[Chemical Knowledge]:What are the upstream raw materials for ethyl methacrylate? What are the downstream products?

Ethyl methacrylate (EMA) is an important organic chemical raw material, which is widely used in polymer synthesis, coatings, adhesives, fibers and other fields. In the field of raw materials for chemical production, the upstream and downstream related products of ethyl methacrylate mainly include the following categories:

upstream products:

1. Acrylic acid: Acrylic acid is one of the main raw materials of ethyl methacrylate, and ethyl methacrylate can be produced by esterification reaction.
2. Ethanol: Ethanol, as another raw material of ethyl methacrylate, is esterified with acrylic acid to produce ethyl methacrylate.

downstream products:

1. Polymer: ethyl methacrylate can be copolymerized with other monomers to produce polymers with various properties. Such as copolymerization with methyl methacrylate, high transparency, high impact strength of the organic glass; copolymerization with styrene, acrylonitrile, etc., can be oil resistance, solvent resistance, excellent heat resistance of engineering plastics.
2. coatings: ethyl methacrylate can be used as the main film-forming material of coatings, with excellent weather resistance, light retention, color retention and scratch resistance. Can be used for construction, automotive, home appliances and other fields of painting.
3. Adhesive: Ethyl methacrylate can be used as the monomer of the adhesive and copolymerized with other monomers to make the adhesive. It has the characteristics of high bonding strength, good water resistance and strong weather resistance. It can be used for the bonding of wood, paper, leather and other materials.
4. Fiber: Ethyl methacrylate can be used as a monomer of fiber and copolymerized with other monomers to make fiber. It has the characteristics of softness, comfort and anti-wrinkle, and can be used in clothing, home textiles and other fields.

In short, ethyl methacrylate has a wide range of upstream and downstream related products in the field of chemical production raw materials, which is of great significance to promote the development of the chemical industry.
