Udel® polysulfone

Udel polysulfone (PSU) is a rigid, high-strength, semi-tough thermoplastic that has a heat deflection temperature of 345°F (174°C), and maintains its properties over a wide temperature range. Udel excels in many fluid-handling applications and has over 10 years of success replacing brass in pressurized hot water plumbing applications.
