Polyurethanes are synthetic polymers formed from the reaction of polyols and isocyanates, offering a broad range of properties tunable from rigid to flexible formulations. They are widely used across industries including automotive (seals, cushioning, structural components), construction (insulation, roofing, sealants), footwear, furniture, and elastomeric applications where a balance of mechanical strength, flexibility, and chemical resistance is required. Engineers select polyurethanes when conventional plastics or rubbers cannot meet combined demands for durability, impact absorption, and processing versatility—particularly in applications involving thermal cycling or exposure to oils and solvents.
