TPU Air is a lightweight elastomer system whose finished density and apparent hardness can be tailored from a denser 92A-like response to a light, foam-like 55A response. It is suited to cushioning, damping and ergonomic interfaces where mass and compliance matter.
Material family names are not specifications. This page anchors the discussion to a named commercial grade and published printed-specimen data, then translates that data into practical selection and design guidance.
TPU Air is a lightweight elastomer system whose finished density and apparent hardness can be tailored from a denser 92A-like response to a light, foam-like 55A response. It is suited to cushioning, damping and ergonomic interfaces where mass and compliance matter.
Choose TPU Air for low-density cushioning and tunable compliance—not for untested structural loads.
Orientation, conditioning and geometry can move finished-part performance materially. Use these figures to compare candidate materials—not as guaranteed minimums.
| Property | Representative value | Test / context |
|---|---|---|
| Representative finished density | 0.7–0.9 g/cm³ | Application-dependent |
| Dense-state hardness | ≈92A | Manufacturer reference |
| Low-density hardness | ≈55A | Manufacturer reference |
| Potential weight saving | Up to ≈50% | Compared with dense TPU |
| Relative volume increase | ≈1.4–1.6× | Manufacturer reference |
| Mechanical allowables | Application testing required | Geometry and density dependent |
XY values normally represent flat-printed specimens. Z-direction strength can be substantially lower. Final production settings should be qualified on representative geometry.
A useful material choice starts with load case, temperature, environment, duty cycle and failure consequence—not the strongest number on a datasheet.
