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.

The high thermal stability is provided by the diphenylene sulfone group. It imparts high strength, high resistance to oxidation, and excellent flame retardancy but makes the polymer rigid. Flexibility in the backbone of the polymer is provided by ether linkages. These ether linkages also add to the thermal stability. Many commercial grades can tolerate high temperatures for a long period of time. Some grades, like polyphenylsulfone, are extremely tough and have very high impact strength, comparable to polycarbonate.

Polysulfones are highly resistant to aqueous mineral acids, bases, and oxidizing agents and are fairly resistant to many non-polar solvents. However, polysulfones are not resistant to low polar solvents, such as esters, ketones, aromatic and chlorinated hydrocarbons.

APPLICATIONS

Polysulfones are chemical inert, highly biocompatible, and can be sterilized. These properties make them highly suitable for medical and food/beverage contact applications. Many grades can withstand long term exposure to hot chlorinated water and have received approval for food contact and drinking water.

Polysulfones are an excellent choice for many machine and appliance parts that are exposed to high temperatures and/or corrosive media. Examples include internal components of coffee machines, battery containers, and printer cartridges. Polysulfones are also used in the automotive and aerospace industries for applications where superior thermal and mechanical properties relative to conventional resins are required.
