产品说明

Ofluorine 904 PVDF Powder for water UF membranes has good solubility in some special solvent, which is good raw materials for PVDF UF membranes.

Ofluorine 904 PVDF as raw materials, the PVDF membranes has excellent mechanical strength and flexibility. It can not be eroded by acid, alkali, strong oxidant, halogens. Good durability to aliphatic hydrocarbons, aromatic hydrocarbons, alcohol, aldehyde etc. In the work of hydrochloric acid, nitric acid, sulfuric acid, dilute alkali liquor, dense alkali liquor(40%) and 100°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.
