Material Notes:
Udel polysulfone is a tough, rigid, high-strength thermoplastic with outstanding hydrolytic resistance. Udel P-3500 LCD MB series polymers are particularly well suited for the fabrication of porous hollow fiber and flat sheet membranes using a solvent-based process. These high molecular weight polymers are used in a variety of membrane filtration applications, such as renal dialysis, water treatment, bio-processing, food and beverage processing, and industrial gas separation. Udel polysulfone polymers possess a number of attributes that are valued by the membrane industry, including excellent mechanical properties, stability at pH levels from 2-13, excellent resistance to caustic and good resistance to moderate concentrations of chlorine. They feature low levels of extractible and insoluble materials making them suitable for drinking water and food contact uses. They may be sterilized using steam, ethylene oxide and e-beam radiation. Udel P-3500 LCD MB series polymers are available in various narrow molecular weight range grades, as shown below. Each grade features reduced levels of cyclic dimer compared to the previous grade, P-3500 NT 11. This can be important in solution processing applications such as membrane production, as it leads to improved dope solution stability and reduced equipment fouling. The Udel P-3500 LCD MB series polymers are soluble in commercially available, water-miscible, dipolar, aprotic solvents, such as dimethylacetamide (DMAC), dimethylformamide (DMF), and N-methylpyrrolidone (NMP). These materials offer membrane producers very good control of pore size and pore size distribution, high membrane strength, and good film-forming properties.Injection Notes: UDEL P-3500 polysulfones may be dried before preparing solutions. Pellets can be dried in a circulating hot air oven, by spreading the pellets on trays to a 1-2 inch depth and drying for 3.5 hours at 257 to 325°F (135 to 163°C).Information provided by Solvay Specialty Polymers.
