Polysulfone

2. • Polysulfone describes a family of thermoplastic polymers.
• These polymers are known for their toughness and stability at
…high temperature.
• Polysulfone is resistant to degradation from hot water and steam.
• Polysulfone is used in applications requiring good high temp.
..resistance such as coffee carafes, piping, sterilizing equipments,
..and microwave oven cookware.

5. • Thermally stable
• High strength, stiffness and toughness
• good flame retardancy characteristics and very low smoke
..release characteristics
• Low creep
• Exhibit good dielectric properties
• High dimensional stability
• Resistant to the Chemicals
• Tg is 185˚C
• Initial degradation starts at 100-200˚C, decomposition
..occurs at high temperature
• These resins are also highly resistant to degradation by
...gamma or electron beam radiation.

6. •They are attacked by polar solvents such as ketones, chlorinated
hydrocarbons, and aromatic hydrocarbons.
• Increased cost
• Poor weather ability
• Subject to the stress cracking
• Poor resistant to UV light
It has many applications in:
• Polysulfone is also used in electrical applications for connectors,
switches, and circuit boards
• Polysulfone membrane fabrication that is used for drinking water
purification.
• Used in aerospace technology
• Chemical and food processing equipment
• Various pumping & home appliance items

7. • Nanocomposites of polysulfone (PSF)-
...graphene oxide (GO) were prepared by
classical phase inversion method.
• TEM and X-ray diffraction analysis indicated a
..good compatibility and excellent dispersability
..with PSF matrix for the low GO content (0.25,
0.5 and 1 wt.%) composites.
• It was observed that GO dispersion was
..reasonably homogeneous for the composite
..with 2 wt.% GO.
• The mechanical properties of the prepared
..materials were found to be greatly enhanced
..by the addition of GO for some compositions.

8. • The thermogravimetrical
…investigation demonstrated
…considerable improvements in
…thermal stability for the composite
…with low GO content.

9. • Due to high cost it is not being used.in domestic level
..extensively but is using in industrial level like aerospace
..industries etc.
• It’s now being used in new grades (composite) made with
..glass fibers and having higher strength than older ones.
• Due to it’s high thermal stability it is mostly used where high
..thermal stability is required e.g. in microwave oven cookware
..etc.
