Nylon
A synthetic fiber made from crude oil and natural gas that often is used in conductor jacketing material. This plastic has great toughness, strength and elasticity, high melting point and good resistance to water and to most chemicals. Its abrasion resistance is superior to polythene and PVC, and because of this it is often used as a sheathing material on previously jacketed polythene or PVC cables or wires, and is simple to apply to wire or cable.
