The appearance of the data cable is also the most intuitive part. The outer layer of the data cable on the market is generally divided into two materials: PVC and TPE: PVC is ordinary plastic, which is cheap, mostly used in small workshops, and harmful to the environment; TPE is a kind of rubber It is a new material with high elasticity, high strength, and plastic injection molding characteristics. The data cable made of TPE is durable, smooth to the touch, safe and non-toxic, and will not cause any irritation to human skin. Nowadays, most of the international first-line brands use TPE as the outer material of the data cable. When selecting the data cable, generally try to choose a data cable with a thick wire diameter and a non-reflective surface of the wire. The thicker the wire, the higher the tensile strength. It has a good protective effect; the less reflective the surface of the wire, the higher the TPE content in the wire, the data wire has good elasticity, anti-aging, and is no
