PPSU pipes are high-performance thermoplastic pipes made by precision extrusion of polyphenylene sulfone resin. As the most comprehensive material in the polysulfone family, PPSU pipes have outstanding performance in high temperature steam sterilization resistance, impact toughness, and chemical corrosion resistance, making them an ideal alternative to metal pipes and stainless steel fittings in the high-end field
The core difference between PEEK/PPS pipes:
High toughness: PPSU’s impact strength far exceeds PPS, and even surpasses PEEK, making it less prone to brittle cracking
Steam sterilization resistance: It can repeatedly withstand high-pressure steam sterilization at 134 ℃ and is the preferred material in the field of medical devices
Transparency: PPSU is semi transparent amber color, making it easy to observe the fluid state inside the tube (PEEK/PPS are both opaque)
Cost effectiveness: The performance is close to PEEK, but the price is more advantageous
Main application areas
- Medical devices (core applications)
PPSU pipes are widely used in the medical field due to their ability to withstand repeated steam sterilization and excellent biocompatibility
Surgical instruments: minimally invasive surgical catheters, endoscopic channels, surgical instrument handles
Medical equipment piping: infusion system, dialysis equipment piping, ventilator piping
Medical connectors: pipe fittings, quick couplings - Food and beverage industry
PPSU material complies with FDA and EU food contact regulations and is used for:
Filtration system: cross flow membrane tube, reverse osmosis, ultrafiltration/microfiltration components
Drinking water system: water treatment pipeline, beverage distribution pipeline
Food processing equipment: sanitary grade fittings, joints
The semi transparent property of PPSU can quickly detect deposits and pollutants inside the pipe, which is an advantage that stainless steel pipes do not have
Chemical and Pharmaceutical Industry
PPSU has excellent chemical corrosion resistance and can maintain stable performance even at high temperatures:
Chemical conveying pipeline: acid and alkali resistant, solvent resistant
Pharmaceutical equipment pipeline: meets GMP requirements and can be repeatedly cleaned and sterilized
Laboratory Fluid System - Water heating and bathroom
PPSU has excellent hydrolysis resistance and hot water environment stability, and is used for:
Drinking water fittings: PPSU pipe fittings fully comply with European MOCA drinking water requirements
Hot water system pipeline: can withstand high temperature hot water for a long time
Thermal cycling system: Strong resistance to thermal cycling and pressure fluctuations
