LFT-G® PP LGF50-C | The High-Impact Upgrade for PP GF50
Product Description & Features
LFT-G® PP LGF50 -NG05C is the ultimate toughness upgrade for designs specifying "PP GF50". Standard PP GF50 (short fiber) is often selected for its stiffness, but it is notoriously brittle and fails catastrophically upon impact, especially in cold weather. LFT-G® PP LGF50-NG05C is a copolymer (Copo) grade specifically engineered to solve this problem.
By combining a 50% long glass fiber network with a high-impact copolymer matrix, this material provides unparalleled durability. The long fibers create a "rebar-like" skeleton that stops cracks, while the copolymer base absorbs impact energy.
√ Extreme Impact Resistance: Offers 3–5 times the impact strength of standard PP GF50, preventing failures from drops or collisions.
√ Superior Low-Temp Toughness: Remains ductile and fracture-resistant in sub-zero conditions, where homo polymer grades (including SGF PP GF50) become extremely brittle.
√ Excellent Processability: Provides a great balance of toughness and melt flow, making it ideal for molding complex, durable parts with features like snap-fits and bosses.
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: Washing Machine Drum Spider
Challenge
A major appliance OEM was replacing die-cast aluminum in their premium washing machine drum spider. While standard PP GF40 offered corrosion resistance, it failed due to creep (deforming under high-speed spin) and low-temperature impact (cracking during winter transport).
Solution
LFT-G® PP LGF50-C was chosen. The 50% long glass fiber (LFRT) structure provided the extreme stiffness and creep resistance needed to handle decades of spin cycles. The copolymer (Copo) base ensured the part would not crack from impacts, even at -30°C.
Result
The LFT part successfully replaced aluminum, offering a 40% weight saving and 25% cost saving. It passed all 10-year life cycle tests, eliminating both creep and impact failures, and improving the machine's overall durability.
Applications for High-Toughness & Stiffness PP LFT
EV Battery Trays
A perfect metal-replacement part. LFT PP LGF50-C provides the stiffness to protect battery cells, the impact resistance for road debris, and the chemical resistance to battery coolants.
Military & Defense Cases
For applications where equipment *must* survive. This material provides extreme rigidity to prevent flexing, and the copolymer toughness to absorb high-energy drops, even in arctic conditions.
Agricultural Machinery Panels
Replaces sheet metal. LFT PP LGF50-C offers the stiffness to act as a structural part, but unlike metal, it resists denting and has the toughness to withstand rock and debris impacts.
Key Questions Answered
1. What is the benefit of a 50% Copolymer (PP LGF50-C) vs 50% Homopolymer (PP LGF50-H)?
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), the Copolymer grade is the superior, more reliable choice.
2. Can LFT PP LGF50-C really replace a metal "Washing Machine Drum Part"?
A: Absolutely. It is a prime application. It replaces die-cast aluminum spiders. The 50% long glass fiber (LFRT) skeleton provides the extreme creep resistance to withstand years of high-speed spinning. The PP base offers total immunity to corrosion from detergents and water, which is a common failure point for aluminum.
3. Why use "PP GF50" in the title if the product is LFT PP LGF50?
A: This is an SEO strategy. More customers search for the general term "PP GF50" (a short-fiber designation) than the specific term "LGF50." We use the high-traffic term to attract users and then present our LFT-G® long-fiber (LFRT) product as the high-performance upgrade that solves the brittleness and creep issues of standard PP GF50.
