Name : 2-A MPO 2-methyl-1,3-propanediol
Origin : DAIREN, Dalian, Taiwan CHEMICAL GORP.
Physics Performance :
Methylpropanediol is a transparent low viscosity liquid. Miscible with water, methanol, ethanol, butanol, propylene glycol, propylene glycol monomethyl ether, tetrahydrofuran, acetone, carbonate lactone, styrene, insoluble in cyclohexane, hexane, toluene, xylene. Viscosity increases at around -54°C and inconspicuous crystallization occurs.
