TDI 80/20 – Toluene Diisocyanate

TDI 80/20 is a liquid aromatic isocyanate composed of 80% 2,4-Toluene Diisocyanate and 20% 2,6-Toluene Diisocyanate. It appears as a clear to pale yellow liquid with a pungent odor and is known for its high reactivity. TDI 80/20 is a key raw material in the formulation of flexible polyurethane foams and non-foam urethane systems.

Primary Applications:

This versatile isocyanate is used with polyols to produce:

• Flexible polyurethane foams
• High-resilience and high-load foams
• Semi-rigid ester-based foams
• Molding foams
• Elastomers and synthetic leather

End-Use Industries:

• TDI 80/20 plays an important role in the production of:
• Mattresses and upholstered furniture
• Footwear and shoe soles
• Adhesives, coatings, and hardeners
• Lubricant additives
• Industrial paints and protective coatings used in automotive, aerospace, and rail applications

Safe Handling & Storage:

• Store in a dry and ventilated location which is safe from fire in a strongly sealed container
• Avoid contact with moisture, heat sources, or open flames
• Use safety equipment like eye protection, gloves, and aprons
• Open containers carefully, allowing internal pressure to stabilize before fully opening

Emergency Measures:

• Inhalation: Move the affected person to fresh air and seek medical attention; oxygen may be required
• Skin Contact: Remove contaminated clothes and wash skin with soap and water
• Eye Contact: Rinse eyes thoroughly with clean water for at least 15 minutes
• Ingestion: Do not induce vomiting; drink water and get immediate medical help
