How PVDF is Synthesized
PVDF is produced through the free-radical polymerization of vinylidene fluoride (CH2=CF2) in a controlled environment. The process involves:
- Monomer Preparation: Vinylidene fluoride gas is synthesized from fluorinated precursors.
- Polymerization: Conducted in suspension or emulsion under high pressure and temperature, often in the presence of a catalyst.
- Processing: The resulting polymer is processed into powder, granules, films, or sheets for various applications.
Symb ChemTech ensures high-purity PVDF through advanced manufacturing techniques, delivering consistent quality for your needs.
