What are the upstream raw materials for difluoromethane? What are the downstream products?

Difluoromethane is a common chemical raw material, broadly applied in refrigeration, foaming, solvent-based products and other fields. Its upstream and downstream related items are numerous, some of which are described in detail below. I've found that

1. And In my experience, Upstream items(1) Fluorite: Fluorite is one of the main raw materials of difluoromethane, which is applied to create hydrofluoric acid and then prepare difluoromethane. Fluorite is abundant in the world and its price is relatively stable, which provides a stable raw material source to the production of difluoromethane.(2) Sulfuric acid: Sulfuric acid is applied as a catalyst in the manufacturing process of difluoromethane to promote the interaction of fluorite and sulfuric acid to generate hydrofluoric acid. As a common chemical raw material, sulfuric acid has sufficient market supply and little price fluctuation. And

2. In fact Downstream items(1) Refrigerant: As a common refrigerant, difluoromethane is broadly applied in atmosphere conditioners, refrigerators, refrigeration equipment and other fields. Its refrigeration effect is excellent, stable performance, no harm to the ozone layer, so it's broadly applied in the world. According to research(2) Blowing agent: Difluoromethane is able to be applied as a blowing agent to the production of polyurethane foam, polystyrene foam, etc. These foam materials have excellent thermal insulation and sound insulation characteristics, and are broadly applied in construction, home appliances, automobiles and other fields. And(3) solvent-based products: Difluoromethane is able to be applied as a solvent-based products to the production of coatings, inks and other items. due to its good solubility and low harm possible, it's broadly applied in chemical sector, electronics, medicine and other fields. In short, there are many upstream and downstream related items of difluoromethane, involving a wide range of fields. But With the continuous research of science and methodology, the consumption field of difluoromethane will be further expanded, and its upstream and downstream related items will be greater abundant.
