Polysulfone Specifications

Description

Made from Polysulfone resin, these stock shapes remain stable, resisting creep and deformation under continuous load and elevated temperatures. They have high tensile strength and, as temperatures increase, flexural modulus remains high. Polysulfone products will withstand exposure to soap, detergent solutions and some hydrocarbon oils, even at elevated temperatures under moderate stress levels.

Applications

Float switches • Membrane cartridge filter system • Solenoid valve body • Dairy connectors

Advantages of Polysulfone

Dimensionally stable • Easily machined • FDA compliant • Transparent grades available • Excellent mechanical and electrical properties • Steam resistant • Low outgassing levels

Manufacturing Capabilities

Rod: 3/16” to 6” diameter • Sheet: .035” to 3/16” thick • Slab: 1/4” to 4” thick • Film: .001” to .029” thick

Color/Grades

Light Amber • (custom colors available)
