3-Layer TPU Sheet

SmileyNova’s aligner material is made of polyether-based TPU (thermoplastic polyurethane) with 3-layer structure. The sheet features high tensile strength, high modulus, and good biocompatibility, an ideal choice for the production of clear aligner.

The 3-layer solution reaches the balance between the resilience needed for easy insertion and take-off and the rigidity needed for force persistence and durability. Different properties of each layer ensure the ideal force expression required by orthodontic treatment.
