Hydroxyethyl methacrylate (HEMA) is an important chemical raw material, which is widely used in polymer synthesis, coatings, adhesives, fiber treatment and other fields. Its upstream and downstream related products are numerous, the following lists some of the main upstream and downstream products:

upstream products:

1. Acrylic acid: Acrylic acid is one of the important raw materials for the production of hydroxyethyl methacrylate, through esterification reaction can be produced hydroxyethyl methacrylate.
2. Ethanol: Ethanol, as another raw material in the production of hydroxyethyl methacrylate, is esterified with acrylic acid to produce hydroxyethyl methacrylate.

downstream products:

1. Polymer: hydroxyethyl methacrylate can be used as a monomer, copolymerized with other monomers to generate a variety of polymers, such as acrylic emulsion, water-based coatings.
2. Adhesive: Hydroxyethyl methacrylate can be used to produce adhesives, such as pressure-sensitive adhesives, hot melt adhesives, etc., with good bonding performance and weather resistance.
3. fiber treatment agent: hydroxyethyl methacrylate can be used as a fiber treatment agent to improve the moisture absorption, flexibility and antistatic properties of the fiber.
4. Ion exchange resin: Hydroxyethyl methacrylate can be used to prepare ion exchange resin, which can be used in water treatment, chemical separation and other fields.

In short, as an important chemical raw material, hydroxyethyl methacrylate has a wide range of upstream and downstream related products, which is of great significance to promote the development of the chemical industry.
