A polyethersulfone is a thermoplastic with excellent mechanical properties and a low density. It is transparent, stiff, and resistant to heat, corrosion, and decomposition. The chemical and physical properties of this polymer are excellent, making it ideal for a variety of applications. The resins made from polyethersulfone are used for wire coatings, household items, and automotive components. This type of material is often used in medical devices, such as implantable stents, and are also used for other medical equipment.
One of the advantages of using Polyethersulfone as a filter material is its high hydrophilicity. Due to its high ionic strength, it can withstand temperatures up to 180 degrees Celsius (210 degrees Fahrenheit). Moreover, it has excellent chemical and thermal stability. It can withstand continuous stress of 3000 psi at 20 degrees Celsius, resulting in a strain of less than 1%. In addition, it is highly resistant to acids and other types of chemicals. This means it can withstand repeated sterilization and will not degrade.
Along with its high resistance to aqueous mineral acids, Polyethersulfone is also fairly resistant to many non-polar solvents. Moreover, polysulfone can be processed using injection molding or extrusion. The material's dimensional tolerances can be kept to a minimum. For this purpose, Ensinger supplies Polyethersulfone in both sheet and rod form. Polyethersulfone has several advantages. Among other features, it is resistant to a broad range of temperatures and has low protein binding. It can be used in pharmaceutical filtration, medical devices, and household products. Despite the high cost of manufacturing, polyethersulfone is very easy to process, making it an inexpensive and highly useful material for a variety of applications. So, it is easy to understand why this material is an excellent choice for such projects. Another advantage of polyethersulfone is its resistance to aqueous mineral acids. It is also relatively resistant to many non-polar solvents. Besides being highly resistant to aqueous acid, polysulfonesulfone can be processed by conventional thermoplastic methods. Recently in October 2019, Solvay started the operation of its new Veradel PESU (polyethersylfone) line at its plant in Panoli, India.
