 Polyethersulfones are highly resilient thermoplastic plastics. Materials made of polyethersulfones are transparent or slightly transparent (high light transmission and refractive index), resistant to hydrolysis, and provide excellent chemical resistance to mineral lubricants, aliphatic hydrocarbons, acids and alkalis.
Polyethersulfone
The thermoplastic polyethersulfone has a melting range or glass transition temperature of approximately 220°C and can be processed to form a finished product with up to 30% inorganic fillers, fibreglass or carbon fibres in an extrusion (extruded profiles) or injection moulding process. Due to their optimum electrical insulating properties, polyethersulfones have applications in the electronics and automobile industries. Polyethersulfones are also used in the medical sector, the food sector (membrane technology), as well as in aircraft cabins.
