In the field of chemical production raw materials, the upstream and downstream related products of hard foam are very extensive. The following are some common hard foam upstream and downstream related products:

upstream related products:

1. polyol: polyol is one of the main raw materials for the production of hard foam, commonly used polyols, polyester polyols and so on.
2. Isocyanate: Isocyanate is the main component of rigid foam foaming agent, commonly used isocyanate, toluene diisocyanate, etc.
3. foaming agent: foaming agent is the key component of foam, commonly used physical foaming agent and chemical foaming agent.
4. catalyst: catalyst is used to promote the speed of rigid foam foaming reaction, commonly used amine catalyst and tin catalyst.

downstream related products:

1. Building materials: hard foam as a building material has excellent heat preservation, sound insulation, waterproof and other properties, and can be used for wall insulation, roof insulation, floor insulation, etc.
2. Refrigeration equipment: hard foam insulation performance is good, can be used to manufacture refrigeration equipment such as refrigerators, freezers, etc.
3. Packaging materials: hard foam has the advantages of light weight, shockproof, moisture-proof, etc., and can be used for packaging electronic products, medical equipment, etc.
4. Auto parts: Hard foam can be used to manufacture auto parts such as seats, door panels, etc., with the advantages of light weight, sound insulation, and shock absorption.

In short, the upstream and downstream related products of hard foam are very extensive, involving construction, home appliances, automobiles, packaging and other fields.
