Wear Resistance LGF50 TPU Composite
What Is LGF50 TPU?
LGF50 TPU is a high-performance thermoplastic composite material based on thermoplastic polyurethane (TPU) with 50% long glass fiber (LGF) as the reinforcing skeleton.
When the parts require higher load-bearing capacity, structural rigidity and dimensional stability, ordinary TPU is often limited.
LGF50 TPU is a "high-toughness TPU + high-rigidity glass fiber" composite solution. By adding 50% long glass fibers, LGF50 TPU changes the force-bearing mode of the single polymer matrix of TPU.
Why is it "LGF (long glass fiber)" instead of "SGF"?
One of the main differences between LGF50 TPU and ordinary GF-TPU lies in the length of the glass fibers and the reinforcing structure.
Long glass fiber reinforcing structure The longer glass fibers can form a more continuous reinforcing network within the TPU matrix.
When the part is subjected to stretching, bending or impact: external load → TPU matrix → glass fiber network → dispersion and transfer of stress. This structure helps to reduce local stress concentration and improve the overall structural load-bearing efficiency.
LGF50 TPU: Core Advantages
High-strength enhancement
The 50% long glass fiber content enables the material to further evolve from the functional elastic material of traditional TPU to a structural composite material.
High rigidity, but retaining the TPU matrix characteristics
One obvious feature of ordinary TPU is its high flexibility. LGF50 TPU significantly improves the structural rigidity of the material through a high proportion of long glass fibers.
High impact resistance
TPU itself has good toughness, and the long glass fibers can form an enhanced framework. When combined, it can balance: rigidity + toughness + impact resistance.
Excellent wear resistance
TPU is one of the engineering thermoplastic materials with outstanding wear resistance.
Excellent dimensional stability
After being reinforced with long glass fibers, the dimensional stability of the material has been significantly improved.
When can LGF50 TPU be Selected?
- When regular TPU is "too soft"
- When short glass fiber TPU "does not have sufficient enhancement efficiency"
- When PA/GF is "too rigid or not wear-resistant enough"
- When metal is "too heavy"

FAQ
Q: What are the differences between LGF50 TPU and ordinary TPU?
A: Ordinary TPU places greater emphasis on flexibility, wear resistance and impact resistance; LGF50 TPU, while retaining the advantages of the TPU matrix, significantly enhances rigidity, strength and dimensional stability.
Q: Is LGF50 TPU wear-resistant?
A: TPU itself has excellent wear resistance properties. After being reinforced with long glass fibers, it can further meet the requirements of some structural wear-resistant applications.
Q: What is the length of the glass fibers in LGF50 TPU?
A: The original length of the long fibers in a typical LGF product is approximately 5–25 mm, and the common length is around 10–12 mm. Within the range, the length can be customized according to your needs.
Q: Can LGF50 TPU be injection molded?
A: Yes. LGF50 TPU can be used for injection molding and is suitable for the mass production of complex structural components.
