Toluene Diisocyanate (TDI) is a vital organic chemical raw material, primarily produced by the reaction of toluene diamine with phosgene. As a key component in polyurethane production, TDI is widely used in flexible foams, coatings, adhesives, elastomers, and more. TDI is available in two main isomeric forms: TDI-80 (80% 2,4-TDI and 20% 2,6-TDI) and TDI-100 (100% 2,4-TDI), with TDI-80 being the most commonly used industrial grade.
Key Features
High Reactivity: TDI contains highly reactive isocyanate groups (-NCO), which can react with hydroxyl, amino, and other functional groups to form polyurethane materials.
Excellent Mechanical Properties: Provides polyurethane materials with superior elasticity, wear resistance, and tear strength.
Low Viscosity: Easy to process and mix, suitable for various production processes.
Stability: Stable under dry storage conditions but should be kept away from moisture.
Applications
Flexible Polyurethane Foam: Used in furniture, mattresses, car seats, and more, offering comfortable support and elasticity.
Coatings and Paints: Acts as a curing agent in high-performance coatings, providing excellent adhesion, wear resistance, and chemical resistance.
Adhesives and Sealants: Used in construction, automotive, footwear, and other industries, delivering high strength and durability.
Elastomers: Used to manufacture industrial parts, tires, seals, and more, offering excellent elasticity and wear resistance.
Other Applications: Used in waterproofing materials, insulation, textile coatings, and more.
Packaging & Storage
Packaging: Available in 250 kg/drum, 1000 kg/IBC, or tanker shipments. Custom packaging options are available upon request.
Storage: Store in a cool, dry, and well-ventilated area. Avoid contact with water, alcohols, amines, and other reactive substances. Recommended storage temperature: 15-25℃.

Safety & Environmental Considerations
Toxicity: TDI is irritating to the skin, eyes, and respiratory system. Proper protective equipment (e.g., gloves, goggles, respirators) must be worn during handling.
Flammability: Although the flash point is relatively high, keep away from open flames and high temperatures.
Environmental Impact: Dispose of waste materials in accordance with local environmental regulations to prevent pollution.
