The material selection of yoga mats should be based on personal needs, practice intensity, environmental protection needs, portability and economy. The following are the characteristics of several common yoga mat materials:

TPE material: environmentally friendly, good anti-slip, good elasticity, lightweight, but relatively expensive, and average wear resistance. Suitable for practitioners who pursue environmental protection, portability and comfort.
PVC material: affordable, durable, good anti-slip performance, but poor environmental protection, and may be stiff to the touch. Suitable for beginners and those with limited budgets.
Natural rubber material: environmentally friendly, good anti-slip, high comfort, and strong durability. Suitable for practitioners who use it frequently and pursue comfort.
NBR material: good wear resistance, but poor anti-slip, and relatively cheap. More suitable for fitness use, not suitable as a yoga mat.
In summary, when choosing the material of a yoga mat, you should consider your own needs and budget and choose the yoga mat that suits you best.
