Pretreatment of Plastic parts by Plasma Activation

For activation processes, the Plasma typically consists of Oxygen, but sometimes Nitrogen or Ammonia. When Oxygen is used, it is possible to modify Polymers in such a way that Hydroxyl, Carboxyl or peroxide groups are formed on the Surface. On the other hand, if Nitrogen or Ammonia is used, this leads to Amine or Imine Groups, which can also be of interest for certain Applications. These polar hydrophilic Groups improve Surface wettability. Activation processes usually only last a few seconds. After activation, the Workpieces are prepared for immediate further processing, which may even be possible in the same Plasma System. A typical Area of ​​Application for this established process is the pre-treatment of plastic parts in Automobile construction, such as painted bumpers.
