Chemical Name: Toluene Diisocyanate (TDI)
Synonyms: Toluylene Diisocyanate; Methylphenylene Diisocyanate; 2,4-Toluene Diisocyanate (primarily 80/20 mixture with 2,6-isomer)
Molecular Formula: C₉H₆N₂O₂
Molecular Weight: 174.2 g/mol
Description: TDI is a colorless to pale yellow liquid aromatic diisocyanate with a sharp, pungent odor. It is highly reactive and serves as a primary raw material for producing flexible polyurethane foams, offering excellent elasticity, comfort, and durability.
Key Properties:
Applications: TDI is primarily used to produce flexible polyurethane foams, as well as prepolymers for elastomers, adhesives, sealants, and coatings. These products provide superior resilience, load-bearing capacity, comfort, and longevity, making them ideal for:
TDI monomer is highly reactive and highly toxic. It is a known respiratory sensitizer and may cause severe asthma-like symptoms, skin irritation, and eye damage. Strict ventilation, personal protective equipment, and exposure controls are essential during handling.
