Basically, it is a gas that’s been electrified charged with freely moving electrons in both the negative and positive state.
How does plasma work?
We generate plasma by exposing gas to electrical energy. In doing so, the involved gas molecules are ionized, which means that electrons start to leave the gas molecules, creating a plasma which is highly electrically conductive and can interact with any surface. Surface treatment can now be initiated by placing any surface in contact with the plasma. We can fine tune the effects of this treatment by choosing the right gas mixture and process parameters for each product.

What is plasma cleaning?
Inert and oxygen plasmas are ideal for cleaning. The plasma cleaning process removes, via ablation, organic contaminates on the surface of most industrial materials. These surface contaminants undergo repetitive chain scission under the influence of ions, free radicals and electrons of the plasma until their molecular weight is sufficiently low to be reacted away in atmosphere. To obtain molecular cleanliness, there is not a more effective method than plasma.

What happens when a polymer is treated?
When a polymer or elastomer is treated in an inert gas or a non-carbon containing gas such as oxygen, ammonia or nitrous oxide, the primary result is the incorporation of different moieties of the process gas onto the surface of the material being treated. For example, the surface of polyethylene normally consists solely of carbon and hydrogen; however, in an appropriate plasma the surface may be "activated" to contain a variety of functional groups including but not limited to hydroxyl, carbonyl, peroxyl, carboxylic, amino and amines. Almost any polymer or elastomer surface may be modified providing chemical functionality to specific adhesives or coatings, thus significantly enhancing the adhesion characteristics and permanency.

What Causes Plasma Treatments to Decay?
Type of Material
- The characteristics of the material undergoing plasma treatment are one of the most important factors that affect the rate of hydrophobic recovery. Some polymers are more tightly packed, and the sub-surface molecules have less freedom of movement, hindering their ability to relocate to the surface and thus slowing down the recovery process. Conversely, lower density polymers ca…
Duration of Plasma Treatment
- There is some evidence that a longer exposure time to plasma may result in a higher number of surface and subsurface bonds of the material being broken by UV radiation from the plasma, leading to easier chain motion of molecules in the bulk of the material and hence a more rapid recovery process. Some research even states that plasma times of just 5 seconds are sufficient…
Storage Conditions
