What is Polyethersulfone Membrane?
What is Polyethersulfone Membrane?
Polyethersulfone (PES) membrane for aqueous solutions provides removal of fine particles, bacteria, and fungi making it a versatile membrane for applications such as sample preparation, sterile filtration and infusion therapy.
What is Supor membrane?
Supor® hydrophilic polyethersulfone membranes offer higher fluid flow rates, lower protein binding, lower extractables, and greater strength than other cellulosic (acetate, nitrate) membranes.
How do you dry polyethersulfone?
The maximum recommended drying temperature is 163 °C (325 °F) for Udel® polysulfone (PSU) and 177 °C (350 °F) for Radel® polyphenylsulfone (PPSU), Veradel® polyethersulfone (PESU), and Acudel® modified PPSU. Sulfone polymers must be dried for optimum molding results.
What is Pan membrane?
Poly(acrylonitrile) (PAN) is a polymer that is widely used as an ultrafiltration membrane in aqueous applications, because it is more hydrophilic than most organic polymers and has sufficient chemical resistance to remain stable in aggressive cleaning environments [105] .
What is a supor filter?
Description. High Flow Rate Membrane Optimized for Biological, Pharmaceutical, and Sterilizing Filtration Requirements. Fast filtration with superior flow rates and high throughputs. Low protein binding and extensive drug compatibility for critical.
What are the physical properties of unfilled polyethersulfone?
DISCLAIMER Unfilled Polyethersulfone (PES) Thermo-Physical Properties PROPERTY UNIT VALUE / RANGE Melting Point °C 227 – 238 Density g mL-1 1.37 Coefficient of Thermal Expansion x 10-5 cm / (cm °C) 4.9 – 5.7 Heat Deflection Temperature, 0.5 MPa
What is the molecular formula of polyethersulfone?
Molecular Structure of Polyethersulfone Molecular Formula: (C 12 H 8 O 3 S) n An amorphous polymer which possesses bonds of high thermal and oxidative stability
What is polyethersulfone (PES)?
Polyethersulfone (PES) is an amorphous polymer and a high-temperature engineering thermoplastic. Even though PES has high-temperature performance, it can be processed on conventional plastics processing equipment. Its chemical structure is shown in Fig. 11.14. Its CAS number is 25608-63-3.
What is the transition temperature of polyether sulfone?
Polyether sulfone has a glass transition temperature news 225°C and is dimensionally stable over a wide temperature range. It has a heat-deflection temperature of 203°C at 264 psi. Certain grades are capable of operating at temperatures above 200°C. It has outstanding long-term resistance to creep at temperatures up to 150°C.
