LFT-G TPU Thermoplastic Urethane filled long glass fiber compounds

What is TPU?

TPU (Thermoplastic Polyurethane) is a high-performance elastomer material that combines the elasticity of rubber with the processing advantages of thermoplastics.

TPU is mainly divided into polyester-based and polyether-based types, with a wide hardness range from 60HA to 85HD. It offers excellent:

• Wear resistance
• Oil resistance
• Elasticity and flexibility
• Transparency
• Low-temperature performance
• Environmental friendliness

TPU materials are widely used in consumer products, sports equipment, power tools, automotive parts, cables, and industrial components.

As a thermoplastic elastomer, TPU can be repeatedly heated and processed without significant chemical crosslinking, making it suitable for injection molding and extrusion applications.

Why Reinforce TPU with Long Glass Fiber?

Long glass fiber reinforced TPU composites provide a highly efficient solution when conventional reinforced plastics cannot meet structural performance requirements.

By forming a three-dimensional internal fiber skeleton network, long glass fibers significantly improve:

• Mechanical strength
• Dimensional stability
• Fatigue resistance
• Impact resistance
• Durability in harsh environments
• Metal replacement capability

Compared with Short Glass Fiber

Compared with short glass fiber reinforced materials, long glass fiber composites provide superior load transfer efficiency, better impact resistance, and improved fatigue performance due to the longer retained fiber structure inside the material.

Applications

TPU-LGF materials are widely used in industries requiring flexibility, durability, and structural strength.

• Automotive door and window components
• Safety toe caps
• Mechanical structural parts
• Pneumatic nail gun housings
• Professional power tools
• Industrial connectors and fasteners
• Wear-resistant engineering components
