What is Polypropylene Glycol usp?

Polypropylene Glycol usp is a polymer with the molecular formula H(C3H6O)nOH, an anemic to fade yellow thick liquid. Not unstable. Non-corrosive. The molecular weight of general products is 400 ~ 2050. Reduced molecular weight polymers are soluble in water. Greater molecular weight polymers are just reasonably soluble in water, soluble in oils, numerous hydrocarbons, and aliphatic alcohols, ketones, esters, and so forth. The hydroxyl teams at both ends of the particle can be esterified to create monoesters or diesters. Its monoester is a non-ionic surfactant, in addition to it can furthermore respond with alcohol to form ether. It is a solvent for vegetable oils, products in addition to paraffins, and is likewise made use of in the prep job of alkyd materials, emulsifiers, demulsifiers, lubing oils as well as plasticizers. It is gotten by the condensation of propylene oxide as well as additionally propylene glycol in the exposure of high pressure or acid stimulant.

Polypropylene Glycol usp Uses

  1. Polypropylene Glycol usp is a defoamer; solvent for veggie oils, waxes and resins. Used in eucalyptus sugar, drinks, sweet, yeast, and so on.
  2. Polypropylene Glycol usp is used in the production of yeast and also monosodium glutamate. The defoaming performance is several times to dozens of times that of edible oil.

Polypropylene Glycol usp Performance and Application

1. Polypropylene Glycol usp collection is soluble in toluene, ethanol, trichloroethylene in addition to different other natural solvents, PPG200, 400, 600 are soluble in water, and furthermore have lubricating, solubilizing, defoaming and also antistatic house or commercial houses. PPG-200 can be taken advantage of as a dispersant for pigments.

2. In cosmetics, PPG400 is utilized as emollient, softener along with lube.

3. Made use of as anti-foaming representative in finishings and also hydraulic oil, anti-foaming representative in synthetic rubber and also latex handling, cooling representative in addition to additionally coolant for heat transfer fluid, along with thickness improver.

4. It is used as an intermediate for esterification, etherification as well as polycondensation.

5. Utilized as mold and mildew as well as mold as well as mold release representative, solubilizer, additive for artificial oil, additive for water-soluble reducing liquid, roller oil, hydraulic oil, warm oiling compound, inner lube as well as also outdoors lubing material of rubber.

6. PPG-2000 ~ 8000 has exceptional lubrication, anti-foaming, heat-resistant and frost-resistant residential or commercial properties;

7. PPG-3000 ~ 8000 is mostly made use of as an element of including polyether to generate polyurethane foam;

8. PPG-3000 ~ 8000 can be utilized to generate plasticizers and lubes directly or after esterification;

9. This item can be taken advantage of as the base item of daily chemicals, medication and likewise oil.

Polypropylene Glycol usp Production Method

The polymerization of glycerol and purified propylene oxide is carried out under the catalysis of potassium hydroxide at a temperature of 90 to 95° C. and a pressure of 0.4 to 0.5 MPa. Then cool down to 60~70℃, press the material into the neutralizer, add water under stirring to neutralize excess potassium hydroxide, add phosphoric acid at 60~70℃ to neutralize to pH 6~7, then slowly heat up to 110~120℃, vacuum dehydration and filtration.
