40% Long Glass Fiber Reinforced TPU (LFT-TPU-LGF40-NG04M)
This is where strength meets flexibility. Our LFT-G®TPU LGF40 NG04M is an advanced structural composite that 40% long glass fiber filled Thermoplastic Polyurethane(TPU) elastomer, engineered to absorb extreme impacts and dampen vibration without failure. By reinforcing a durable, polyester-based TPU matrix with 40% long glass fibers, we have created a unique material that offers a compelling alternative to die-cast metals and brittle plastics in high-stress, dynamic applications. In short, this page details a unique engineering solution (LFT-TPU-LGF40-NG04M) - blending the structural strength of 40% long fiber with the exceptional toughness and energy absorption of TPU for demanding auto parts, sporting goods, and industrial dampers.
People Also Ask:
What is TPU GF40?
It is a thermoplastic polyurethane reinforced with 40% glass fiber. Our long-fiber grade creates a semi-rigid material with exceptional toughness, ideal for structural auto parts, durable sport parts, and energy-absorbing components like a gun recoil panel.
What is long fiber TPU used for?
It is used for parts that require a unique combination of strength, flexibility, and extreme impact resistance. Applications include automotive suspension components, power tool housings, and protective gear where vibration damping and durability are key.
Is reinforced TPU strong?
Yes, very. By reinforcing TPU with long glass fibers, we dramatically increase its strength, stiffness, and creep resistance, transforming it from a soft elastomer into a robust, load-bearing structural composite.
Visualizing Durability: Impact Energy Dissipation
Rigid Plastic (e.g., standard PA66)
Transfers shock and is prone to brittle failure. The impact energy is not absorbed effectively, leading to cracks.
LFT-G® TPU LGF40
Absorbs and dissipates impact energy while maintaining structural integrity. The ideal balance of strength and resilience.
Unfilled TPU
Absorbs energy but deforms excessively and lacks the strength to be used in structural, load-bearing parts.
Case Study: Firearm Recoil Pad
The Challenge
A manufacturer of high-end sporting rifles needed to develop a new recoil pad for their flagship product. The goal was to significantly reduce the "felt recoil" for the shooter, enhancing comfort and accuracy. The material needed to be exceptionally tough to absorb the violent, instantaneous shock of firing, yet stiff enough to provide a stable, non-mushy interface with the shoulder. It also needed to be resistant to gun oils and cleaning chemicals, and maintain its performance in both hot and cold weather.
The Solution: LFT-TPU-LGF40-NG04M
Our LFT-TPU composite was the perfect material for this demanding application. The inherent damping properties of the TPU matrix absorbed and dissipated the recoil energy, while the 40% long glass fiber network provided the structural reinforcement needed for a solid, responsive feel. The material's "No Break" impact strength ensured it could withstand thousands of firing cycles without cracking or degrading. Its polyester base provided excellent resistance to common firearm chemicals.
Result: A recoil pad that reduced measured felt recoil by over 30% compared to the previous rubber design, while also being lighter and more durable, leading to a significant improvement in shooter experience and product reviews.
