What Is Toluene Diisocyanate?

Toluene Diisocyanate is an aromatic diisocyanate containing two reactive isocyanate groups. It reacts with polyols to produce polyurethane polymers with different densities, flexibility levels, and mechanical properties.

This reaction forms the basis of many polyurethane products used in everyday and industrial applications. Depending on the formulation, manufacturers can produce soft foam, high-density cushioning, molded parts, coatings, adhesives, and elastomers.

Among different polyurethane raw materials, TDI is especially important in flexible foam production. Its fast reaction speed and efficient processing characteristics help manufacturers achieve consistent production results while maintaining comfort, durability, and resilience in the final product.

Main Toluene Diisocyanate (TDI) Grades

TDI 80/20

TDI 80/20 contains approximately 80% of the 2,4-isomer and 20% of the 2,6-isomer. It is the most common commercial grade and is widely used in flexible polyurethane foam production.

Its main advantages include:

• Excellent foam expansion
• High resilience
• Stable processing performance
• Fast reaction speed
• Consistent foam quality
• Good flexibility
• Efficient production performance

Typical applications include mattresses, pillows, sofa cushions, upholstered furniture, office chairs, automotive seats, and other comfort products.

TDI 65/35

TDI 65/35 contains a higher proportion of the 2,6-isomer. It offers different reaction characteristics and is generally used in more specialized foam systems, molded products, and certain industrial polyurethane applications.

The choice between TDI 80/20 and TDI 65/35 depends on the production method, target density, reaction profile, and required performance of the finished product.

Applications of TDI

Flexible Polyurethane Foam

The largest application of Toluene Diisocyanate (TDI) is the production of flexible polyurethane foam. This type of foam is widely used because it is lightweight, resilient, comfortable, and durable.

Common products include:

• Mattresses
• Pillows
• Sofa cushions
• Office chairs
• Furniture padding
• Packaging foam
• Acoustic insulation
• Consumer comfort products

TDI-based foam can be manufactured in different softness and density levels according to the requirements of the end user.

Furniture Industry

Furniture manufacturers use Toluene Diisocyanate based polyurethane foam to produce seating products that provide comfort and maintain their shape over time.

Typical applications include sofas, armchairs, hotel furniture, office seating, decorative cushions, and modular furniture. The durability and resilience of flexible foam help improve product life while maintaining user comfort.

Mattress Manufacturing

The mattress industry is one of the main consumers of TDI 80/20. Polyurethane foam produced with TDI offers good airflow, lightweight construction, resilience, dimensional stability, and long service life.

Manufacturers can adjust the formulation to produce soft, medium, or firm mattress foam according to customer requirements.

Automotive Industry

TDI is also widely used in automotive interior applications. It helps manufacturers produce lightweight and comfortable parts for vehicles.

Common uses include:

• Car seats
• Headrests
• Armrests
• Door panels
• Dashboard padding
• Interior cushioning
• Acoustic components

The use of polyurethane foam can improve passenger comfort while helping reduce overall vehicle weight.

Polyurethane Adhesives

TDI is an important raw material in high-performance polyurethane adhesive systems used in demanding industrial environments.

These adhesives are widely used in furniture manufacturing, wood processing, footwear, construction, composite panels, and industrial assembly. They offer strong bonding performance, flexibility, and resistance to chemicals and moisture.

Polyurethane Coatings

Industrial polyurethane coatings formulated with Toluene Diisocyanate provide protection against abrasion, chemicals, moisture, and weathering.

Typical applications include industrial floors, wood coatings, marine coatings, metal protection, machinery finishes, and protective industrial surfaces. These coatings can improve durability while maintaining a smooth and attractive finish.

Polyurethane Elastomers

TDI is also used in the production of polyurethane elastomers, which combine flexibility with strong wear resistance and mechanical durability.

Typical products include industrial rollers, wheels, conveyor parts, mining components, mechanical parts, and heavy-duty industrial products.

Technical Characteristics

High quality Toluene Diisocyanate (TDI) generally offers high purity, stable NCO content, low viscosity, consistent color, and reliable processing behavior.

These characteristics are important because they help manufacturers maintain stable reaction performance and consistent product quality during large production runs.

Depending on the formulation, manufacturers may use amine catalysts to control reaction speed during polyurethane foam production.

Certain production systems may also require compatible industrial solvents for processing, cleaning, or coating formulations.

Glycols are used in various chemical formulations and may serve as intermediates or components in selected polyurethane systems.

TDI 80/20 Price

The Toluene Diisocyanate (TDI) 80/20 price is affected by several factors, including raw material costs, global supply and demand, production capacity, order quantity, packaging type, destination, freight rates, and market conditions.

Because TDI is an internationally traded chemical, the price may change depending on regional availability and logistics conditions. Buyers searching for the latest Toluene Diisocyanate price should always provide their required quantity, destination, preferred packaging, and Incoterms in order to receive an accurate quotation.

Basekim offers competitive TDI prices for full container loads, bulk shipments, regular orders, and long-term supply contracts. Customers can request the latest TDI price per ton based on their specific commercial and logistics requirements.

For a precise quotation, the following information is normally required:

• Required quantity
• Destination port or delivery location
• Preferred packaging
• Incoterms

This allows the sales team to calculate the most suitable commercial offer.

Packaging Options

TDI is commonly supplied in different packaging formats depending on customer volume and transport requirements.

250 kg Steel Drums

The 250 kg steel drum is one of the most common packaging options for international shipments. It offers safe handling, convenient storage, and easy loading for medium-volume customers.

ISO Tank

ISO tanks are suitable for large industrial users requiring bulk quantities. They can reduce packaging waste and improve unloading efficiency.

Bulk Road Tanker

For domestic and regional deliveries, bulk road tankers may be used where suitable unloading and storage facilities are available.

The final loading quantity depends on packaging type, container limitations, route restrictions, and the destination country’s transport regulations.

Storage and Handling

TDI is moisture-sensitive and must be stored under controlled conditions. Containers should remain tightly sealed and protected from water, humidity, and direct sunlight.

Recommended storage practices include:

• Keep containers closed
• Store in a dry and well-ventilated area
• Avoid moisture contamination
• Maintain the recommended storage temperature
• Follow the product SDS
• Use suitable personal protective equipment
• Follow all applicable transport and safety regulations

Proper handling helps maintain product stability, reduce contamination risks, and preserve shelf life.
