LFT-G® TPU-LGF40 Long Glass Fiber Reinforced Polyurethane Composite
TPU-LGF40: Redefining Flexibility with Structural Rigidity
TPU-LGF40 is more than a flexible material-it is a hybrid performance solution. Reinforced with 40% long glass fibers, it maintains the inherent resilience of TPU while introducing exceptional structural strength and dimensional stability, making it uniquely capable of supporting sustained loads and resisting deformation under repeated stress.
This composite delivers an outstanding rigidity-to-toughness balance, offering both high modulus and impact absorption in a single system. It excels in fatigue and creep resistance, maintaining its shape and functionality over time, even in demanding dynamic applications. Additionally, it provides reliable chemical and abrasion resistance, ensuring consistent performance across diverse environments and mechanical conditions.
From vibration-damping structural components and durable industrial flexures to high-wear automotive mounts and precision sporting goods, TPU-LGF40 enables designs that demand both movement and endurance. It enables engineers to replace traditional rigid parts with intelligent, resilient alternatives, creating products that are not only strong and durable but also adaptive and lasting in real-world use.

Key Advantages of LFT-G® Long Glass Fiber Reinforcement
- → Superior Impact Resistance: Long fibers create a continuous reinforcement network that absorbs and distributes impact energy more effectively than short fibers.
- → Enhanced Creep & Fatigue Resistance: The longer fiber length provides better load transfer and resistance to deformation under sustained or cyclic loads.
- → Improved Mechanical Properties: Longer fibers result in higher tensile and flexural strength due to better fiber-matrix bonding and load distribution.
- → Better Dimensional Stability: Reduced warpage and shrinkage compared to short fiber reinforced materials.
Why Long Fibers Outperform Short Fibers
Long glass fibers create a continuous, interlocking reinforcement network within the polymer matrix. This allows for more efficient load transfer along the fiber length, resulting in significantly improved impact resistance, fatigue life, and creep resistance compared to short fibers, which act as isolated reinforcement points with stress concentrations at fiber ends.

FAQ
Q: What makes TPU-LGF40 unique?
A: It combines the flexibility of TPU with the strength of engineering plastics. The 40% long glass fiber network acts like a rigid skeleton inside an elastic matrix, delivering an unmatched rigidity-toughness balance.
Q: Where does it outperform short glass fiber TPU?
A: In impact resistance, creep resistance, and fatigue life. Long fibers create a continuous reinforcement network, while short fibers act as isolated weak points-especially under dynamic or sustained loads.
Q: What's the real-world benefit?
A: Parts last longer and perform more reliably. Whether it's a damping joint, structural mount, or foldable component, TPU-LGF40 maintains its shape and properties over time-reducing wear, noise, and maintenance costs.
