Surface treatment with low-pressure plasma
Plasma is the term used for an excited (ionised) gas. In that state, the atoms/molecules are in a highly excited state. The technologies used by pfm medical permit the use of plasma at low thermal loads. Plasma processes are ideally suited to activating temperature-sensitive surfaces.
One effect of surface activation by low-pressure plasma is greatly improving the bonding properties of the carrier material and thus ensuring the extremely strong adhesion of, for example, pigment particles to the surface without any changes to the material properties of the activated product.
Unique – the titanisation of mesh implants
A prime example for the application of this plasma technology (low-pressure plasma) is the refinement of surgical implants with covalently – thus practically inseparably – bonded titanium oxide. In a globally unique process, a thin (less than 100 nm; 1 nanometre = 1 millionth of a millimetre), highly biocompatible titanium oxide surface is applied to a polypropylene mesh.
