Toluene diisocyanate (TDI)
Toluene diisocyanate (TDI) is an aromatic diisocyanate.
It is produced for reaction with polyols to form polyurethanes.
It exists in two isomers, 2,4-TDI and 2,6-TDI. 2,4-TDI is produced in the pure state,
but TDI is often marketed as 80/20 and 65/35 mixtures of the 2,4 and 2,6 isomers respectively.
Karoon petrochemical TDI grade is 80/20.

Methylene diphenyl diisocyanate (MDI)
Methylene diphenyl diisocyanate, most often abbreviated as MDI, is an aromatic diisocyanate.
It exists in three isomers, 2,2'-MDI, 2,4'-MDI, and 4,4'-MDI. The 4,4' isomer is most practically useful,
and is also known as Pure MDI. MDI is reacted with a polyol in the manufacture of polyurethane.
It is the most produced diisocyanate.
Note: Karoon Petrochemical Co. MDI plant is under construction and product is not available yet.
Hydrochloric Acid
Hydrochloric acid is the solution of hydrogen chloride (HCl) in water.
It is a highly corrosive, strong mineral acid, and therefore has major industrial use.
The large-scale production of hydrochloric acid is almost always integrated with other industrial
scale chemicals production.In Karoon HCl is produced as by-product of Toluene diisocyanate (TDI).

Bleach
Sodium hypochlorite is a chemical compound with the formula NaOCl. Sodium hypochlorite solution,
commonly known as bleach. Bleach is a chemical that removes color or whitens, often via oxidation.
Common chemical bleaches include household "chlorine bleach".
