What is polyethersulfone ultrafiltration membrane?
Polyethersulfone (PES) could be used to prepare ultrafiltration membranes, because it has high glass transition temperature at 230°C and superior mechanical strength. MS® PES membranes (MS®SUF) are designed for high protein rejection and extended life with excellent chemical and temperature resistance.
Why is polyethersulfone used for membranes?
Polyethersulfone (PES), as shown in Figure 1, is considered one of the well-known polymeric material to be used to make ultrafiltration (UF), microfiltration (MF), and gas separation membranes since it provides unique properties such as outstanding thermal, mechanical, hydrolytic strength in both hot and wet …
How is polyethersulfone made?
The simplest polysulfone poly(phenylene sulfone), known as early as 1960, is produced in a Friedel-Crafts reaction from benzenesulfonyl chloride: n C6H5SO2Cl → (C6H4SO2)n + n HCl. With a melting point over 500 °C, the product is difficult to process.
Is polyethersulfone hydrophilic or hydrophobic?
Polyethersulfone membrane are generally hydrophilic.
What is polyethersulfone used for?
Unreinforced grades are used in high-temperature electrical applications, bakery oven windows, and medical components. The reinforced grades are incorporated in radones, airplace components and automotive parts. It can be processed on conventional injection molding, blow molding, extrusion and thermoforming equipment.
What is PES filter?
For General Filtration Applications PES is an inherently hydrophilic membrane that wets out quickly and completely resulting in fast filtration with superior flow rates and high throughputs. PES membrane is also extremely low protein binding minimizing the likelihood of target analyte binding.
What is PES material?
Polyethersulfone (PES or PESU) is relatively a new class of polymer and known since 1972 when first introduced by ICI. This high-temperature engineering thermoplastic has good transparency and flame resistance, and it is one of the lowest smoke-emitting materials available.
What is PES plastic?
PES plastic is a high temperature engineering thermoplastic with outstanding tolerance to temperatures for long periods. PES polymer offers high mechanical strength and rigidity, coupled with relatively low notch sensitivity. In addition, polyethersulfone offers good chemical compatibility and hydrolysis resistance.
Is polyethersulfone hydrophilic?
For General Filtration Applications PES is an inherently hydrophilic membrane that wets out quickly and completely resulting in fast filtration with superior flow rates and high throughputs. Polyethersulfone membrane is compatible with EtO, gamma irradiation, and autoclave methods of sterilization.
How do I choose a membrane filter?
Step 1: Match your application with the appropriate pore size. Step 2: Select the membrane and housing material for your application. Step 3: Select the correct membrane area to optimize flow rate and throughput. Step 4: Choose the best filter design for your application.
How is the ultrafiltration membrane of polyethersulfone prepared?
In this work, polyethersulfone (PES) ultrafiltration (UF) composite membrane incorporated with lamellar GO and hollow HNTs were prepared via non-solvent induced phase separation (NIPS) process, respectively.
Which is the best membrane for UF ultrafiltration?
AMI® polyethersulfone (PES) spiral wound ultrafiltration (UF) membrane elements provide removal of fine particles from aqueous solutions to a molecular weight cut-off (MWCO) of 10,000. AMI membrane elements are among the finest in the industry.
What are the properties of PSU polyethersulfone?
In 1998, PSU polyethersulfone (PES), and polyphenylethersulfone (PPSU) contributed more than 2.0×104 tyr −1 to the worldwide market of amorphous HT thermoplastics. Important properties are: good mechanical behavior between −50 °C and 180 °C; high dimensional stability; transparency; and self-extinguishing.
Why do polyethersulfone polymers need to be filled?
However, these polymers suffer from poor UV light stability, and thus must be filled for outdoor uses, as well as decreased notch impact strength, which is improved for PPSU.
