Toluene diisocyanate (TDI) is a chemical compound commonly used in the production of flexible polyurethane foams. It is primarily derived from toluene, a solvent found in many industrial applications. TDI is known for its ability to react with polyols to create foams used in furniture, mattresses, and automotive seating. Due to its reactive nature, TDI can pose health risks if proper safety measures are not followed. Exposure may lead to respiratory issues and skin irritation. Therefore, industries that utilize TDI must adhere to strict regulations and safety protocols to protect workers and the environment.
