TPU — Thermoplastic Polyurethane
TPU is an elastic engineering plastic with high abrasion resistance, good tear strength and high flexibility.
What is TPU?
TPU is an elastic engineering plastic with high abrasion resistance, good tear strength and high flexibility.
Typical properties
| Density | ~1.10–1.25 g/cm³ |
| Tensile strength | ~20–60 MPa |
| Shore hardness | typically 60A–75D |
| Abrasion resistance | very high |
Typical applications
TubesCable sheathingRollersSealsShoe solesFilmsTechnical elastomer parts
Industries
FootwearAutomotiveMechanical engineeringCable industrySporting goodsMedical technology
Processing
Injection moulding, extrusion, blow moulding and film extrusion. TPU is moisture-sensitive and must be dried before processing.
