About: Methylpropylene glycol is a colorless transparent liquid with low viscosity. Miscible with water, methanol, ethanol, butanol, propylene glycol, propylene glycol monomethyl ether, tetrahydrofuran, acetone, carbonate lactone, styrene, insoluble in cyclohexane, hexane, toluene, xylene. At about -54℃, the viscosity increases and the crystallization is not obvious. Applications: Methyl propylene glycol can be used in the manufacture of unsaturated polyester, liquid saturated polyester, thermoplastic polyester resin (PET and PBT modification), alkyd resin, polyurethane resin, double ester type plasticizers, lubricants, etc. Also used in cosmetics, pharmaceuticals and so on. The obtained polymer has the characteristics of low viscosity, low melting point, low temperature resistance and weather resistance. In the field of polyurethane, it is used to produce polyester polyols with low crystallization, and can be used as chain extender. The application fields are synthetic leather paste, polyurethane coating, polyurethane adhesive for food flexible packaging composite. Preparation: In industry, propylene oxide is isomerized…
