Used primarily as a cross-linking agent in polymer chemistry, it enhances the durability and stability of various materials. In the production of polyurethanes, it improves elasticity and resistance to wear, making it valuable for coatings, adhesives, and sealants. Additionally, it serves as a key component in the synthesis of sulfur-containing polymers, which are utilized in specialized applications like fuel cell membranes due to their proton conductivity. Its ability to form strong chemical bonds also makes it suitable for use in high-performance elastomers and composites.
