How to distinguish PETG and TPU sheet?
Under the same folding force, PETG film is easier to form creases, and the rebound effect is poor. General materials lack elasticity.
Soft-hard-soft model TPU sheet advantage
Excellent comfort during tooth movement stages
Durability and crack resistance for long-term retainer use
Long-duration tooth-moving force
Ease of Insertion & removal
-Compared with traditional PETG, material of TPU manifests superior performance in several aspects such as wearing comfortability, tensile strength, durability, and stress retention ratio, etc.
-ExcellentThermal forming function passed through the test with international GB10004-88 standard ASTMG955 method; Excellent Tenicity function,passed through the test with international GB10004-88 standard ASTMD638 method, single tensile test with good resilient no breakage
