LFT-G® PP LGF50|The Ultimate PP GF50 for Extreme Impact & Stiffness
LFT PP LGF50 Copolymer: The PP GF50 Upgrade for Unbreakable Performance
Engineers searching for the maximum performance of a "PP GF50" often face a critical trade-off: stiffness versus toughness. LFT-G® PP LGF50-NG05C eliminates this compromise. It is a premier long-fiber composite that elevates the concept of PP GF50 by combining an ultra-high 50% long glass fiber matrix.
tradictory goals: the extreme stiffness and strength derived from its 50% fiber content, and the exceptional low-temperature impact resistance inherent to a copolymer base. This creates a material that is not only incredibly strong and rigid for heavy load-bearing, but also remains ductile and fracture-resistant in the harshest sub-zero conditions. It is the definitive material for mission-critical , heavy-duty industrial equipment, and professional gear designed for arctic environments.
It is the no-compromise solution for applications demanding the absolute peak of both structural rigidity and impact durability.
Think of our material's properties as a double helix. LFT-G® intertwines two crucial performance strands-Stiffness from the long glass fiber, and Toughness from the copolymer matrix-into a single, superior material.
The Stiffness Strand (LGF50)
The 50% long glass fiber content forms a dense, rigid skeleton. This strand provides:
• Metal-like Flexural Modulus
• Long-Term Dimensional Stability
The copolymer matrix acts as a shock absorber. This strand provides:
• Extreme Low-Temp Impact Strength

A leading agricultural equipment manufacturer needed to replace heavy, dent-prone steel side panels on their flagship combine harvester. The replacement had to be a large, single-piece molding that could withstand severe impacts from rocks and debris kicked up during harvesting, function in climates from scorching summer heat to freezing winters, and provide structural support for access ladders and service points.
LFT-G® PP LGF50-NG05C was specified for its unique combination of properties. The 50% long glass fiber provided the rigidity necessary to act as a structural panel, eliminating the need for extra metal bracing. The copolymer base ensured that even if a large rock struck the panel at -20℃, it would absorb the energy and flex rather than shatter, preventing catastrophic failure and machine downtime.
The new LFT panels reduced overall vehicle weight by 150 kg, leading to improved fuel efficiency. Field tests showed a 500% improvement in impact resistance over the previous design, dramatically reducing field service claims for damaged panels. The single-piece design also streamlined manufacturing and gave the harvester a more modern, seamless aesthetic.
Replaces heavy steel beams. This material provides the extreme stiffness to pass crash safety standards while offering superior low-temperature impact performance and significant weight savings.
For containers that must protect sensitive electronics from drops and extreme climates, from arctic to desert. The combination of rigidity and toughness ensures mission readiness and equipment safety.
Engineered to replace wood or standard plastics. It provides the high stiffness to prevent sagging in automated racking systems and the low-temp toughness to withstand forklift impacts in freezer environments.
1. Is PP GF50 a real material designation?
A: While "PP GF50" is a commonly searched term for 50% glass-filled polypropylene, the more precise engineering term distinguishes between fiber lengths. "PP GF50" typically refers to short fiber, while "PP LGF50" like our LFT-G® grade refers to long fiber. We use both terms to help users find our superior long-fiber solution, which offers dramatically better impact and creep performance than short-fiber alternatives.
2. Why choose a Copolymer base for a high-stiffness LGF50 material?
A: It's for creating a "best of both worlds" composite. While a homopolymer base would be even stiffer, it would also be more brittle, especially with such a high fiber load. By using a copolymer matrix, we retain a very high level of stiffness while introducing a critical safety net of low-temperature toughness, making the material far more reliable for real-world dynamic applications.
3. Does a 50% glass fiber PP have good surface aesthetics?
A: Due to the very high fiber content, LFT PP LGF50 is primarily used for structural, functional components where mechanical performance is the priority over Class-A surface finish. While the surface is uniform, the high fiber loading will be visible. For applications requiring both strength and high-quality aesthetics, a lower glass content (like LGF30) or a different polymer system might be considered.
