What is carbon fiber? Carbon fiber is a kind of new fiber material, in which the carbon content up to 95%. the properties of carbon fibers, such as high stiffness, high tensile strength, low weight, high chemical resistance, high temperature tolerance, high penetration of X-rays, good electromagnetic shielding and low thermal expansion, and the soft machinability of textile fibers, make it very popular as the new generation of reinforcing fiber. So our advantage: 1. Using 3K twill carbon fiber material, lustrous, bright colors, gradient effect, fire resistance, anti-bacterial & anti-radiation, wear resistant, scratch resistant, this carbon fiber belt allows us to be confident and use it for a long time. 2. TPU material: Anti abrasion, environmental protection, oil resistance, yellowing resistance, high & low temperature resistance, high flexibility, which feels smooth and soft to touch. 3. Genuine leather: Soft, exquisite, environmental protection, that can be used for two sides.
