Methyl methacrylate (MMA) is an important organic compound in the field of chemical production raw materials and has a wide range of uses. MMA has many upstream and downstream related products, and some of the main upstream and downstream products will be described in detail below.

1. MMA upstream related products

1. Propylene: Propylene is one of the main raw materials of MMA, through oxidation, esterification and other reactions to produce methacrylic acid, and then further esterification to produce methyl methacrylate.
2. Methanol: Methanol is another important raw material that reacts with methacrylic acid to produce methyl methacrylate.
3. Sulfuric acid: Sulfuric acid is used as a catalyst in the production of MMA to promote the esterification reaction.

2. MMA downstream related products

1. Polymethyl methacrylate (PMMA):PMMA is a transparent plexiglass, with high transparency, weather resistance, chemical resistance and other characteristics, widely used in construction, automotive, electronics, medical and other fields.
2. Surface coating: MMA can be used as the basic raw material of coatings, mixed with other resins, pigments and other ingredients to make various coatings with excellent performance, which can be used in construction, automobile, furniture and other fields.
3. Adhesive: MMA can be made into an adhesive for bonding various materials, such as glass, metal, rubber, etc.
4. Ion exchange resin: MMA can be made into ion exchange resin for water treatment, chemical separation and other fields.

In conclusion, MMA, as an important organic compound, has a wide range of applications in the field of chemical production raw materials. Its upstream and downstream related products are numerous, involving various fields, such as construction, automotive, electronics, medical, water treatment, etc.
