What is polysulfone material?
PSU (polysulfone) is a high temperature, amber colored, semi-transparent plastic material with good mechanical properties. Polysulfone is resistant to degradation from hot water and steam and it is often used in medical and food preparation applications where repeated sterilization is required.
What is the density of polysulfone?
1.24
8.2. 2 Polysulfones Properties
| Property | Units | Polysulfone (PSU) |
|---|---|---|
| Density | g/cc | 1.24 |
| Light transmittance | % | 70 |
| Water absorption at equilibrium | % | 0.5 |
| Glass transition temperature | °C | 185 |
Can you machine polysulfone?
Machining PSU (Polysulfone)
AIP uses computer controlled annealing ovens for the highest quality precision machining of PSU and other thermoplastics. Non-aromatic, water-soluble coolants are most suitable for ideal surface finishes and close tolerances. These include pressurized air and spray mists.
What is polysulfone membrane?
Polysulfone is an organic polymer widely used due to the chemical and thermal stability provided to the membrane [2]. Polymeric membranes can be obtained by applying phase separation process.
What is polysulfone used for?
Polysulfone allows easy manufacturing of membranes, with reproducible properties and controllable size of pores down to 40 nanometers. Such membranes can be used in applications like hemodialysis, waste water recovery, food and beverage processing, and gas separation.
Is polysulfone soluble in water?
In many commercial membranes polysulfone (PSf) is used as support layer. However, this polymer dissolves in a liquid water/toluene mixture.
What is Udel resin?
Udel® PSU resins are amorphous sulfone polymers and offer many desirable characteristics, such as resistance to hydrolysis, thermal stability, retention of mechanical properties at elevated temperatures, clarity, and transparency.
Is polysulfone hydrophobic or hydrophilic?
The inherent hydrophobic nature of polysulfone is often cited as disadvantage in using this polymer as a membrane material. Hydrophilicity can be imparted into polysulfone by the addition of hydrophilic functional polymer groups [1].
How do you dissolve polysulfone?
It can very well dissolve in N-Methyl-2-pyrrolidone (NMP). You have to use DMF/Acetone (30:70).
Is polyethersulfone the same as polysulfone?
The key difference between polysulfone and polyethersulfone is that a polysulfone is a group of thermoplastic polymers consisting of repeating units with a sulfone group, whereas a polyethersulfone is a group of thermoplastic polymers consisting of the subunit aryl-SO2-aryl pattern.
Is polysulfone a thermoplastic?
Polysulfones, also called polyaryl sulfones, are a class of engineering polymers with high thermal, oxidative and hydrolytic stabilitiy. They are amorphous, transparent thermoplastics that can be molded, extruded, or thermoformed into a wide variety of shapes.
How do you make polysulfone?
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.
What is PES polymer?
Polyethersulfone (PES)
Polyethersulfone (PES) is an amorphous, transparent, and pale amber high-performance thermoplastic. It is the most temperature resistant, transparent commercially available thermoplastic resin. It is a high temperature engineering thermoplastic with high stability and mechanical strength.
Does polysulfone have BPA?
Polysulfone does contain traces of Bisphenol A (BPA) by nature of its monomer building block.
