What is TPU?
TPU (Thermoplastic Polyurethane) is a polyurethane-based elastomer known for its excellent abrasion resistance, high elasticity, and durability. It’s widely used in industrial applications where mechanical wear is a concern.
TPU의 주요 특성
- Shore Hardness: 60A to 95A
- 인장 강도: 25-50 MPa
- Elongation at Break: 400-700%
- Abrasion Resistance: 우수
- 내화학성: Good resistance to oils, greases, many solvents
- Temperature Range: -40°C to +80°C
Common TPU Applications
- Industrial seals and gaskets
- Phone cases and protective covers
- Caster wheels and rollers
- Medical tubing and catheters
- Automotive cable jackets
- Vibration dampening mounts
What is TPE?
TPE (Thermoplastic Elastomer) is a broader category of elastomers combining rubber-like elasticity with plastic-like processability. TPE filaments are typically SBS or SEBS based.
Key Properties of TPE
- Shore Hardness: 30A to 90A
- 인장 강도: 10-30 MPa
- Elongation at Break: 300-800%
- Abrasion Resistance: 보통
- 내화학성: 보통
- Temperature Range: -40°C to +60°C

Printing TPU: Best Practices
Recommended Settings
- 노즐 온도: 220-250°C
- 침대 온도: 50-60°C
- 인쇄 속도: 15-35 mm/s
- Retraction: 1-2mm at 20-25mm/s
- 냉각 팬: 30-70%
Critical Tips
- Use a direct drive extruder for best results
- Dry filament at 80°C for 4-6 hours before printing
- Print slowly to avoid filament buckling
- Reduce retraction to prevent clogs
- Use 0.5mm+ nozzle for easier extrusion
Printing TPE: Best Practices
Recommended Settings
- 노즐 온도: 200-230°C
- 침대 온도: 40-50°C
- 인쇄 속도: 20-40 mm/s
- Retraction: 0.5-2mm at 15-25mm/s
When to Choose TPU
Select TPU when your application requires:
- High wear resistance — gears, rollers, wheels
- Chemical exposure — seals in automotive/industrial environments
- Long-term durability — parts that must last years
- Higher operating temperatures — above 60°C
When to Choose TPE
Select TPE when your application requires:
- Very soft feel — Shore hardness below 70A
- Cost sensitivity — TPE is typically cheaper
- Simple prototypes — quick rubber-like parts
- Low mechanical stress — decorative or soft-touch items
