TOLUENE DIISOCYANATE Chemical compatibility with O-rings, rubbers, & plastics

Toluene diisocyanate (TDI) is a colorless to pale yellow liquid with the chemical formula C9H6N2O2, used primarily as a raw material in the production of polyurethane foams, coatings, adhesives, and elastomers. It is employed in various industrial and chemical applications, including the manufacturing of flexible and rigid foams, sealants, and insulation materials. Proper handling and storage of toluene diisocyanate are essential to maintain its quality and prevent accidents, as it is highly toxic and can pose severe health risks if inhaled, ingested, or absorbed through the skin. Safety measures, including the use of appropriate protective equipment and adherence to handling protocols, are crucial when working with toluene diisocyanate. Its effectiveness as a raw material and its unique properties make toluene diisocyanate a valuable chemical in numerous industrial and chemical applications, contributing to the production of a wide range of polyurethane-based products and materials.
