Plasma technology
Plasma technology has established itself as a versatile tool in surface activation and treatment processes, thanks to its ability to modify materials without direct contact, without aggressive chemicals and with unmatched precision.
At INFINITIA, we apply this technology in demanding industrial environments, offering customized solutions for cleaning, disinfection, improved adhesion or surface functionalization. In our laboratory, we have specialized equipment for atmospheric plasma and DBD (Dielectric Barrier Discharge), which allow us to treat plastics, metals, ceramics, and other materials with maximum efficiency.
Thanks to our team of engineers and technicians, we develop plasma-based solutions that integrate seamlessly into production chains, providing added value from a functional, economic, and environmental standpoint.
What is plasma technology?
Plasma technology involves the use of an ionized gas—known as the fourth state of matter—to modify the surface of materials at the molecular level. Through the use of cold plasma or atmospheric plasma, reactive species are generated that interact with the outermost layers of the material’s surface, altering its physical or chemical properties without affecting its internal structure.
Depending on the application, plasma can be used to remove contaminants, activate chemical bonds, increase surface energy or introduce new functional groups. At INFINITIA, we adapt each type of treatment to the nature of the material, the customer’s requirements and the service conditions, allowing the data generated to be used in R&D, process improvement or product validation.

Benefits of plasma technology
One of the main benefits of plasma treatment is its ability to improve adhesion in assembly, coating, or painting processes, which translates into greater reliability and durability of the final product. For example, in sectors such as automotive or medical devices, plasma surface activation allows for a more effective bond between plastic and metal components, without the need for chemical primers.
In addition, its use in surface cleaning processes allows the elimination of volatile organic compounds (VOCs) without generating waste, which is key in environments that require high standards of hygiene. At INFINITIA, we apply this technology to optimize processes, prevent failures, and improve product quality, aligning ourselves with the demands of modern industry.
Plasma technology at INFINITIA
At INFINITIA, we develop customized plasma treatments for each client, from the prototyping phase to industrial validation. Our laboratory is equipped with advanced technology to generate plasma adapted to multiple configurations: continuous, batch, or experimental. We work with total control over parameters such as pressure, temperature, gas composition, and power, which allows us to ensure stable, reproducible, and scalable treatments.
In addition, we integrate the use of plasma into innovation projects, thus expanding the possibilities of application in sectors such as electronics, packaging, automotive, health and renewable energies.

Types of Treatments with Plasma Technology
At INFINITIA, we apply different plasma technology treatments to modify the surface properties of materials, improve their functional performance, increase adhesion, or facilitate subsequent processes such as painting, bonding, or coating. We adapt the type of atmospheric plasma or DBD used according to the industrial application, the type of substrate, and the customer’s technical requirements.
Plasma treatment for surface activation
This treatment increases the surface energy of the material, promoting the adhesion of paints, coatings, or adhesives. It is especially used on low surface energy polymers such as polypropylene or PTFE.
At INFINITIA, we use this type of plasma activation on automotive plastic components, achieving better adhesion of primers without the need for prior chemical treatments.
Plasma treatment for cleaning and disinfection
Through exposure to cold plasma, it is possible to remove organic contaminants, particles, and microorganisms in a non-invasive way. This technique is applied to surfaces that require high-precision cleaning without damaging the substrate.
An example is its use in industrial components, where at INFINITIA we have applied atmospheric plasma for cleaning metal and plastic components.
This process allows functional groups to be incorporated into the surface of the material (hydroxyls, carboxyls, amines, etc.), which modifies its behavior in relation to moisture, adhesion, or interaction with other compounds.
In a packaging project, at INFINITIA we applied plasma to improve the properties of the material without adding additional layers to the film, thus optimizing the sustainability of the product.
Removal of volatile organic compounds (VOCs) and air treatment
Plasma allows the ionization of air and the removal of volatile organic compounds (VOCs) without generating toxic by-products. It is used in air purification systems or industrial gas treatments.
At INFINITIA, we advise on the integration of this technology into purification systems to reduce emissions in environments with volatile substances.
Plasma treatments in R&D systems
Thanks to its versatility, plasma is also used in research and development environments, both in academic laboratories and in high-tech industries.
At INFINITIA, we collaborate with research centers and innovation departments to study new surface treatments for semiconductors, composite materials, and technical textiles.
Industrial Applications of Plasma Technology
The plasma treatments developed by INFINITIA have direct applications in numerous industrial sectors. Their ability to modify the surface of materials without altering their volume, their compatibility with production lines, and their clean, residue-free nature make this technology particularly valuable in highly regulated or technologically advanced sectors. In addition, it improves material performance, reduces production costs, and replaces more polluting traditional processes.
Automotive Industry: Improved adhesion and durability of components
The automotive industry requires materials capable of withstanding vibrations, humidity, thermal variations, and extreme conditions of use. In this context, plasma treatments ensure proper bonding between materials and prepare surfaces for paints or functional coatings.
