We strive daily to come up with innovative answers to the problems our clients face. In order to support atmospheric plasma processes (Open air-Plasma®) and low-pressure plasma technologies, Plasma Treat provides a wide range of plasma systems and equipment (Aurora).

During this time, plasma technology has also shown to be quite useful in a variety of other industrial sectors, including the automobile, medical device, textile, and aerospace industries, to mention a few. What is plasma therapy and what can it accomplish?

A variety of businesses, including pharmaceuticals, food, and more, have adopted the approach, but in what context? We've compiled several instances of plasma surface treatment usage in industrial applications to help you better comprehend the use of plasma surface treatment and its adaptability.

Aerospace, automotive, contact lenses & optics, filter media, medical plastics, microscopy, PCB / electronics, assembly, plastic cards & loyalty cards, print adhesion, plasma systems for, R&D/academic, textiles & fabric are among the industries where plasma can be employed.

Today, plasma technology is widespread throughout practically all industrial areas, and new uses are continually being created. This cutting-edge technique enables the customization of many different types of surfaces. As a result, several applications are possible.

Before any glueing, printing, or lacquering can occur, applying plasma treatment to such plastic surfaces can produce an efficient pretreatment of surface activation. Similar to this, plasma may also be used to treat materials like glass and ceramics.

Polypropylene, the main component of plastics, is homopolar, which implies that bonding is difficult. Before any glueing, printing, or lacquering can occur, applying plasma treatment to such surfaces can produce an efficient pretreatment of surface activation. Similar to this, plasma may also be used to treat materials like glass and ceramics.

To aid ink, adhesive, coating, sealant, and paint adherence, plasma Treaters provide plasma surface treatments. Additionally, it might clean the surface in the most perfect ways. In-line plasma treatment equipment is integrated by the producers or factories to improve adhesion on surfaces made of plastic, composite, metal, and glass. By improving wettability and surface energy, the plasma pretreatment process cleans, etches, and functionalizes surfaces to activate bonding regions. With this plasma surface treatment, it may be simpler to print, paint, apply adhesive, clean, weld, etc. on the surface of the items.

The use of plasma for plastic packaging is quite successful: The best plastic activation is possible with Openair-Plasma® surface modification technologies. Extremely long-lasting plasma activation prolongs the period of storage and makes processing easier up to 12 months afterwards.

Plasma treatment of plastics involves both surface activation and cleaning in order to increase adhesion. First, the plasma treatment removes volatile organic components from the plastic that would otherwise prevent bonding, painting, and glueing.

Plastic and composite materials can be cleaned, prepared, and made ready for finishing using plasma treatment. The improvement in adhesion caused by plasma treatment's increased surface energy ensures the efficiency of a coating that has been applied.

If we assume that the process modifies a material's qualities, it is crucial to comprehend how and why this can be required or desirable.

By applying a plasma treatment to polymer surfaces, surfaces can be altered in a variety of ways (etching, cleaning, activation, cross-linking), which can improve wetting qualities, increase the adherence of plasma-deposited coatings, or decrease friction.

Plastics are Treaterd with plasma Plasma treatment of plastics involves both surface activation and cleaning in order to increase adhesion. First, the plasma treatment removes volatile organic components from the plastic that would otherwise prevent bonding, painting, and glueing.

A low-energy surface is transformed by plasma treatment into a high-energy surface that is more hydrophilic and wettable. The more wettable a surface is, the greater the adherence of a coating; the opposite is also true.

An example of electrical surface treatment is plasma surface treatment. It alters the chemical characteristics of material placed inside an energy stream using the force of electrical energy. Electrically charged molecules interact with a material more vigorously, improving wettability and strengthening bonding characteristics.

Utilizing an electric field and reactive gas molecules, plasma surface treatment is produced. This technique forces a highly ionised field onto the desired surface by using one or more high voltage electrodes to charge the molecules of the surrounding blown gas.

In atmospheric plasma, a strong jet of heated compressed air is directed at the surface of a component. It's an excellent technique for producing a focused, high-performance surface. Atmospheric Plasma Surface Treatments are a good option if you want to clean or activate a material's surface and are best used in inline processing.

In order to increase adhesion, organic and inorganic impurities that are present on the surface are removed using a plasma surface treatment. A cost-effective method for cleaning and activating complex surfaces is plasma surface treatment. Prior to printing and bonding, it is utilised. Complex surfaces that cannot be handled with standard treatments like corona mechanisms typically require this treatment. Metal, plastic, and carton surfaces with plasma surface treatment have increased adhesion. Low temperature is used in the plasma surface treatment technique. The surface undergoes a number of chemical and physical changes throughout this process, and specific thick and cross-linked layers are created, increasing the surface's adhesiveness. The wettability and adhesion of ink, glues, and coatings on various surfaces are improved through plasma surface treatment.

If the Treaterd area is clean and dry, most plasma treatments endure for 48 hours. Depending on the procedure used and the environment in which the components are stored, this period may change.

Any surface may easily be primed for improved reception of secondary industrial applications through the use of the surface modification technology known as plasma treatment. As long as there is an electric potential difference, positive and negative ions, electrons, and radicals will react and collide in the reactive treatment process known as plasma.

When corona therapy, which once again ionises simply air, is unable to deliver the necessary therapeutic outcomes, plasma systems are utilised. In certain circumstances, plasma treatment results in greater and more durable surface effects than corona, but the advantages must outweigh the expenses of extra equipment and maintenance.

Plasma can be used to make glass more hydrophilic, raise its surface energy, and enhance its wettability, allowing inks, paints, or adhesives to adhere more effectively. Additionally, it may eliminate pollutants on surfaces that are organic, inorganic, or microbiological and develop as a result of contact to air.

Many materials may have their surface energy increased using a method called plasma surface treatment, which enhances the bonding properties. The corona treatment, a type of plasma therapy developed by the Danish engineer Verner Eisby in the 1950s, is another name for this procedure.

In order to boost surface energy, surface polymer functional groups are changed to other atoms from ions during plasma surface activation. A surface is frequently prepared for bonding or printing via plasma activation.

A surface can be altered by plasma bonding so that it can be bonded to or printed on. This procedure, which is frequently employed on Teflon, rubber, or plastics, actually alters the surface, leaving behind free radicals and enabling any substance to dependably connect with glue or ink.

Polydimethylsiloxane, sometimes known as PDMS, is a silicone-type polymer that is widely utilised for a variety of uses. The repeating Si-O group-containing siloxane unit is what gives silicones their distinctive properties. The silicon atom can be bonded to a broad variety of side groups. They are methyl groups CH3 in PDMS. Can be connected to the polymer in a variety of ways via different chain ends. Frequently, this is the Si-SH3 trimethylsiloxyl group. Hexamethyl disiloxane HMDSO is the shortest dimethysiloxane monomer-free dimethysiloxane molecule and is crucial as a process gas for hydrophobic plasma coating. Up to very high molecular weights, PDMS linear polymers are liquid. They can, however, be crosslinked to provide elastomeric characteristics. PDMS is a nearly inert polymer that has a great resistance to oxidation, but it may also be utilised as an electric insulator in biological micro-analytics and organic electronics (micro-electronics or polymer electronics). In the area of micro-fluidic systems, low-pressure plasma with PDMS is frequently used; in this case, the client structures a specific polydimethysiloxane (such Sylgard 184) to suit the particular application. The PDMS chip can then be permanently connected to a glass plate, a silicon surface, or another substrate after undergoing a plasma treatment.

Benefits of pre-treating micro-fluidic systems with plasma:

Rapid processing.
Connections between the PDMS and the substrate surface that are irreversible lead to the creation of impermeable channels in the micro-fluidic component.
