Water Film Grade PVDF Resin
1. Product Introduction
PVDF Resin is used to prepare microfiltration membrane and ultrafiltration membrane because of excellent chemical resistance,mechanical toughness and durability Since the PVDF resin can be dissolved in conventional processing solvents and has good formability property and big bulk density,it can satisfy both the NIPs and TIPs at the same time.
We have a range of medium resistant PVDF resins for customers to choose from. 2212 is a suspension resin with relatively low molecular weight.small viscosity and good solubility.It is a trial product with large flux.The molecular weight and viscosity of 2215 are in the middle.It can be used and supported to homogenize two systems.2220 has high molecular weight and high viscosity,which is used for high-strength products.
