What are the upstream raw materials for hard foam? What do the downstream products contain?

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

Upstream associated items:



1. Polyol: Polyol is one of the main raw materials to the production of rigid foam, frequently applied polyols, polyester polyols and so on.

2. Isocyanate: Isocyanate is the main component of rigid foaming agent, frequently applied isocyanate, toluene diisocyanate and so on. Generally speaking

3. Furthermore Foaming agent: Foaming agent is the key component to create foam. Physical foaming agent and chemical foaming agent are frequently applied.

4. Moreover Catalyst: the catalyst is applied to promote the speed of hard foaming interaction, frequently applied amine catalyst and tin catalyst. Specifically Downstream associated items:



1. Building materials: As a building material, hard foam has excellent heat preservation, sound insulation, waterproof and other characteristics, and is able to be applied to wall insulation, roof insulation, floor insulation, etc. And

2. Refrigeration equipment: hard foam insulation performance is good, is able to be applied to manufacture refrigeration equipment such as refrigerators, freezers, etc. But From what I've seen,

3. But For instance Packaging materials: hard foam has the advantages of light weight, shockproof, moisture-proof, etc. For example, and is able to be applied to packaging electronic items, medical equipment, etc. But

4. Auto parts: Hard foam is able to be applied to manufacture auto parts such as seats, door panels, etc., with the advantages of light weight, sound insulation, and shock absorption. And In my experience, In fact In short, the upstream and downstream related items of hard foam are very extensive, involving construction, home appliances, automobiles, packaging and other fields.
