AI Overview
Easy flow TPU (Thermoplastic Polyurethane) compounds are specially formulated materials designed to solve the inherent processing difficulties of traditional, sticky, and viscous TPU. They feature lower viscosity and a higher melt index (often exceeding 30 g/10 min at
), allowing them to flow more easily during injection molding or 3D printing.
Key Features and Benefits
- Improved Processability: Enhanced flowability means better filling of complex, intricate, or thin-walled mold cavities.
- Faster Production Cycles: Reduced viscosity enables faster injection speeds and shorter cycle times, boosting productivity.
- High-Speed 3D Printing: In 3D printing, "High Flow" (HF) TPU—such as 95A HF—is designed to handle speeds of 80–100 mm/s or higher, which would cause standard TPU to under-extrude or clog.
- Reduced Processing Defects: Helps eliminate issues like short shots, flash, and part degradation that can occur when trying to force, less-fluid materials through a machine.
- Versatile Compounding: These compounds often blend well with other materials such as PVC, ABS, EPDM, or PC, making them ideal for soft-touch overmolding.

What is the best flow rate for TPU?
What is the best speed for TPU 95A HF printing? Start at 40–60 mm/s for reliable flow and first-layer control, then step up to 70–90 mm/s as your tuning improves. Keep retraction very low (0–1 mm on direct drive, 1–2 mm on Bowden) and reduce acceleration to limit buckling.Oct 7, 2025

What is the disadvantage of TPU?
Disadvantages of TPU
Here are the major reasons why: Finishing difficulty: The surface requires preparation such as cleaning and mild abrading to ensure good adhesion. Solvent-based finishing products might not bond well. In terms of longevity of the finish, flexibility might work against you if the finish is rigid.
