Polypropylene Glycol

Polypropylene Glycol

Colorless to flaxen viscous liquid.
Non-volatile.
No corrosive.
General commodity

The molecular weight of the 400 ~ 2050. Relatively low molecular weight polymer is soluble in water.

High molecular weight polymer only slightly soluble in water, but soluble in oils, many hydrocarbon and aliphatic alcohol, ketones, ester etc. Molecules can esterification on both ends of the hydroxyl single or double ester were generated.

Its single ester is ionic of surfactant, also can and alcohol transamination ether. Is vegetable oil, resin and paraffin wax solvent, also used in preparation of alkyd resin, emulsifier, anti emulsifier, lubricating oil and plasticizer, etc. By epoxy propane and propylene glycol acid catalysts in the presence of high voltage or condensation.

Transparent, colorless or basic colorless viscous liquid.

According to the average molecular weight 425, 1025 and divided into three types of 2025.

Non-volatile. Soluble in water (low molecular weight one) and aliphatic ketone and alcohols etc., organic solvent, insoluble in ether and most aliphatic hydrocarbons.
