50% Long Glass Fiber Reinforced TPU (LFT-TPU-LGF50-NG05M)
This is where structural strength meets an elastomeric soul. LFT-TPU-LGF50-NG05M is our premier structural elastomer, engineered to provide metal-like stiffness while delivering the unparalleled vibration damping and impact absorption that only a TPU composite can offer. With a 50% long glass fiber reinforcement in a durable polyester TPU matrix, it is the ultimate solution for lightweighting metal parts in high-vibration environments. In short, this page details a unique "structural elastomer" (LFT-TPU-LGF50-NG05M) - blending the high stiffness of 50% long fiber with the exceptional energy absorption and damping properties of TPU for demanding auto parts, sporting goods, and industrial noise reduction components.
People Also Ask:
What is TPU GF50?
It is a high-stiffness thermoplastic polyurethane reinforced with 50% glass fiber. Our long-fiber grade creates a robust composite with excellent vibration damping, making it ideal for structural auto parts and heavy-duty sport parts.
Can TPU be used for structural parts?
Absolutely. By reinforcing TPU with a high loading of long glass fibers, we transform it into a structural composite capable of replacing metal. It carries significant loads while also absorbing impact and vibration in a way that rigid plastics cannot.
How does reinforced TPU compare to aluminum?
It offers a similar strength-to-weight ratio but with two major advantages: up to 70% lighter weight and vastly superior vibration/noise damping. This makes it a smarter choice for applications where weight and user experience (NVH) are critical.
Beyond Strength: The NVH Advantage Over Metal
Die-Cast Aluminum
High stiffness but low damping. It transmits vibrations and resonates, creating unwanted noise and harshness (NVH).
LFT-TPU-LGF50-NG05M
High stiffness AND inherent damping. It absorbs and dissipates vibrational energy, resulting in quieter, smoother, and more reliable components.
Case Study: High-End Automotive Camera Mount
The Challenge
A luxury automaker was developing an advanced driver-assistance system (ADAS) with a forward-facing camera mounted behind the rearview mirror. The camera mounting bracket was a critical component. It needed to be extremely stiff to prevent image shake ("jello" effect) from road vibrations, which could compromise the ADAS functionality. The previous machined aluminum bracket was stiff but transmitted too much high-frequency vibration and was costly.
The Solution: LFT-TPU-LGF50-NG05M
Our LFT-TPU composite provided a unique solution that aluminum could not. The 50% long glass fiber loading delivered the high modulus required to create a rock-solid mounting platform, eliminating low-frequency shake. At the same time, the inherent damping properties of the TPU matrix absorbed high-frequency road buzz, resulting in a clearer, more stable video feed than even the aluminum bracket could provide. The single-shot molding process also drastically reduced cost and complexity.
Result: A lighter camera bracket that improved video stability by 40%, passed all automotive durability tests, and reduced part cost by 55%.

Application Spotlights: Solving Structural Challenges
Automotive Powertrain Mounts
The Problem: Traditional engine mounts use a complex assembly of a cast metal bracket and a separate rubber damper, which is heavy, costly, and a point of failure.
The Solution: A single, injection-molded LFT-TPU-LGF50 part that acts as both the structural bracket and the damping element.
The Result: Dramatically reduced NVH, longer fatigue life, part consolidation, and over 60% weight savings.
High-Performance Sporting Goods
The Problem: Athletes need equipment (like bicycle frames or ski components) to be stiff and responsive for power transfer, but also need it to absorb vibrations and impacts from rough terrain to reduce fatigue and improve control.
The Solution: LFT-TPU-LGF50 allows for the design of frames and components that are rigid where needed, but have inherent damping properties that a carbon fiber or aluminum frame lacks.
The Result: A more comfortable, less fatiguing user experience, with improved control and "bombproof" durability against impacts that would damage other materials.
