Nylon is a synthetic polymer made from raw materials derived from petroleum, natural gas, or coal. These materials are processed into adipic acid and hexamethylene diamine, which undergo a condensation reaction to form nylon. The resulting polymer is extruded and drawn to create fibers or sheets. Nylon is widely used in industries ranging from textiles to automotive parts due to its strength, durability, and versatility.
