Ofluorine 904 PVDF has good solubility in some special solvent, which is good raw materials

for PVDF membranes.
Ofluorine 904 PVDF as raw materials, the PVDF membranes has excellent mechanical strengt

h and flexibility. It can not be eroded by acid, alkali, strong oxidant, halogens. Good durabili

ty to aliphatic hydrocarbons, aromatic hydrocarbons, alcohol, aldehyde etc. In the work of hy

drochloric acid, nitric acid, sulfuric acid, dilute alkali liquor, dense alkali liquor(40%) and 100d

eg.C, which keep stable.
Others, 904 PVDF finished products has the properties of gamma-Ray resistant, UV(ultraviolet)

resistant, and stability in wide temperature range.
