TPU for 3D printing: multi-hardness and high-temperature resistance
Aromatic polyether TPU for pellet-extrusion 3D printing across 75A–85D — multiple hardnesses, high temperature resistance, low gel content and dimensional stability.
TPU in additive manufacturing
In 3D printing, material breakthroughs drive the industry's upward spiral. Nilun's pellet-extrusion printing grade is an aromatic polyether TPU spanning 75A–85D, engineered specifically for additive manufacturing.
Product advantages
- Multiple hardness, temperature, clarity and colour options for different customer needs.
- Excellent extrusion processability.
- Low gel content — good surface appearance.
- Dimensional stability and suitability across temperature ranges, with high-temperature resistance a particular strength.
Processing advantages
- No material build-up — the substrate resists build-up during processing, keeping equipment running with less cleaning.
- Easy extrusion — good flow for filament-extrusion lines, keeping production continuous.
- Consistent extrusion quality — formulation keeps filament dimension and appearance stable, raising yield.
Wide temperature adaptability
Printed parts hold their shape across high and low temperatures without deformation — especially suited to customised, large-format display artwork and other large-scale prints.
