Atmospheric Plasma Treating Effects

Since its invention, atmospheric plasma treatment has continually remained in use for improving the surface energy levels of various materials. The process involves treatment of surfaces on a level of pressure that’s equal to the surrounding pressure i.e. normal pressure. Generally, atmospheric plasma treatment is used for pretreatment on a local level on different surfaces e.g. metal, polymers, glass, ceramics, and hybrid materials etc.

Among the most evident reasons for atmospheric plasma treatment’s popularity, efficiency is a prominent factor. The difference between Corona and Plasma is that the Corona treatment takes place at normal air pressure i.e. without the use of compressed air (as Atmospheric plasma) or by the use of vacuum. Adhesive customers are continuously looking forward for an increase in bond reliability without being subjected to process difficulties . Surface preparation that involves vacuum plasma is a bit more difficult as it involves the transportation of items from in and out of a vacuum chamber.

You could always reduce your costs by switching to a substrate that’s less expensive, of a cheaper material or supplier, or just reduce the amount of adhesive being used in the process. Do keep in mind that applying these changes would result in low reliability and weak performance of your products. On the other hand, by using atmospheric plasma treatment systems, you could easily cut down the costs and enhance bond reliability within micro seconds.

Based on the amount of strength that is required for a particular application, atmospheric plasma technology can provide customers with an option of seeking substrates that are less expensive or use lesser amounts of adhesive needed to attain particular bond strength. Though, the less expensive substrates are usually tricky to bond. The beam of plasma can be installed into the automated production lines on hand with nominal costs.

Atmospheric plasma treatment is used for a multitude of reasons such as treatment of parts prior to the bonding process, surface activation, and fine cleaning etc. The treatment presents a technique that is friendly for the environment and dry. Atmospheric plasma is also high quality plasma that could efficiently reduce operational costs and used locally.

One of the many advantages of air plasma treatment is its ability to treat difficult surfaces on higher levels. Plasma treatment is a feasible substitute for treating a variety of substrates that do not respond to the corona treatment process. For example, the corona treatment is in effective on materials made from fluoropolymers like Teflon® etc.

Plasma treatments are also beneficial for increasing life treatments to a considerable point. Substrates subjected to this treatment tend to retain their treated forms much longer than surfaces that have been exposed to corona. A lasting treatment will ensure an increase in inventory life along with providing the manufacturing sector with the much needed flexibility. This can also enable converters to gain advantage over scale economies during production.

Atmospheric plasma treatment is ideal for handling thicker substances. Usually, substrates which are thicker than the average diameter of .125” are unable to respond positively to the process of corona. These may include foams, metals, films, powders, fibers, non-woven and many other materials. And these surfaces can be actively treated by plasma.
