With our extruders, tubes and pipes are manufactured for medical applications.

Medical tubes made of PTFE (polytetrafluoroethylene) offer some clear advantages that make them particularly suitable for many applications:

1. High chemical resistance

PTFE reacts with virtually no chemicals. This is important for:

• aggressive medications
• disinfectants
• laboratory media

-> The tube remains stable and does not release any substances.

2. Very good biocompatibility

PTFE is well tolerated by the body:

• barely attacked by the immune system
• ideal for catheter or implant applications

3. Extremely smooth surface

• reduces friction → facilitates insertion (e.g., in catheters)
• prevents deposits of blood, proteins, or bacteria

-> Lower risk of blockages or infections.

4. Temperature resistance

• withstands both very high and very low temperatures
• can be easily sterilized (e.g., autoclaving)

5. Low adhesion (non-stick effect)

• liquids hardly adhere
• facilitates cleaning and prevents residues

6. High electrical insulation capability

Relevant for certain medical devices or sensor cables.

In short:

PTFE tubes are ideal when purity, chemical stability, and safety are crucial – for example, in infusion technology, laboratory medicine, or special catheters.

With R&K extruders, tubes are manufactured by leading medical manufacturers.
