Sulfone polymers
Got a tough job? Our sulfone polymers, polysulfone (PSU), polyethersulfone (PESU), and polyphenylsulfone (PPSU), can take it. These amorphous polymers are inherently transparent and stay strong in some of the toughest environments. They readily withstand exposure to water, chemicals and heat – handling a broad range of end-use temperatures from -40°F to 400°F (-40°C to 204°C). High-clarity, colored and glass fiber-reinforced grades are available.
