Used as a key intermediate in the production of polyurethanes, BDO is essential in manufacturing flexible and rigid foams found in furniture, automotive seats, and insulation materials. It serves as a precursor for tetrahydrofuran (THF), which is widely used in the synthesis of polymers like polytetramethylene ether glycol (PTMEG), a component in spandex fibers and elastane. BDO is also employed in the formulation of plasticizers to improve the flexibility and durability of plastics, especially in PVC applications. In the electronics industry, it is used as a solvent and in the production of printed circuit boards due to its ability to dissolve a wide range of organic compounds. Additionally, BDO finds use in the manufacture of biodegradable polyesters and coatings, contributing to environmentally friendly materials.
