Bonding with plasma

Osnabrück University about the physicochemical characterization and bonding of plasma-modified polyetheretherketone for dental applications

In the beta test phase Oliver Beier and Andreas Pfuch of INNOVENT e.V. Technologieentwicklung in Jena have investigated the plasma activation of various plastics after treatment with the piezobrush® PZ3 and the module “Standard”.

The piezobrush® PZ2 is used at Rimkus Medizintechnik to guarantee secure adhesive joints between silicone and plastic.

Bonding of polypropylene (PP) in medical technology production is often of insufficient quality, therefore plasma is used for quality assurance at IKA Group.

With low-energy surfaces such as silicone, polypropylene or Teflon, a strong increase in surface energy is achieved after surface activation with the piezobrush PZ2 handheld plasma device.

The Max Planck Institute for Astronomy uses the piezobrush PZ2 for plasma activation of CFRP and glass/glass ceramic adhesive surfaces.

Sabine Schmidt from ISAT at Coburg University reports on the use of plasma in microfluidics to achieve a connection between PDMS and glass substrate.

Relyon plasma shows at Bondexpo atmospheric pressure plasma systems for optimised adhesive bonding

Atmospheric pressure plasma can be used in a variety of ways to achieve good adhesion and improve bondings. This makes the process an attractive alternative to chemical bonding agents and solvents.

Professional adhesive joints are also possible without large investments by using the piezobrush PZ2. ACT in the field report.

Plastics are usually characterized by inert surfaces with surface energies between 20 and 40 mN/m. In order to wet a surface, however, the surface energy of the polymer must exceed the one of the paint or the adhesive. This condition can be achieved through a plasma treatment of the surface and is called “activation“ in plasma technology.

The Plasmadust technology of relyon plasma enables the gentle deposition of powdery plastics on the metal.
