UnverifiedNBR材质回弹和减震优于普通EVA，同厚度下缓冲更好，但密度不足的NBR久用会压塌变薄，选购需关注密度（克重）而非仅看厚度标称73% similarUnverifiedNBR材质密度较低，长期高频踩踏同一区域容易出现凹陷变形，耐久性不如TPE和EVA拼接垫72% similarUnverified材质强度越高（如加厚编织尼龙）安全性越好但网体越硬重、透光性差；轻薄网美观但承受儿童反复推挤易松脱变形66% similarUnverified五层瓦楞硬度高、抗压强度好，但箱体自重也更大且折叠后体积较厚，不方便搬家后收纳复用65% similarUnverified透氧系数越高的材质越安全但镜片越软、易变形破损，护理和摘戴难度增加；青少年操作不熟练时可适当选Dk 90-120的平衡型材质而非盲目追求最高Dk64% similar
