Polyether is an important raw material for chemical production, which is widely used in various fields. In the upstream and downstream industry chain of polyether, there are many related products. This article will detail the upstream and downstream associated products of polyether.

1. Upstream Associated Products

1. Ethylene Oxide

Ethylene oxide is one of the main raw materials for the production of polyether. It is prepared by oxidizing ethylene and then reacting with water to produce ethylene glycol. The ethylene glycol is further polymerized to form a polyether.

2. Propylene

Propylene is another raw material for the production of polyethers. It undergoes an oxidation reaction to produce propylene oxide and then reacts with water to produce propylene glycol. Propylene glycol is further polymerized to form a polyether.

3. Styrene

Styrene can also be used as a starting material for the production of polyethers in certain specific cases. It can be copolymerized with other olefin monomers to produce polyethers with specific properties.

2. downstream related products

1. Polyurethane foam

polyether is one of the important raw materials for the production of polyurethane foam. It is mixed with polyols, isocyanates and other raw materials, through the foaming reaction to produce polyurethane foam. Polyurethane foam is widely used in heat preservation, sound insulation, shock absorption and other fields.

2. Surfactant

polyethers can also be used as starting materials for surfactants. By reacting with an acidifying agent such as sulfuric acid and hydrochloric acid, a substance having an excellent surface activity can be produced to improve cleaning, emulsification and the like.

3. Lubricating Oil Additives

polyethers can also be used as raw materials for lubricating oil additives. By compounding with other compounds, the anti-wear and anti-oxidation properties of lubricating oil can be improved.

4. Elastomer

polyethers can also be used to produce elastomers. By blending or copolymerizing with other polymer materials, materials with excellent elasticity can be prepared for the manufacture of seals, shock absorbers, etc.

In short, as an important raw material for the production of chemicals, polyether has a wide range of upstream and downstream related products and many applications. With the continuous development of science and technology, the types and properties of polyether and its related products will be further improved, providing more possibilities for the development of various fields.
