There are various factors to affect the hardness of a cable. For TPU cable, most importantly, it has a sheath with hardness from 60A to 80D usually. By changing the compound ratio of TPU sheath, cable with different hardness can be obtained. With the increase of hardness, the cable still maintains good elasticity and wear resistance.
TPU cable has a polyurethane sheath with excellent physical and mechanical properties.
