A synthetic plastic material derived from benzene. Nylon can be used to form fibres, filaments, bristles, or sheets to be manufactured into yarn, fabric, and cordage; and it can be formed into moulded products. Nylon is tough, elastic and strong, and it has high resistance to wear, heat, and chemicals. It is generally known in the form of fine filaments in such articles as hosiery and sports equipment, e.g. parachutes; but its applications also include engineering plastics for cars, toys, healthcare products, carpets, roller-blade wheels, ship sails and parachutes.
