Xiamen LFT Thermoplastic Polyurethane TPU Long Glass Fiber filling composite industry product

What is TPU?

TPU (Thermoplastic Polyurethane) is a high-performance elastomer formed by the reaction of diisocyanates (MDI/TDI), polyols, and chain extenders. It combines the elasticity of rubber with the processing advantages of thermoplastics.

TPU features a unique molecular structure consisting of rigid segments and flexible soft segments, giving it excellent balance of strength, flexibility, and durability.

Main Advantages

• High tensile strength and elasticity
• Excellent wear and abrasion resistance
• Outstanding low-temperature flexibility
• Oil, water, and aging resistance
• Good environmental and UV resistance

What is TPU-LGF?

TPU-LGF (Long Glass Fiber Reinforced TPU) is a modified composite material that combines TPU with long glass fibers (LGF 20%–60%). It significantly enhances mechanical strength, stiffness, and dimensional stability while maintaining TPU flexibility.

Key Benefits of TPU-LGF

• High impact strength with improved rigidity
• Excellent fatigue and load-bearing performance
• Good dimensional stability under stress
• Enhanced creep resistance
• Balanced toughness and structural strength

Application Fields

TPU-LGF is widely used in industrial and engineering components requiring both flexibility and strength:

• Safety toe caps and protective equipment
• Power tools and pneumatic nail gun housings
• Mechanical structural parts and guides
• Automotive components (doors, windows, interior parts)
• Nuts, bolts, and industrial fasteners

Product Appearance

TPU-LGF is typically supplied as white or natural cylindrical pellets. Color and fiber length can be customized according to customer requirements.

Product Specification

FAQ

1. Are special injection molding requirements needed for LGF materials?
Yes. Screw design, mold structure, and processing parameters must be optimized for long fiber reinforcement.

2. When can long fiber replace short fiber?
When higher mechanical performance or metal replacement is required, long fiber composites provide significant advantages over short fiber materials.
