1. Flexible Polyurethane Foams

Main application of TDI.

Used in the manufacture of furniture, bedding, automotive seats, and packaging foams.

Offers excellent cushioning, softness, and resilience.

2. Coatings, Adhesives, Sealants, and Elastomers (CASE)

Used in polyurethane coatings for wood, metals, and plastics.

Applied in adhesives and sealants requiring toughness, flexibility, and strong bonding.

TDI-based elastomers are used in wheels, rollers, and various mechanical components.

3. Rigid Foams (Limited Use)

Sometimes used in blends with other diisocyanates for rigid foam insulation and construction materials.

4. Binders and Encapsulants

Employed in foundry binders, textile coatings, and electronic encapsulants.

High Reactivity: Reacts quickly with polyols and water, allowing efficient foam production.

Versatile: Suitable for a wide range of polyurethane applications.

Adjustable Properties: Final polymer properties can be tuned via formulation and processing.

Excellent Mechanical Properties: Contributes to the strength, elasticity, and durability of polyurethane products.

Cost-Effective: More economical compared to some aliphatic diisocyanates for flexible foam production.

Tolylene-2,4-diisocyanate (TDI, CAS 584-84-9) is a core raw material for polyurethane production, especially flexible foams used in consumer and industrial applications. Its high reactivity, versatility, and economic value make it a widely used diisocyanate, though it requires careful handling due to its toxic and sensitizing nature. TDI continues to be essential in furniture, automotive, packaging, and coating industries.
