Product Description Product DescriptionTDI 80/20 Toluenes Diisocyanate Product:Toluene Diisocyanate 80/20 or TDI 80/20CAS number: 584-84-9Molecular formula: C9H6N2O2Molecular weight: 174.15Synonym:2,4-Diisocyanatotoluene; Benzene, 1,3-diisocyanatomethyl-; TDI, DiisocyanatolueneQuality Standard:Q/DHJ.02.02-1999Appearance: water-with to pale yellow clear liquid with irritating odour.Description: TDI is colorless and transparent to primrose yellow liquid, with pungent smell, insoluble in water, soluble in Aceton, ethyl acetate and toluene.IntroductionIntroductionToluene diisocyanate (TDI) is an aromatic diisocyanate that is a clear, pale yellow liquid with a sharp, pungent odor, which is insoluble in water and miscible with most common organic solvents. TDI (CAS No. 26471-62-5) consists of two isomers: toluene-2,4-diisocyanate (2,4-TDI) (CAS No. 584- 84-9) and toluene-2,6-diisocyanate (2,6-TDI) (CAS No. 91- 08-7), which is commercially produced in different ratios. The most common ratio is 80% 2,4-TDI/20% 2,6 TDI. TDI is widely used and accounted for 34% of the global isocyanate marketProduct ParametersSpecifictaionTest ItemIndexTest ResultPurity(WT)%99.7min99.82,4-Isomer%80+/-179.62,6-Isomer%20+/-119.6Acidity%(HCL)0.0015MAX0.0004Hydrolyzable Chloride(WT)%0.004MAX0.0033Color (APHA)15 MAX5Total Chloride(WT)%0.018 MAX0.005AppearanceIn compliance with the above specification.Products UsageApplicationTDI (toluene diisocyanate) is a kind of commonly used polyisocyanate, which is polyurethane (PU) material and important basic raw material. It is mainly used for producing flexible polyurethane foam and polyurethane elastomers, coatings, adhesives and so on. Storage: sealed with argon or nitrogen, cool, dry and protected from light.Packaging & StoragePackage: 250kg net in new steel drum (Tare weight:22kg) Storage TDI80/20 containers should be kept properly closed and stored indoors in a well-ventilated and fire-proof place.When opening the containers, operators should wear go les, gloves and rubber aprons.Containers should be handled carefully to avoid damage. In case of leakage, transfer it into another proper container in a well ventilated and dry place. When opening the cap, use an opener or wrench. Once the cap is loosened, pause until the high pressure in the container equalizes with the atmospheric pressure, then open the cap slowly. Company Profile
