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:
- 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 that 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
