Company Profile

COLD PLASMA SURFACE TREATMENT

PVA TePla Plasma Systems leads in the area of Life Sciences through its leading edge development and applications of advanced technologies by our scientist working in cooperation with our broad customer base and a global network of research institutes and universities.

Our products and applications are utilized across a very broad spectrum including biotechnology, pharmaceuticals, biomedical technologies, life systems technologies, food processing, environmental, biomedical devices.

In the medical, electronics, semiconductor and industrial markets, material surfaces that require cleaning, coating or chemical modification are immersed into the energetic low-pressure environment with an RF plasma. In addition to the strong chemical effects of an RF or Mw plasma, directional effects also play an important role. Particles carrying momentum to the surface can physically remove the more inert surface contaminants, and cross-link polymers to lock the plasma treatment in place.

PVA TePla's line of atmospheric plasma products has also found their niche in the same broad spectrum of industries as low-pressure systems. The low capital cost, localized treatment and in situ application of atmospheric plasma have opened new markets for surface modification by plasma.

Choice of material in today's manufacturing arena is paramount. Certain polymers, for example, offer ideal structural characteristics being light weight, strong, moldable, and above all low cost. However, the criteria defining such bulk characteristics often conflicts with required surface properties. Adhesive bonding, potting, encapsulation and ink marking are difficult with most polymers. Elastomers, used for seals and o-rings, inherently have high coefficients of friction. Immuno-assay and cell culture plates have limited bio-response. Instead of finding new materials that meet the right compromise between bulk and surface, gas plasma treatment utilizing PVA TePla's 40 years of process development experience allows for custom tailoring of the surface characteristics to meet application needs without changing the bulk properties of the polymer. This means that you can continue using your material of choice and plasma processing will ensure that your product can be adhesively assembled, printed on, have reduced surface friction, increased surface functionality, etc.

If you are looking for a solution to a unique materials problem or are considering low pressure or atmospheric plasma for etching, cleaning, decontaminating, bonding, printing, functionalizing, sterilizing; or trying to apply a unique coating using PECVD or sublimation then PVA Tepla is a perfect company to help you fast track your product to the market. Together with our business partners we are able to offer a complete range of products and also provide superior technical competence in our labs where we can recommend, demonstrate and test material specific surface treatments, adhesives, potting compounds, UV or IR Curing stations, metrology equipment, and unique coatings across a broad spectrum of devices and markets.
