Sustason PSU (polysulfone) is a semi-transparent amorphous thermoplastic with an amber tint. It is a logical progression from standard transparent plastics such as polycarbonate when improved chemical or higher temperature resistance is required by an application. Sustason PSU can be used continuously in hot water and steam sterilization and has excellent chemical resistance to acidic salt solutions.
