As an important raw material for chemical production, combined polyether is widely used in polyurethane foam and other fields. Its upstream and downstream related products are numerous, and some of the main upstream and downstream products will be described in detail below.

upstream products:

1. Polyol: Polyol is one of the main raw materials of the combination of polyether. Commonly used polyols include ethylene glycol, propylene glycol, butylene glycol, etc. These polyols play a role in the production of the combination polyether to adjust the molecular weight and functionality, affecting the properties of the combination polyether.
2. Isocyanates: Isocyanates are another important raw material for the combination of polyethers. Commonly used isocyanates include diphenylmethane diisocyanate (MDI), toluene diisocyanate (TDI), etc. Isocyanates react with polyols to form polyurethanes.
3. Catalyst: In the production process of combined polyether, it is necessary to add catalyst to improve the reaction rate. Commonly used catalysts include amine catalysts and tin catalysts.
4. Additives such as flame retardants and foaming agents: According to specific needs, additives such as flame retardants and foaming agents may be added in the production process of combined polyether to improve the performance of polyurethane foam.

downstream products:

1. Polyurethane foam: Combined polyether is one of the main raw materials and can be used to produce polyurethane foam. Polyurethane foam has excellent thermal insulation, sound insulation, seismic performance, widely used in construction, home appliances, automobiles and other fields.
2. Coatings: Polyether can also be used in the production of polyurethane coatings, with excellent weather resistance, chemical resistance, decorative and other advantages, can be used for construction, automobile, ship and other fields of coating.
3. Adhesive: combination polyether can also be used to produce polyurethane adhesive, with high strength, water resistance, oil resistance and other characteristics, can be used for wood processing, footwear, packaging and other industries.

In short, the combination of polyether upstream and downstream related products, involving a wide range of applications. With the continuous progress of science and technology, the types and properties of combined polyether and its related products are constantly improving and improving, providing more possibilities and choices for the development of various fields. At the same time, we also need to pay attention to environmental protection and sustainability in the production process, and promote the green development of the chemical industry.
