TPU-LCF50 | 50% Long Carbon Fiber Reinforced Thermoplastic Polyurethane

TPU-LCF50 is a high performance, ultra-reinforced thermoplastic elastomer incorporating 50% long carbon fiber, engineered for extreme mechanical loads, precision dimensional stability, and demanding structural flex applications. This formulation represents a new tier of semi-rigid composite performance—approaching the mechanical strength of metals—while preserving core TPU benefits such as impact resistance, fatigue durability, and chemical resilience.

Compared to TPU-LCF40, this 50% formulation delivers superior stiffness, improved tensile strength, and greater thermal resistance, enabling its use in load bearing, high cycle environments. The long fiber architecture ensures directional strength and enhanced fatigue resistance, making it a viable lightweight replacement for metals or high glass fiber composites in many dynamic structural contexts.

TPU-LCF50 is optimized for automotive, robotics, aerospace support systems, and industrial grade components where high strength, motion control, and shock mitigation are all required in one material.
