Petrochemicals are chemical products derived from petroleum and natural gas. They are produced through processes like refining and cracking, which break down these fossil fuels into simpler compounds. Common petrochemicals include ethylene, propane, and benzene, which serve as building blocks for various materials. These compounds are essential in creating everyday products, such as plastics, fertilizers, and synthetic fibers. The petrochemical industry plays a significant role in the global economy, providing raw materials for numerous sectors, including automotive, construction, and healthcare.
