LFT-G® PP LGF50 | The Ultimate PP GF50 for Stiffness & Metal Replacement

Product Description & Features

LFT-G PP LGF50-H material - ultimate stiffness homopolymer LFT-G^® PP LGF50 -NG05H is the definitive structural upgrade for designs specifying "PP GF50". While standard short-fiber PP GF50 offers high stiffness, it fails in true structural roles due to poor creep resistance and brittleness. LFT-G^® PP LGF50-NG05H is a homopolymer (Homo) grade with 50% long glass fiber (LFRT), engineered for one purpose: maximum stiffness and metal replacement.

The 50% long glass fiber content forms an incredibly dense, rigid internal "skeleton" within the molded part. This structure provides a flexural modulus that directly competes with die-cast aluminum, but at a fraction of the weight.

√ Extreme Stiffness: Delivers the highest rigidity in the PP family, ideal for large parts that cannot flex or deform under heavy load.
√ Superior Creep Resistance: Unlike SGF PP GF50, the LFRT network prevents material "sag" over time, even at elevated temperatures, making it essential for structural components.
√ Metal Replacement: Offers a viable, lightweight, and cost-effective alternative to die-cast aluminum or magnesium for major structural parts (e.g., appliance chassis, automotive frames).

A single-piece, lightweight LFT PP LGF50 sunroof frame

Weight: 2.5 kg (-52%)
Process: Single-shot injection molding
Result: Met all rigidity targets, reduced cost by 30%, and eliminated condensation issues.

Applications for Extreme Stiffness LFT-PP

A large, structural base for a washing machine, replacing concrete or metal

Appliance Structural Chassis

Used as the primary structural base for high-end washing machines. LFT PP LGF50 provides the extreme stiffness needed to manage high-speed spin vibrations and prevent flexing, while offering total corrosion resistance to detergents. It replaces heavier, multi-part metal frames or concrete counterweights.

Automotive Front-End Modules

A classic metal-replacement application. The high modulus of LFT PP LGF50 is essential for this large component, which must support the radiator, headlights, and hood latch, maintaining precise alignment under all driving conditions and temperatures, all while saving critical weight.

A large structural frame for an industrial machine base

Industrial Machine Bases

Replaces machined aluminum or steel weldments for the frames of robotics or conveyor systems. The key benefit is long-term reliability; the material's high creep resistance ensures that critical alignments are held for millions of cycles without sagging or deformation.

Key Questions Answered

1. Why use "PP GF50" in the title if the product is LFT PP LGF50?

A: This is an SEO strategy. More engineers 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, then present our LFT-G® long-fiber (LFRT) product as the high-performance upgrade that solves the critical creep and structural failures of standard PP GF50.

2. What is the difference between this Homopolymer (H) grade and the Copolymer (C) PP LGF50?

A: The choice is "Maximum Stiffness vs. Toughness." This Homopolymer (H) grade is engineered for one thing: the highest possible stiffness and heat resistance. The Copolymer (C) grade (like our NG05C) trades about 5-10% of its stiffness for a massive 300-400% gain in impact toughness, especially in the cold. If your part is a static frame, choose (H). If it might get hit, choose (C).

3. Can LFT PP LGF50 genuinely replace die-cast aluminum?

A: Yes, absolutely. For many structural parts, it's a superior choice. While aluminum is heavier and technically stiffer, LFT PP LGF50 has a much better stiffness-to-weight ratio. It allows you to mold a complex, single-piece part with deep ribs that is just as rigid as a metal assembly, but 50% lighter, corrosion-proof, and far cheaper to manufacture.
