弹性
TPU材料的弹性恢复能力比PETG材料高20%左右,屈服强度和屈服应变率均显著高于PETG材料,弹性工作范围更宽,能承受更大的弹性变形。变形后的回弹性能明显高于PETG材料,具有优异的形状记忆性能。
撕裂强度
与PETG材料相比,TPU材料的抗撕裂性提高了约20%。分子链上的N-C和C-N键可以增强分子链的强度,并能有效抵抗微观裂纹的产生和扩展,使材料表面在应力和变形下不会出现银纹。在实验中,抗疲劳性和抗撕裂性都得到了提高。
压力测试
TPU材料的抗弛豫衰减性能提高了约30%,且应力弛豫稳定后的残余应力明显高于PETG材料。在正畸周期提供更多的正畸能量。提供了更多的
连续有效的受力,提高了齿移动的精确控制和放置率,降低了重启率。
Through objective data comparison, it is found that the elastic recovery ability of Brealigner material is greatly improved than that of PETG, and it can rebound significantly after deformation; the anti-relaxation attenuation performance is significantly higher than that of PETG material, which can provide more align energy; it has strong tear resistance and rigidity Strong, it is currently the most ideal material for invisible aligners.
