VDF
Vinylidene fluoride (VDF) normaliter hyalina, nontoxica, et flammabilis, et tenuem aetheris odorem habet. Est monomerorum fluororum summi polymerorum magni momenti cum olefini genere communi, et capax polymerizing et copolymerizing. Ad praeparationem adhibetur. of monomer or polymer and synthesis of media.

Applicationem
VDF tam magni momenti fluorini continentis monomerorum, potest per singula polymerizationem (PVDF) per polymerizationem praeparare, et F26 fluororubber per polymerizing cum perfluoropropene, seu F246 fluororubber polymerizing cum tetrafluoroethylene et perfluoropropene. quasi pesticide et speciali solvent.

1.Vinylidene fluoride (VDF) in piscina reponendum est cum interpositorio quod salinum frigidum oneratum est, servato salinarum frigidorum copia sine fractura.
2.Vinylidene fluoride (VDF) vetitum est in cylindros ferreos incurrens.Si ferro cylindri ad sarcinam indigeant, cylindris praecipuis chalybeis adhibitis, ex humili temperatura resistentiae materiis factis.
3 .Steel cylindrici cum vinylidene fluoride (VDF) instructi debent galeros tutos in vecturae arcte congredi, ab igne custodiendos. Utitur umbracula fabrica in aestate transportata, eam a nuditate ad solem protegens.Cylindri ferrei debent leviter onerari et exonerare, a vibratione et collisione custodiendo.
