Product Description
Polyvinylidene fluoride (PVDF DS204/DS204B) powder is the homopolymer of vinylidene fluoride, which have good tensile properties and toughness. It has good solubility in some solvents, suitable to make hollow fiber and flat sheet Membranes. This kind of membrane can not be corroded by acid, alkali, strong oxidizer and halogen. It has good chemical resistance in aliphatic hydrocabon, aromatic hydrocarbons, aldehydes and some other organic solvents.
Conformable with Q/DYS 014-2013
