  • Excellent resistance to water up to 100 °C and to low-pressure steam up to 135 °C
  • Strong resistance to weak acids and alkalis
  • Sterilization possible with gas, steam, gamma or X-rays

Standard Compliant

  • Fulfills requirements of the European Pharmacopoeia 3.1.9.
  • Fulfills requirements of FDA regulation 21CFR, § 177.2600.


  • ISO 10993 tested
  • USP class VI tested
  • Pyrogenicity tested in accordance with European Pharmacopoeia

One step ahead of other silicone tubing

Patented & unique: Low Tack Surface 

RAUMEDIC's SILMOTION biopharma silicone tubing features the patented Low Tack surface treatment.

After the tubing has been extruded, a unique coating is applied to the exterior surface of the SIL fluid handling tubing by a specialized Low Tack method.

4 ways customers benefit from RAUMEDIC's patented Low Tack surface treatment:

1. Enhanced pumping properties
  • Lower gliding force
  • Reduced strain at the point of contact with the pump.
  • Increased lifespan of tubing due to reduced wear and decreased material abrasion
2. Better handling
  • Better sliding properties than untreated pharma tubing
  • Less sticky surface - ideal for secondary processing, assembly and packaging.
3. Fewer impurities
  • Decreased adhesion of particles on the tubing’s surface
  • Significant reduction of possible impurities
4. Inkjet printable
  • Printable tubing – unlike other common silicone tubing in the market
  • Cleaner and safer than roller printing – or other methods
