PVDF DS204
Product Description
Polyvinylidene fluoride (PVDF) powder (DS204) is a kind of homopolymer powder polymerized by vinylidene fluooride. As one of the thermosplastic fluorine resin, it has excellent mechanical strength and toughness .good resistance to most of the chemical medium. PVDF DS204 has good solubility in some solvent, suitable to make PVDF MEMBRANE THROUGH DISSOLVING AND CURTAIN COATING PROCESS TECHNOLOGY. .At room temperature ,this membrane materials can not be corroded by acid ,alkali, strong oxidizer and halogen ,and has good chemical stable performance in the aliphatic hydrocarbon .aromatic hydrocarbons,aldehydes, alcohols and some other organic solvent. In the hydrochloric acid ,nitric acid , sulfruic acid and thin and thick (40%) lye and above 100°c Temperature ,the basic performance is unchanged.
