Propylene glycol ether (Propylene Glycol Ethyl Ether, referred to as PGEE) is a common chemical raw material, widely used in coatings, inks, cleaning agents, solvents and other fields. In the upstream and downstream industry chain of propylene glycol ether, there are many related products, and the following will detail several of the main upstream and downstream related products.

upstream related products:

1. propylene glycol (Propylene Glycol, referred to as PG): propylene glycol is a colorless, odorless, transparent, viscous liquid, can be used as a solvent, moisturizing agent, preservatives, etc., widely used in food, medicine, cosmetics and other fields. Propylene glycol ether production process, propylene glycol is one of the main raw materials.

2. Ethylene oxide (Ethylene, EO): Ethylene oxide is a colorless, flammable, and toxic gas that can be used to produce chemicals such as ethylene glycol, ethanolamine, and glyoxal. In the production of propylene glycol ethyl ether, ethylene oxide reacts with propylene glycol to produce propylene glycol ethyl ether.

downstream related products:

1. coating: propylene glycol ether can be used as a solvent in the coating to help adjust the viscosity, drying and leveling properties of the coating, and improve the construction performance and film-forming performance of the coating.

2. ink: propylene glycol ether in the ink can be used as a solvent and regulator, improve the fluidity of the ink and printing performance, while reducing the viscosity of the ink, improve the printing effect.

3. cleaning agent: propylene glycol ether has excellent solubility and cleaning ability, can be used as the main component of the cleaning agent, used to clean metal, plastic and other surface oil stains and stains.

4. Solvent: Propylene glycol ether can be used as a solvent for a variety of chemicals, such as dyes, resins, fragrances, etc., to help improve the solubility and dispersion of these chemicals.

In short, there are many upstream and downstream related products of propylene glycol ether, involving many fields, such as coatings, inks, cleaning agents, solvents, etc. The production and application of these related products are closely related to the production and development of propylene glycol ether, and together constitute a complete industrial chain in the field of chemical production raw materials.
