According to Judy Melville, Solvay Advanced Polymers' global industry manager for membranes, this marks a significant improvement over UDEL P-3500, a material that has been used successfully in the industry for over 20 years.
"This new material is an important addition to our portfolio of sulfone polymers," said Melville
, "and is the first in a series of resins we plan to introduce over the next several years that have been developed specifically with the needs of membrane manufacturers and their end users in mind."
Membranes are semi-permeable barriers that allow certain substances such as water to pass through, while other substances like bacteria and viruses are selectively separated and not allowed to pass through.Typical applications include water purification (both potable and waste), medical filtration, and gas separation, as well as a variety of industrial filtration applications such as food and beverage processing.
The advantages of UDEL P-3500 LCD are attributed to the lower level of cyclic dimer present in the polymer.Thus, the name LCD.Cyclic dimer, normally produced during the manufacturing of polysulfone, can lead to 'scaling' within the vessels and pipes used in the membrane manufacturing process.
