Application:	Polypropylene glycol (PPG)is widely used as an antifoaming agent. For example, it can be used to controlfoam in the production of Bacillus thuringiensis-based biopesticides fromsewage sludge. It can be used in thepreparation of polyurethane(PU) elastomers. For example, it can be used tosynthesize PU elastomers with good acoustic absorption properties. PPG-2000 can be used as a soft segment in the preparationof PU-based self-healing polymeric networks. These networks find application in the field of soft electronics.
Features and Benefits:	• Long and flexible alkyl groups promotechain mobility, which facilitates rapid self-healing. • The methyl groups present on the sides of thepolymer improve emulsification in water.
General description:	Polypropylene glycol is an addition polymer of propylene glycol and water. It is represented by the formula HO(C₃H₆O)nC₃H₆OH in which n represents the average number of oxypropylene groups. Polypropylene glycol is soluble in water and in certain organic solvents as aliphatic ketones and alcohols and insoluble in ether and in most aliphatic hydrocarbons.
Packaging:	1 L in poly bottle
