Ordinary soft foam is a widely used material in the field of chemical production raw materials. It has the characteristics of light weight, softness and high resilience, so it is widely used in furniture, automobiles, construction, packaging and other fields. The upstream and downstream related products of ordinary soft foam mainly include raw materials, auxiliary materials and finished products.

1. upstream related products

1. Polyether polyol

Polyether polyol is one of the main raw materials of ordinary flexible foam, which is made of ethylene oxide, propylene oxide and other epoxides and polyol starter in the catalyst under the action of ring opening polymerization. The molecular weight, functionality and hydroxyl value of polyether polyol have a great influence on the performance of flexible foam.

2. polyisocyanate

polyisocyanate is another main raw material of ordinary flexible foam, commonly used with multi-phenyl polyisocyanate, methyl phenyl polyisocyanate, etc. Polyisocyanates react with polyether polyols to form polyurethanes, thereby obtaining ordinary flexible foams.

3. Additive

The production process of ordinary flexible foam also needs to add some auxiliary materials, such as catalysts, foaming agents, stabilizers, etc., to improve the performance of flexible foam.

2. downstream related products

1. Furniture

ordinary soft foam as furniture cushion and backrest material, with high comfort, good resilience and other advantages, so it is widely used in sofa, chair and other furniture products.

2. Car interior

Ordinary soft foam is also widely used in car interiors, such as seats, door panels, dashboards, etc., which can improve the comfort and safety of cars.

3. Building insulation material

ordinary soft foam as building insulation material, has good thermal insulation performance and environmental protection, is widely used in exterior wall insulation, roof insulation and other fields.

4. packaging materials

ordinary soft foam can also be used as packaging materials, with strong protection, light and easy processing, etc., are widely used in electronic products, medical equipment and other products in the packaging.

In short, ordinary flexible foam has a wide range of applications in the field of chemical production raw materials, and its upstream and downstream related products cover many fields, which is of great significance for promoting economic development and improving people's quality of life.
