In the petrochemical industry, the key advantage of polymer materials lies in their exceptional corrosion resistance, enabling them to withstand acids, alkalis, salts, and various hydrocarbon solvents over long periods, significantly extending the service life of pipelines, storage tanks, and reactor linings. Their light weight, high strength, wear resistance, and insulation properties make them ideal for conveying pipelines, sealing elements, and cable sheathing, playing a critical role in enhancing equipment safety, reliability, and reducing maintenance costs.
