Methylene Diphenyl Diisocyanate (MDI)
CAS : 62-53-3 HS Code : 292141000 Packing : 200kg/drum 23ton per tank 1) Aniline, phenylamine or aminobenzene is an organic compound with the formula C6H7N. Aniline is the simplest and one of the most important aromatic amines, being used as a precursor to more complex chemicals. 2) Being a precursor to many industrial chemicals, its main use is in the manufacture of precursors to polyurethane. The largest application of aniline is for the preparation ofmethylene diphenyl diisocyanate (MDI). 3) Other uses include rubber processing chemicals (9%), herbicides (2%), and dyes and pigments (2%).As additives to rubber, aniline derivatives such as phenylenediamine[disambiguation needed] and diphenylamine, are antioxidants. Illustrative of the drugs prepared from aniline is paracetamol (acetaminophen, Tylenol). The principal use of aniline in the dye industry is as a precursor to indigo, the blue of blue jeans. 4)Aniline is also used at a smaller scale in the production of the intrinsically conducting polymerpolyaniline.
Diphenylmethane diisocyanate, or "MDI" for short, is a white to pale yellow molten solid, containing 4,4 '-diphenylmethane diisocyanate, 2,4' -diphenylmethane diisocyanate, 2,2 '-diphenylmethane diisocyanate, and other isomers. Is the aromatics downstream main products, widely used in polyurethane elastomers, synthetic fiber, artificial leather, solvent-free coatings and other polyurethane materials production field.

Dimethyl carbonate is abbreviated as DMC. At room temperature, it is a colorless, transparent, pungent odorous liquid. The relative density (d204) is 1.0694, the melting point is 4C, the boiling point is 90.3C, the flash point is 21.7C (opening), 16.7C (closed) ), refractive index (nd20Chemicalbook) 1.3687, flammable, non-toxic. It can be mixed with almost all organic solvents such as alcohol, and ester in any ratio, and is slightly soluble in water. Can be used as a methylating agent. Compared with other methylation reagents, such as methyl iodide and dimethyl sulfate, dimethyl carbonate is less toxic and biodegradable. The physical and chemical properties: Model NO. 99% Molecular weight� 60.1g/mol Hydroxyl No. Monohydroxy Appearance Colorless Liquid Available chlorine content 2-13.4%(V) Properties Miscible Storage condition Flammables area Freezing point -89.5C Applications: 1. A new type of low-toxicity solvent can replace solvents such as toluene, xylene, ethyl acetate, butyl acetate, acetone or methyl ethyl ketone in the paint and adhesive industries. It is an environmentally friendly green chemical product. 2. Good methylating agent, carbonylating agent, hydroxymethylating agent and methoxylating agent are a kind of chemical raw materials with a wide range of uses. 3. Chemicalbook wants to replace phosgene, dimethyl sulfate, methyl chloroformate and other highly toxic drugs. 4. Synthetic polycarbonate, diphenyl carbonate, isocyanate, etc. 5. In medicine, it is used to synthesize anti-infective drugs, antipyretic and analgesic drugs, vitamin drugs, and central nervous system drugs. 6. Pesticides are mainly used to produce methyl isocyanate, and then to produce certain carbamate drugs and insecticides (anisole). 7. Gasoline additives, lithium battery electrolyte, etc.

Extruded Polyurethane(TPU) Tube [Material Description]          Thermoplastic Polyurethane(TPU), is an (AB)n type linear polymeric chains in block-structures. A is a polyester or polyether with molecular weight (1000-6000), B is a diol containing 2-12 straight chain carbon atoms. The chemical structure of AB segments is linked by diisocyanates, usually which is MDI. The currently available TPUs can be divided mainly in two groups: polyester-based TPUs and polyether-based TPUs. TPU is white ruleless spherical or cylindrical particles with relative density of from 60A to 90D.The relative density of polyether-based TPUs is smaller than that of the polyester-based TPUs.  [Properties]                 Excellent wear resistance                 Excellent elasticity and ductility, outstanding carrying capability, impact resistance & shock absorption                 Outstanding low temperature performance: TPU has very low glass transition temperature; it has good elasticity, flexibility and other excellent physical properties.                 Wide hardness range:    60A-55D              Excellent biocompatibility  [Application]                 IV catheters, catheter sheaths  [Sizes]                 inner diameter: 0.40mm-10.00mm                 wall thickness: 0.20mm-3.00mm  [Grade]                 USP Class VI, Food & Beverage Grade, Industrial grade                 With 20-40% Baso4 developing agent  [Production Environment]                Standard Class 100,000 Cleanroom
