Anti-friction fluorination

Many components made of elastomers such as NBR, HNBR, EPDM, silicone and other rubbers have a dull surface. These are often sticky and don’t slide well across other surfaces. This may cause difficulties during assembly and adverse effects during use. Additives, talcum and silicone oils are often used as a remedy.
Fluorination significantly reduces contamination by additives and avoids other disadvantages. Fluorinated surfaces retain their properties over long periods even when subject to regular cleaning and sterilisation. Reduced surface stickiness also reduces soiling, enhancing the components' visual appeal.

Process background

Intensive fluorination causes the fluorine atoms to be embedded in the surface. Stickiness and static and dynamic friction are significantly reduced. This effect is enhanced by the inherent increase in surface roughness while the rubber-specific properties remain unaffected.


  • To minimise friction and soiling
  • To reduce creaking and crackling caused by high static friction between rubber and mating surfaces
  • To reduce stick/slip effect in sliding motion
  • To facilitate assembly
  • To enhance visual appeal
  • To reduce stickiness: Release agents become obsolete, parts are easier to separate, and parts subject to static load release without effort.
