| Grade · open for datasheet | Best for | Yield MPa | Tensile MPa | Elong. % | Hardness |
|---|---|---|---|---|---|
E-TPA | Specify the expanded bead foam at 0.18 density for ultralight running midsoles and impact cushioning, where rebound typically exceeds E-TPU; modulus is only 0.004 GPa. | — | 2 | 130 | 40 Shore A |

HP TPAThis page HP 3D High Reusability TPA (enabled by Evonik) · MJF powder | A lightweight flexible polyamide elastomer with high rebound and uniform properties for resilient production parts. | — | 10 | 250 | 91 Shore A |
Shore D 55 | Use the medium Shore D 55 level for structural elastic parts, ski boot liners and gear or coupling dampers that need 48 MPa tensile with 500 % elongation. | 15 | 48 | 500 | 55 Shore D |
Bio-based PEBA | Choose the bio-based version built on a castor-oil PA11 hard block for sustainable footwear and consumer goods; renewable carbon is high and mechanicals match standard Shore D 55 material. | 16 | 45 | 500 | 55 Shore D |
UNFDefault Unfilled / Natural | Use the unfilled natural grade as the default for injection molding and extrusion — Shore D 60 with 52 MPa tensile and 430 % elongation suits shoe midsoles, functional parts and tubing. | 20 | 52 | 430 | 60 Shore D |
Shore D 63 | Choose the stiff Shore D 63 level, 0.29 GPa modulus and 24 MPa yield, for high-stiffness resilient sheet and plates and sporting-goods spring elements; elongation drops to 400 %. | 24 | 55 | 400 | 63 Shore D |
Heat-stabilized grade | Use the heat-stabilized grade with its reinforced antioxidant package to improve retention of the polyether soft segment under long-term ageing at 80–100 °C, with service to 95 °C. | 24 | 52 | 360 | 63 Shore D |
Shore D 72 | Pick the hardest standard level — Shore D 72, 0.51 GPa modulus, 58 MPa tensile — for racing-shoe carbon-plate liners and high-stiffness elastic hinges; elongation is reduced to 350 %. | 31 | 58 | 350 | 72 Shore D |
Shore D 25 | Pick the softest level, Shore D 25 (≈75–80 Shore A) with 750 % elongation and 0.017 GPa modulus, for high-rebound cushioning, catheter soft tips and flexible films; service temp falls to 65 °C. | — | 34 | 750 | 25 Shore D |
Shore D 35 | Choose Shore D 35 for soft extrusion and blown film — medical tubing, breathable membranes and soft grips — where 700 % elongation matters more than the 70 °C temperature limit. | — | 38 | 700 | 35 Shore D |
Transparent / clear PEBA grade | Use the clear grade for sports eyewear nose pads, transparent upper components and soft-touch transparent overmolding at Shore D 40, 40 MPa tensile and 500 % elongation. | — | 40 | 500 | 40 Shore D |
Shore D 40 | Pick Shore D 40 when rebound and flexibility must be balanced, as in running midsoles, air-retention bladders and hoses; it gives 45 MPa tensile with 640 % elongation. | — | 45 | 640 | 40 Shore D |

Choosing 3D High Reusability TPA (enabled by Evonik)
A lightweight HP MJF thermoplastic polyamide elastomer for resilient parts that need rebound and uniformity rather than rigid-nylon behavior.
- Consider it for
- Robotic grippers and compliant mechanisms · Winter-sports and automotive-interior components · Flexible fluid-system parts after media testing
- Tradeoffs
- TPA is a distinct polyamide elastomer and should not be treated as a generic TPU. HP lists it for the discontinued Jet Fusion 4200 family, so current production availability must be confirmed.
- Design and validation
- Validate wall or lattice geometry, rebound, compression set and the weak build direction under the actual cycling load. Confirm that the 4200 process route remains available before design freeze.
- Finishing
- White is the cataloged as-printed colour and the row is not offered as dyeable. Flexible coatings or cleaning steps must be tested for cracking, friction and media compatibility.
- Before choosing
- Is TPA rebound the real need, or is an MJF TPU hardness grade easier to source? Is a qualified Jet Fusion 4200 production route available?
