Problems solved by technology

[0003] TPR material is one of the main sole materials, fitness equipment materials and toy materials. It has been developed for decades since 1963. The products are constantly updated, but there are still too high density (generally 0.9-1.2 / cm 3 ), and the surface is rough. The density and wear resistance of TPR are generally solved by adding foaming agents and wear-resistant agents on the market. However, due to the decrease in density, the tearing force and bending resistance of the material will naturally decrease, which cannot be achieved at all. The requirements for use need to be further improved
