Elastomer polyether is an important raw material for chemical production, which is widely used in polyurethane, elastic fiber, coating, adhesive and other fields. Its upstream and downstream related products are numerous, which will be described in detail below.

upstream associated products:

1. Ethylene oxide: one of the main raw materials of elastomeric polyether, prepared by the polymerization of ethylene oxide and polyols. The production process of ethylene oxide mainly includes chlorohydrin method and oxidation method, of which oxidation method is the mainstream production method at present.
2. Polyol: Polyol is another main raw material of elastomer polyether. Commonly used polyols include ethylene glycol, propylene glycol, butylene glycol, etc. The production methods of polyols are mainly petrochemical route and biological route, in which the petrochemical route dominates.

downstream related products:

1. Polyurethane: Elastomer polyether is one of the important raw materials of polyurethane, which can be used to produce polyurethane foam, elastomers, coatings, etc. Polyurethane has excellent properties, such as wear resistance, impact resistance, waterproof, etc., and is widely used in construction, automobiles, home appliances and other fields.
2. Elastic fiber: Elastomer polyether can be used to produce elastic fiber, such as spandex, polyester, etc. Elastic fiber has excellent elasticity and recovery, and is widely used in textile, clothing and other fields.
3. Coating: Elastomer polyether can be used as the base resin of the coating to improve the elasticity and weather resistance of the coating. Coatings can be used in construction, automobiles, ships and other fields to play a role in protection and decoration.
4. Adhesives: Elastomer polyethers can be used to produce adhesives with excellent adhesion and weather resistance. Adhesives are widely used in construction, packaging, automotive and other fields.

In summary, there are many upstream and downstream related products of elastomer polyether, involving many fields, such as construction, automobiles, home appliances, textiles, clothing, etc. With the continuous progress of science and technology and the continuous expansion of application fields, the types and properties of elastomeric polyether and its related products are also constantly improving, providing strong support for the development of various industries.
