Udel® P-3500 LCD MB

Udel polysulfone is a thermoplastic with high toughness, high rigidity and high strength, and has excellent hydrolysis resistance. Udel P-3500 LCD MB series polymers are especially suitable for solvent-based process to produce porous hollow fibers and flat film. These high molecular weight polymers are used in various membrane filtration products, such as renal dialysis, water treatment, biological treatment, food and beverage processing, and industrial gas separation. Udel polysulfone polymer has many properties required by the membrane industry, such as excellent mechanical properties, stability at 2 ~ 132PH, excellent corrosion resistance and good resistance to medium concentration chlorine. It is a low level of precipitation, insoluble material, suitable for drinking water and products in contact with food. Steam, ethylene oxide and electron beam radiation can be used for disinfection. Udel P-3500 LCD MB series polymers contain a series of grades with narrow molecular weight distribution, as shown in the following figure. The level of ring dimer of each brand is lower than that of the original P-3500NT 11 brand. This is very important in solution treatment, such as membrane production process, because it improves the solution stability of spinning dope and reduces scaling of equipment.
