2. Usage

Tolylene-2,4-diisocyanate, also known as TDI, is an organic compound with the chemical formula C9H6N2O2. It is primarily used in the production of polyurethane foams, coatings, adhesives, and elastomers.

TDI is a versatile compound that reacts with polyols to form polyurethane polymers. These polymers have a wide range of applications in various industries. Some common uses of TDI include:

  1. Polyurethane Foams: TDI is a key ingredient in the production of flexible and rigid polyurethane foams. These foams are used in mattresses, furniture, automotive seats, insulation materials, and packaging.
  2. Coatings and Adhesives: TDI is utilized in the formulation of polyurethane coatings and adhesives. These coatings provide excellent protection against corrosion, weathering, and chemical attacks. Polyurethane adhesives have strong bonding properties and are used in various industries, including construction, automotive, and footwear.
  3. Elastomers: TDI is used to produce polyurethane elastomers, which are highly elastic materials. These elastomers find applications in gaskets, seals, tires, rollers, and other mechanical components requiring flexibility and durability.

It is important to note that TDI is a potent respiratory and skin sensitizer. Proper safety precautions must be taken during its handling and usage to ensure worker safety.
