Hard foam polyether is an important raw material for chemical production, which is widely used in thermal insulation materials, building materials, furniture, automobiles, packaging and other fields. Its upstream and downstream related products are numerous, which will be described separately below.

Upstream Related Products:

1. Propylene oxide: Propylene oxide is one of the main raw materials for the production of rigid foam polyether and is used to prepare polyether polyols.
2. Acrylonitrile: Acrylonitrile is also one of the raw materials for the production of rigid foam polyether, which reacts with propylene oxide to generate acrylate, and then further reacts to generate polyether polyol.
3. Catalyst: In the process of producing rigid foam polyether, it is necessary to use a catalyst to promote the polymerization reaction. Commonly used catalysts include basic catalysts and acidic catalysts.

downstream related products:

1. rigid polyurethane foam: rigid foam polyether is one of the main raw materials for the production of rigid polyurethane foam, which reacts with polyisocyanates to form foam.
2. Thermal insulation material: Rigid polyurethane foam is an excellent thermal insulation material. It has the advantages of low thermal conductivity, good thermal insulation performance and light weight. It is widely used in construction, refrigeration, pipeline and other fields.
3. Building materials: Rigid polyurethane foam can also be used as building materials for the production of insulation panels, wall materials, roofing materials, etc.
4. Furniture: Rigid polyurethane foam can be used to produce furniture, such as sofas, mattresses, etc., with high comfort and good durability.
5. packaging materials: rigid polyurethane foam can also be used for packaging materials, with good protection performance, light and easy processing.

In short, there are many upstream and downstream related products of hard foam polyether, involving many fields, such as chemical industry, building materials, furniture, automobile, packaging and so on. With the increasing market demand, the production technology and application fields of hard foam polyether are also expanding.
