The Ultimate Strength & Toughness Solver
Engineers frequently struggle with materials that are either too soft, like pure TPU, or too brittle, like standard short-fiber reinforced plastics. LFT-G® TPU-NA-LGF50 completely breaks the traditional trade-off between strength and toughness. By infusing 50% continuous long glass fibers into a premium thermoplastic polyurethane matrix, it forms a robust internal 3D skeletal network during injection molding. This delivers metal-like rigidity while retaining the exceptional impact-absorbing flexibility and abrasion resistance inherent to TPU.

Processing Guidelines for TPU LGF Resin
Pre-drying
80–100°C / 4–6h
Critical for TPU Matrix
Injection
Melt Temp: 220–260°C
Low Shear Processing
Tooling Settings
Mold Temp: 45–70°C
Large Gate Design
Engineered for Extreme Wear & Impact Resistance
Premium Safety Footwear Toe Caps
Standard steel toe caps are uncomfortably heavy and conduct freezing temperatures. Our TPU LGF50 provides identical crush protection with a 50 kJ/m² impact rating, drastically lightening the boot while offering superior insulation and rebound characteristics for workers in brutal environments.
Heavy Machinery Gears & Bearings
Industrial transmission components face constant frictional wear and extreme torque. The internal glass fiber skeleton minimizes anisotropic shrinkage (maintaining precise gear tooth geometry), while the TPU matrix acts as a permanent shock absorber, heavily reducing operational noise and eliminating premature cracking.
Alpine Winter Sports Equipment
Traditional plastics become dangerously brittle in sub-zero alpine conditions. TPU LGF50 retains its unparalleled flexibility and shatter resistance even in extreme cold, allowing manufacturers to create ultra-rigid yet highly responsive professional ski boots and snowboard bindings.
