Sulfone polymers are amorphous high-heat polymers that retain their mechanical strength in some of the toughest environments. Unfilled grades offer good ductility and are available in a range of transparent colors.

Udel polysulfone (PSU) offers exceptional dimensional and hydrolytic stability and has an HDT of 174°C (345°F). Mindel modified PSU provides specific advantages over Udel PSU, such as superior electrical properties. Veradel polyethersulfone (PESU) offers a high HDT of 204°C (399°F) and better chemical resistance than Udel resins.

Key Features

• High glass transition temperatures up to 220°C 
• Strength and toughness at elevated temperature
• Excellent hydrolytic stability
• Good electrical insulation properties
• High elongation for good ductility
