TPR material has good elongation and resilience. TPR material is environmentally friendly polymer material, odorless. TPR is free of heavy metals, EN71, ROHS, plasticizers (phthalate plasticizers) and SVHC substances. The wear resistance of TPR material is not as good as that of TPU, but TPR has a better silence effect. The TPR sole is odorless, and the surface of the TPR sole is relatively smooth and traceless. TPR soles are soft, often used on baby shoes, and can be folded repeatedly. TPR soles are widely used in baby shoes and shoes for the elderly, which are softer and more comfortable. Moreover, TPR material soles are also relatively environmentally friendly and can be recycled.
