TPU-LCF50 Material Overview
TPU-LCF50 (Thermoplastic Polyurethane with 50% Carbon Fiber) is an advanced, ultra-high-performance material that sets a new benchmark in strength, stiffness, and durability. By combining the inherent flexibility and toughness of TPU with a 50% carbon fiber reinforcement, TPU LCF50 delivers exceptional mechanical, thermal, and wear-resistant properties, making it the ultimate solution for the most demanding applications requiring maximum strength, dimensional stability, and long-term reliability.
Mechanical Performance
With 50% carbon fiber content, TPU LCF50 exhibits superior mechanical characteristics, making it perfect for high-stress and load-bearing applications where stiffness and strength are critical.
- Tensile Strength: ≥ 130 MPa
- Flexural Strength: ≥ 300 MPa
- Impact Strength: ≥ 80 kJ/m²
The increased carbon fiber content maximizes stiffness, strength, and load-bearing capacity, enabling TPU LCF50 to handle extreme mechanical stresses.
Thermal and Chemical Resistance
TPU LCF50 is engineered for extreme thermal environments, offering excellent thermal stability and chemical resistance suitable for harsh industrial and high-temperature applications.
- Heat Deflection Temperature (HDT): Approx. 200°C
- Long-Term Service Temperature: Up to 170°C
- Chemical Resistance: Outstanding resistance to oils, solvents, aggressive chemicals, acids, and alkalis
Wear Resistance and Processing Characteristics
The higher carbon fiber reinforcement in TPU LCF50 provides exceptional wear resistance, ideal for components subjected to constant friction, abrasive conditions, or repetitive motion.
- Wear Resistance: Excellent performance under extreme friction or abrasion conditions.
- Processing Methods: Compatible with injection molding, extrusion, and 3D printing. Higher processing temperatures and optimized settings are required due to the increased fiber load.
Note: The enhanced stiffness from 50% carbon fiber reduces flexibility compared to TPU-LCF40, but greatly improves load-bearing capacity and rigidity.
Environmental Adaptability
TPU LCF50 retains minimal water absorption and excellent dimensional stability, ensuring reliable performance in outdoor or humid environments. Its robust carbon fiber content makes it ideal for structural applications exposed to environmental stressors.
Applications
TPU LCF50 is tailored for the most demanding applications that require extreme strength, rigidity, and wear resistance:
- Automotive Industry: Engine mounts, structural reinforcements, heavy-duty brackets, and high-performance under-hood components.
- Consumer Electronics: Ultra-durable housings, reinforced casings, and load-bearing structural parts.
- Industrial Manufacturing: High-load gears, heavy-duty seals, bushings, and components for high-friction environments.
- Sports and Recreational Equipment: Performance-critical frames, reinforced grips, and high-strength components.
- Aerospace and Defense: Lightweight yet ultra-strong components for extreme environments and high thermal resistance.

Friction coefficient of TPU-LCF
The friction coefficient of TPU is typically between 0.3 and 0.5, while TPU-CF, with added carbon fiber, lowers the friction coefficient to between 0.2 and 0.4. The smaller the value, the better the wear resistance. Therefore, TPU-LCF generally offers better wear resistance than pure TPU, especially under high-load conditions.
