Plasma Surface Activation is the process of treating the polymer to increase its ability to be dyed or printed on. Plasma Surface Activation is when weak bonds are replaced by reactive carbonyl, carboxyl and hydroxyl groups, the surface becomes super active and activation occurs thanks to functional groups such as amino group. Many polymers, especially polyolefins such as polyethylene and polypropylene, are chemically inert. These polymers cannot be easily bonded to other materials and show poor adhesion with inks, paints and adhesives. This is due to the absence of polar and reactive functional groups in their structure.
Plasma Surface Activation exposes many polymers to binders and coatings. Although Oxygen is generally used as the process gas, it can also be carried out with atmospheric air.
The gas to be used in the Plasma Surface Activation process is ionized by applying voltage and plasma is formed. Gases such as air, nitrogen, argon and helium can be used for plasma formation, depending on the place and purpose of use. Free radicals in plasma form a highly active surface against binding agents.
Advantages of Plasma Surface Activation
During the applied plasma activation, there is no change in the mechanical, chemical and bulk properties of the material.
No harmful gas emissions occur.
Easy to apply.
It is economical.
