Polysulfone, also known as polyarylsulfone, is an engineering polymer with high thermal, oxidative, and hydrolytic stability. Amorphous, transparent thermoplastics can be molded, extruded, or heat-pressed into various shapes. The diphenylene sulfone group provides high thermal stability. It gives high strength, high oxidation resistance, and excellent flame resistance but causes the polymer to harden. Ether bonds offer flexibility in the polymer backbone. These ether bonds also add thermal stability. Many commercial grades can withstand high temperatures for a long time. Some, such as polyphenylsulfone, are extremely stiff and have high impact resistance, comparable to polycarbonate.
Polysulfone is resistant to mineral acids, bases, oxidizing agents, and many non-polar solvents. However, polysulfones are unstable to weakly polar solvents, such as esters, ketones, and aromatic and chlorinated hydrocarbons. Typical grades with good melt stability allow fabrication using conventional thermoplastic processing methods, including injection molding, extrusion, and heat pressing. Due to the low mold shrinkage, polyethersulfone can be quickly formed into small parts with very tight dimensional tolerances.
Usage of Polysulfone
Polysulfone is chemically inert, highly biocompatible, and can be disinfected. These properties make them ideal for medical applications and food/beverage contact. Many can withstand prolonged exposure to chlorinated hot water and are approved for contact with food and drinking water. Well, polysulfone is an excellent choice for many machine and equipment parts exposed to high temperatures and corrosive media. Examples include the internals of the coffee machine, the battery case, and the printer cartridge. It is also applied in the automotive and aerospace industries for diverse applications requiring superior mechanical and thermal properties compared to conventional plastics. Some modified polysulfones have high gas permeability and have been used as membrane materials for gas separation.

Technical data sheet & Chemical Formula
Polysulfone is a family of high-performance thermoplastics. These polymers are important due to their toughness and high-temperature stability. Technically used polysulfones consist of an aryl-SO2-aryl subunit. Because of the very high cost of obtaining and processing polysulfone raw materials, these materials are used in special applications. They are often used as superior substitutes for polycarbonates. The chemical formula is C6H5SO2Cl → (C6H4SO2)n + n HCl.

Packing of Polysulfone
Polysulfone is usually packed in 25 to 500 kg PP or woven bags.
Safety & warning & transportation of Polysulfone
Polysulfone was found to be non-hazardous. Take them out into the sun; If their condition worsens, you should consult a doctor. In other words, see your doctor if you feel the need. Instead of using ice to cool the burn, stand under fast-moving water. If the chemical gets on the skin, DO NOT try to wash it off with water. Damage to surrounding tissue is a real possibility during removal. Check-in now. Safe and functional emergency showers should always be easily accessible. One of the main ways to take care of both eyes is to spray them with water from time to time. Don’t stop washing after the first second, and keep your contacts on while you do. If symptoms persist, see a doctor, preferably an ophthalmologist. Get medical help right away if swallowed. It may cause constipation. You don’t have to take any special steps for transporting this compound.
