Methylene Diphenyl Diisocyanate (MDI) Mix of CAS:26447-40-5 & CAS:101-68-8 Methylene Diphenyl Diisocyanate is produced by a 4 steps reaction based on benzene as feedstock. There are 3 isomers of MDI : 2,2-MDI, 2,4-MDI, and 4,4-MDI. The 4,4 isomer is known as pure or monomeric MDI (mMDI).The Polymeric MDI so called Crude MDI contains monomeric MDI […]

TriPropylene Glycol (TPG)
Tripropylene Glycol or TPG is mixture of isomers present as a clear liquid, odorless and with a medium viscosity. It’s naturally hygroscopic (it attracts water from atmosphere). It is completely soluble in water and miscible with many organic solvents. The molecular formula is C9H20O4.
Tripropylene Glycol Chemical Structure Composition.
Tripropylene glycol is a by-product of the manufacture of monopropylene glycol. At high temperature and pressure, water is added to propylene oxide, which results in the formation of mono propylene glycol (90%) and mixture of propylene glycol and tripropylene glycol (10%).
Triproylene Glycol is used in both industrial applications and consumer products.
TPG is commonly used as a raw material for the production of polymers such as polyesters and alkyd resins, as a plasticizer in polymers such as PVC, and as a component in cleaning agents, coatings, lubricants, cutting oils and printing inks. It is also used as a chemical intermediate in urethanes.
In the field of consumer applications, TPG is used in the formulation of products such as fragrances, soaps and cosmetics.
