure optimal performance, a low-compression, general-purpose screw is highly recommended.

Case Study: Mining Equipment Structural Housing
Problem
A manufacturer of mining sensors needed a housing that could be mounted on heavy vibration equipment. The existing die-cast aluminum housing was heavy, expensive, and its seals failed due to vibration. It also cracked from rock impacts in sub-zero mine shafts.
Solution
LFT-G® PP LGF50-C was chosen. The 50% long glass fiber (LFRT) structure provided the extreme stiffness needed to maintain dimensional stability and protect the electronics. The Copolymer PP base absorbed the constant vibration and provided the critical low-temperature toughness to resist impacts.
Result
The LFT part was 60% lighter than the aluminum one. Field tests showed a 500% increase in service life, as it eliminated both vibration and impact failures. This led to a 70% reduction in warranty claims for the customer.
Applications for Extreme "Stiff-Tough" LFT-PP
Washing Machine Drum Part (Spider)
This is a prime metal-replacement application. The 50% 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 Bumper Beams
A critical safety component where LFT PP LGF50-C excels. It provides the high stiffness (from 50% LFRT) to manage crash forces and the high impact (from Copolymer PP) to absorb energy without shattering, passing stringent low-temperature crash tests.
Snowmobile Structural Components
The ultimate test of low-temperature toughness. This material is used for chassis and suspension components that must withstand constant vibration and severe impacts from rocks and ice in sub-zero conditions, replacing heavier, failure-prone metals.
Key Questions Answered
1. What is the benefit of this 50% Copolymer (C) vs the 50% Homopolymer (H) grade?
A: The choice is about "Stiffness vs. Survival." The Homopolymer (H) grade offers the absolute maximum stiffness, but it is more brittle. This Copolymer (C) grade retains about 90-95% of that stiffness but adds 3–4 times the low-temperature impact strength. For parts in unpredictable environments (like automotive, outdoor, or appliance), this Copolymer grade is the superior, more reliable choice.
2. Can this material really replace a metal "Washing Machine Drum Part"?
A: Absolutely. It is a prime application for parts like the drum spider. The 50% long glass fiber (LFRT) skeleton provides the extreme creep resistance to withstand decades of high-speed spin cycles. The PP copolymer base provides 100% immunity to corrosion from detergents, which is a common failure point for die-cast aluminum.
