Toluene Diisocyanate (Tdi) Suppliers and Manufacturers

Hot sale Toluene Dissocyanate/TDI Toluene 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 market in 2000 Tdi 80/20 is used for Flexible Polyurethane Foam and other other polyurethane applications including elastomers,synthetic leather,coated fabrics,paints and adhesives. It is spray-applied,closed-cell polyurethane foam system with high fire resistance properties.it applies to all kinds of spray-applied thermal insulation engineering,such as building exterior cold rooms,large-scale pipeline,etc.

THF is an important organic synthetic raw material and a solvent with excellent performance. It is especially suitable for dissolving PVC, polyvinylidene chloride and butyl aniline. It is widely used as a solvent for surface coatings, anticorrosive coatings, printing inks, tape and film coatings, and used in combination. As a reaction solvent, the thickness and brightness of the aluminum layer can be arbitrarily controlled when used in the aluminum electroplating solution. THF itself can be polycondensed (ring-opening and repolymerization initiated by cations) into polytetramethylene ether glycol (PTMEG), also known as tetrahydrofuran homopolyether. PTMEG and toluene diisocyanate (TDI) are made into special rubbers with abrasion resistance, oil resistance, good low temperature performance and high strength; with dimethyl terephthalate and 1,4-butanediol to make block polyether polyester elastic Material.

Toluene is also known as toluol. It is a colorless clear aromatic hydrocarbon with the formula C7H8, it is also referred to by the name methyl benzene. Toluene occurs naturally at low levels in crude oil and is a byproduct in the production of gasoline by a catalytic reformer or ethylene cracker. It is also a byproduct of the production of coke from coal. Toluene is used across several industries for various applications. It is predominantly used as an appreciable solvent. Application: As a solvent, toluene can be used in paints, paint thinners, adhesives, inks, resins, cleaning agents, leather tanners and inks. It can also be used to manufacture polymers that produce nylon, plastic soda bottles and for pharmaceuticals, dyes and cosmetic products. Toluene is also used as a coolant in sodium cold traps underneath nuclear reactor loops. Packing: 220 kg Drum, IBC, ISO Tank, Flexi bag.
