Plasma and Corona Treatment in the Medical Device Industry
Discover how plasma and corona secure stronger, more consistent adhesion for critical medical components.
Low surface energy in plastic materials challenges you in bonding, coating and printing processes. Durability and quality are important factors in
manufacturing medical devices and an efficient surface treatment is required to optimize these processes.
Plasma and Corona Treatment modifies the chemical structure in the surface of plastic materials and improves surface tension.
The result is uniform treatment and improved adhesion and wettability properties with long durability and the possibility to achieve high quality results in bonding, coating and printing.
Suitable Surface Treatment Solutions for the Medical Device Industry
With plasma and corona treatment, you have the ability to achieve:
- Even and uniform treatment to all surfaces on Three Dimensional parts
- Treatment of specific hard to reach spots on Three Dimensional parts
- Surface modification without affecting the bulk material
- Cost efficiency and long lasting durability of adhesion properties
- Environmentally friendly solutions
Plasma and corona surface treatment is applied for surface activation of:
- Needle Hubs
- Syringes
- Catheter Tubing
- Ostomy Bags
- Petri Dishes
- Culture tissue
- Lenses
How does plasma cleaning sterilize surfaces in biomaterials research?
Plasma cleaning sterilizes surfaces in biomaterials research by removing microbial contaminants. The process involves the use of plasma, which consists
of ionized gas with ions, electrons, and neutral atoms. This ionized gas creates reactive species that can effectively eliminate organic contaminants,
including microbes, from surfaces. This makes plasma cleaning extremely beneficial for sterilization purposes in biomaterials research applications.
Corona Treatment of Medical Devices
As corona treatment is a bonding treatment, it is commonly used nowadays to treat medical equipment and make its surface adhesive for printing ink.
Examples of the medical products subjected to this treatment include; the barrels of plastic syringes, medicine bottles, transparent tubes used for fluids,
and even surgical scrubs.
When the air around the surface of a product is exposed to a high voltage charge, it creates a frenzy of atomic energy. The oxygen molecules start
breaking and merging with others present in the product material, resulting in a surface that is more prone to adhesion.
Texturally, a corona treatment of medical devices changes the surface from a smooth and slippery one, to a rough and coarse texture that will grab
the ink, adhesive or coating more rapidly. The change in the chemical make-up of the surface allows things to adhere to it which is a stronger bond
than simple mechanical bonds.
Benefits of Corona Treatment of Medical Devices
There a number of benefits of using corona treatment for medical devices. A few of these are:
- The corona treatment improves the flexibility of plastic and laminated materials and allows the manufacturer to mark their products with a seal,
logo or label of their choosing. - It also provides an element of safety, as previously, an open flame was used to create this chemical reaction manually.
- Corona treatment of medical devices is extremely effective, especially in the case of three-dimensional parts, because the machine has a number
of heads that can treat the object from various angles, allowing for complete coverage at a single time. - If manual labor was hired to sand the smooth surfaces, it would be very costly for the manufacturing companies; hence, corona treatment of
medical devices is also cheaper and cost-effective as compared to the manual methods. - Although corona treatment of medical devices is commonly being performed, this treatment is also being used in a wide variety of industries, such
as automobiles, electronics, pipes, ophthalmic lenses, electrical cables and wiring, etc.
Hence, the use of corona treatment to alter the surface composition of objects and to create strong adhesive bonds is a big success and its numerous
benefits make it the ultimate choice for product manufacturers from a range of industries.
