Remark

The blue part is the flow phase TPU, which provides excellent mechanical properties.

The green part is silicone rubber particles provides silky skin-friendly touch, high and low-temperature resistance, weather resistance, stain resistance, etc.

The black part is a special compatible material, which improves the compatibility of TPU and silicone rubber, combines the excellent properties of the two, and overcomes the shortcomings of a single material.
