Choice material for filtration applications
Purity of product and performance require higher-performance filtration materials.
Resistant to many chemicals, the molecular structure of Ultrason® makes it particularly suitable for many membrane applications—from the medical dialysis to beverage production. Ultrason membranes can even filter out gases.
Marketed in a powder or porous flake form for faster dissolution, Ultrason E 6020 P has a high molecular weight, specially developed for membrane manufacturers. However, the real advantages of using Ultrason E can be seen when compared to other membrane materials.
Manufacturers and end-users have noted that PES gives: better membrane pore size control; a stronger membrane that is more resistant to chemicals, steam sterilization and damage (tearing etc.); better temperature resistance because Tg is 40 °C higher than polysulfone; and a membrane with better blood compatibility
