Methyl stearate is an ester organic compound, also known as methyl octadecanoic acid. It is a monoalkyl ester formed from long-chain fatty acids. It is a colorless or slightly yellow transparent oily liquid to semi-solid at room temperature, with excellent permeability, thermal stability and antistatic properties. Melting point 37~39℃, density 0.84g/cm3, insoluble in water, soluble in methanol, ethanol, DMSO and other organic solvents.
Methyl stearate can be used to prepare insulation materials:
Methyl stearate is an organic phase change energy storage material. The use of phase change materials in buildings can make full use of renewable energy such as solar energy and seasonal temperature differences, reduce the ambient temperature fluctuations of buildings, and reduce energy consumption.
Methyl stearate can be combined with other materials to prepare composite insulation materials. The insulation materials include methyl stearate, ethyl stearate, hardened Fatty acid salts and light porous inorganic materials as porous carriers adsorb and fill the molten methyl stearate, ethyl stearate and stearate into the pores of the porous carrier, and at the same time, the pores of the porous material can be utilized The adsorption force of the wall and the strength of the porous material itself prevent the phase change material from leaking during the heat absorption and release process.
