Apply：
Surface coating：Due to the high solubility of high polymeric PVC resins，It can be used as a coating solvent for synthetic leather, etc.。
Sticker：Exercising its superior solubility and proliferation characteristics，It's an ethylene.、Solvent use of adhesives such as epoxy resin。
The mold.：Thermal condensation membranes and drying agents usable for PVC resins。
Ink printing：Due to its ease of soluble inorganic compounds，And it evaporates fast.，So it's perfect for printing ink solvents.。
Other：Because it dissolves all kinds of resin under constant temperatures.，And it's soluble with water and general organic solvents.，So it's widely used as a solvent for special resins, such as luminous resins.。And...，He's also reacting as a Gertrude.、Reaction solvents and medicine in Vittig's reaction、Reactions and precision solvent use during manufacture, such as pesticides。
