Toluene Diisocyanate (TDI)

Toluene Diisocyanate (TDI)

Category:

Isocyanate / Polyurethane Raw Material / Industrial Chemical

Description:

Toluene Diisocyanate (TDI) is a highly reactive aromatic diisocyanate used as a key raw material in polyurethane (PU) foams, elastomers, coatings, adhesives, and sealants. It appears as a clear to pale-yellow liquid with a pungent odor and is valued for its excellent reactivity and flexibility in formulation. TDI is essential in both flexible foam and CASE (Coatings, Adhesives, Sealants & Elastomers) applications across furniture, automotive, and insulation industries.

Applications:

• Flexible polyurethane foam (furniture, bedding, automotive seats)
• Rigid & semi-rigid PU foam systems
• Coatings and industrial finishes
• Adhesives & sealants
• Elastomers for wheels, rollers, and molded parts
• Foam insulation materials
• Textile and leather finishing chemicals

Technical Details:

• Chemical Formula: C₉H₆N₂O₂
• CAS Number: 26471-62-5
• Appearance: Clear to pale yellow liquid
• Odor: Sharp, pungent
• Density: ~1.22 g/cm³
• Flash Point: ~127°C
• Solubility: Reacts with water; soluble in organics

Packaging:

• 250 kg drums
• ISO tanks / bulk tankers
• IBC containers (on request)

Storage & Handling:

• Store in tightly sealed containers in a cool, dry, ventilated area
• Protect from moisture — reacts to release CO₂ and cause pressure buildup
• Use proper PPE: gloves, goggles, face shield, chemical-resistant clothing
• Provide exhaust ventilation when handling
• Avoid inhalation and direct contact
• Keep away from heat, flames, and incompatible chemicals
• Follow all regulatory and safety guidelines for handling isocyanates
