Plasma cleaning & plasma surface modification
You are here -- About plasma - Plasma applications
Applications for plasma processes. Common examples.
Plasma cleaning, Surface activation preparation for painting and bonding
- Material cleaning for medical applications
- Removal of release agents in the plastics industry
- Bonding and soldering preparation in the electronics industry
- Organic rest contamination such as wax, release agents, oil rest from production processes can all be
completely removed with low pressure plasma cleaning.
- Also hollow items can be cleaned in a special plasma cleaning process.
Activation of plastics
Preparation for painting
Preparation for bonding
Increasing the surface energy
During plasma activation the surfaces are chemically changed.
Functional groups (e.g. OH-groups) are deposited, these then act as anchoring for the paint or adhesives.
Plasma etching of plastic surfaces
The plasma etching of polymer surfaces results from a longer processing period.
- Plasma etching of PTFE, POM, PA, PEEK prior to painting or bonding
- Lasting hydrophilic surfaces
- Shine removal from surfaces
During this process minute amounts of material from the polymer surfaces are removed.
This removal results in microscopic pits in the surface of the polymer providing the paint or adhesive with a greatly increased surface area to anchor to.
Especially with high performance polymers such as PTFE, POM, PA, PEEK it is necessary to perform a plasma etching process as preparation for painting or bonding.
