What are the upstream raw materials of PTFE? What do the downstream products contain?

Polytetrafluoroethylene(PTFE) is a kind of high-performance fluorine plastic, which has excellent chemical corrosion resistance, high temperature resistance, low temperature resistance, wear resistance, non-stick and other characteristics. it's broadly applied in chemical sector, machinery, electronics, medical treatment, aerospace and other fields. In the field of raw materials to chemical production, the upstream and downstream related items of PTFE mainly have the following aspects:

Upstream raw materials:



1. Fluorite: Fluorite is one of the main raw materials to the production of PTFE, which is applied to prepare tetrafluoroethylene monomer.

2. Anhydrous hydrofluoric acid: Anhydrous hydrofluoric acid is the key raw material to the preparation of tetrafluoroethylene monomer, which is obtained by reacting with fluorite. Downstream associated items:



1. Tetrafluoroethylene monomer: PTFE is prepared by the polymerization of tetrafluoroethylene monomer, so tetrafluoroethylene monomer is the direct downstream product of PTFE.

2. Filling modified PTFE: In order to enhance the mechanical characteristics and thermal stability of PTFE, various fillers is able to be added to filling modification, such as glass fiber, carbon fiber, graphite, etc.

3. Expanded PTFE: Expanded PTFE is a kind of PTFE with microporous structure, which has high specific surface area and good atmosphere permeability. it's broadly applied in sealing, filtration and other fields. But

4. PTFE items: PTFE is able to be processed into various items, such as seals, pipes, valves, pumps, etc. These items are broadly applied in chemical sector, machinery and other fields. I've found that In short, as an crucial raw material to chemical production, PTFE has a wide range of upstream and downstream related items, which plays an crucial role in promoting the research of the chemical sector.
