Applications of TPU Air HR 80A
Midsoles
Insoles
Slides/Slippers
Comfort Liners

High-Rebound Resilience
Specificallytunedforfootwear,itoffers48%β50%resilience,providinga"bounce"thatoutperformsstandardfilaments.

Ultralight Active Foaming
Achieve a 50% weight reduction. Create "air-infused" structures that feel weightless without losing structural integrity.

Controllable Hardness (64Aβ80A)
Control the "squish" via temperature. Dial in softer zones for the heel and firmer support for the arch in one print.
Premium Fabric-Like Texture
No more "cheap plastic" feel. The foamed surface provides a high-end, production-ready textile finish.

Shock Absorption & Anti-Flattening
Absorbs heel-strike impact while maintaining its shape over timeβavoiding the "flattening" common in cheap foams.

Universal Compatibility οΌ Rock-Solid Reliability
Extensively verified for both enclosed and open-frame FDM printers, ensuring stable, hassle-free extrusion and repeatable results for every project
