As an accredited TDI factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.
| Packing | TDI is typically packaged in 250 kg steel drums, labeled with hazardous material warnings, product details, and manufacturer information. |
| Shipping | Toluene diisocyanate (TDI) is shipped in tightly sealed steel drums, iso-tanks, or bulk containers under dry and cool conditions. It must be protected from moisture, heat, and direct sunlight. TDI is classified as a hazardous material; appropriate labeling, handling, and transportation regulations must be strictly followed to ensure safe delivery. |
| Storage | Toluene diisocyanate (TDI) should be stored in tightly closed, stainless steel or lined containers, away from moisture, direct sunlight, heat, and incompatible substances such as amines and acids. Storage areas should be cool, well-ventilated, and equipped with spill containment. TDI is sensitive to water, which can cause hazardous reactions, so ensure all containers and systems remain dry and sealed. |

Purity 99.9%: TDI with 99.9% purity is used in flexible polyurethane foam manufacturing, where it ensures superior foam resilience and consistency. Viscosity Grade Low: TDI of low viscosity grade is used in spray foam insulation, where it provides enhanced flowability and uniform cell structure. Molecular Weight 174.15 g/mol: TDI with a molecular weight of 174.15 g/mol is used in the production of elastomeric coatings, where it delivers optimal cross-linking density for improved mechanical strength. Melting Point −22°C: TDI with a melting point of −22°C is used in cold-curing adhesives, where it enables effective application at lower temperatures. Free Acid Content ≤0.01%: TDI with free acid content ≤0.01% is used in automotive seat foam formulations, where it minimizes undesirable side reactions for increased product stability. Stability Temperature 40°C: TDI with a stability temperature of 40°C is used in prepolymer systems, where it maintains performance integrity during storage and handling. Volatile Content ≤0.05%: TDI with volatile content ≤0.05% is used in mattress production, where it helps achieve low emission standards for enhanced indoor air quality. |
