PSU / PES – Polysulfones

PSU / PES: Ultrasound, Udel

Typical applications

Medicine and nursing

Due to their resistance to autoclaving (steam sterilization), they are ideal for:

• Medical instruments: surgical trays, tool handles and device housings.
• Dialyzers: key components (hollow fibers and housings) for artificial kidneys.
• Anesthesia equipment: breathing masks, valves and connectors.

Water filtration and purification

Polysulfones have excellent porosity and chemical resistance, so they are used for:

• Ultrafiltration membranes: drinking water purification and wastewater treatment.
• Biotechnological filters: plasma separation and filtration in pharmaceutical manufacturing.

Food industry and catering

The materials meet strict conditions for food contact (FDA standards):

• Catering containers: food containers suitable for microwaves and steam baths.
• Dosing systems: parts of coffee machines, dispensing devices and milking equipment.

Automotive and aerospace industries

They are used in places where high temperatures and aggressive liquids are present:

• Electrical connections: fuse boxes, switches and relays under the hood.
• Fuel components: fuel pump parts and oil systems.
• Aircraft interiors: window trims and seat parts (due to the low level of smoke and toxic gas release in the event of a fire).

Electrical engineering and electronics

• Printed circuit boards: substrates for high-frequency circuits.
• Insulation parts: coil holders, connectors and battery housings.
