一．Product Property
Polyetheramine is obtained by ammoxidation of polyethylene glycol, polypropylene glycol or ethylene glycol/propylene glycol copolymer under high temperature and high pressure. By choosing different polyalkoxyl structures, the reactivity, toughness, viscosity and hydrophilicity of polyetheramine can be adjusted, and the amino groups provide the possibility for polyetheramine to react with various compounds.It is soluble in organic solvents such as ethanol, ethylene glycol ethers, ketones, aliphatic hydrocarbons, and aromatic hydrocarbons.

It can be stored in the air at room temperature for a long time. However, it is recommended to use nitrogen protection during all storage to reduce the impact of accidental exposure to high temperatures and to minimize the absorption of moisture and carbon dioxide from the atmosphere. At the same time, it should be stored in the original container, placed in a dry, cool and well-ventilated warehouse, avoiding direct sunlight and keeping away from acidic substances. At temperatures above 60℃, significant discoloration may occur.
