• Broad temperature range capability
• Good thermal and electrical insulation characteristics
• Hydrolysis resistant
• Radiation stability

PSU 1000 Polysulfone is hydrolysis resistant for continuous use in hot water and steam at temperatures up to 300°F. Its flame resistance is UL 94-V-0 at 1/4" thickness (6.35mm) and UL 94-V-2 at 1/8" thickness (3.175mm).

PSU 1000 Polysulfone offers high chemical resistance to acidic and salt solutions, and good resistance to detergents, hot water and steam. In addition, polysulfone has excellent radiation stability, and offers low ionic impurity levels. PSU 1000 Polysulfone often replaces polycarbonate when higher temperatures, improved chemical resistance or autoclavability is required (See Figure 14). It is commonly used for analytical instrumentation, medical devices and semiconductor process equipment components

Food-grade PSU 1000 Polysulfone and custom colors can be special ordered. Only food-grade PSU 1000 is FDA, NSF, 3A-Dairy and USP Class VI compliant.

Proven Applications:

Manifolds Manifolds machined from PSU 1000 Polysulfone plate optically transparent, able to be sterilized by radiation, and resist cracking from environmental stresses. (Prior material: Acrylic)
Distributor Valves In the poultry industry, PSU 1000 Polysulfone parts used on processing lines offer chemical resistance and minimal expansion rates. (Prior material: Stainless Steel)
Medical Equipment Components Parts machined from PSU 1000 Polysulfone compatible with blood on dialysis equipment and can endure repeated autoclaving cycles. (Prior assembly: Stainless Steel)
Steam Cleaning Equipment Inserts Inserts made of PSU 1000 Polysulfone reduce chemical attack on the nylon distribution block in hot water and steam cleaning equipment. (Prior material: Nylon)
Engineering Notes Polysulfone is not a wear material and may stress craze under high pressures in certain chemical environments.
