Aplikasi
VDF minangka monomer sing ngemot fluorine sing penting, bisa nyiyapake resin fluorida polyvinylidene (PVDF) liwat polimerisasi tunggal, lan nyiapake fluororub F26 liwat polimerisasi karo perfluoropropene, utawa fluororub F246 kanthi polimerisasi karo tetrafluoroethylene lan perfluoropropene. minangka pestisida lan pelarut khusus.
Paket, Transportasi lan Panyimpenan
1. Vinylidene fluoride (VDF) kudu disimpen ing tank karo interlayer kang diisi karo uyah chilled, tetep sumber saline chilled tanpa breakage.
2. Vinylidene fluoride (VDF) dilarang ngisi menyang silinder baja.Yen mbutuhake silinder baja kanggo kemasan, kudu nggunakake silinder baja khusus sing digawe saka bahan tahan suhu rendah.
3 .Silinder baja diisi karo vinylidene fluoride (VDF) kudu dilengkapi tutup safety sing tightly ngaco ing transportasi, tetep saka geni.Should nggunakke piranti sunshade nalika diangkut ing mangsa panas, nglindhungi saka cahya srengenge.Silinder baja kudu dimuat lan dibongkar kanthi entheng, supaya ora ana geter lan tabrakan.
