Plasma coatings for medical plastics


Injection molded plastic parts are key components of medical devices, molecular diagnostics, microplates, catheters, surgical instruments, and other emerging technologies in medicine and cell biology. When selecting a particular plastic for an application, the design engineer has to take into account many constraints, including resin properties, shrinkage, part complexity, wall thickness, mechanical strength, impact strength, thermal stability, opacity, surface finish, color, etc. Once the resin has been selected, and the molded plastic parts made, another set of design issues arises:

A) How do I glue my parts together and obtain sufficient adhesion?

B) How do I achieve proper fluid flow through small channels without trapping bubbles?

C) How do I promote cell growth on some surfaces, but not on others?

D) How do I make surfaces that remain hydrophilic throughout the product’s shelf life?

E) How do I control wetting on diagnostic surfaces?

These issues all deal with the properties of the plastic surface. When you add the surface requirements onto the bulk material constraints the design objectives can seem overwhelming.

Surfx offers a way for you to tailor the plastic surface to the desired properties independent of the resin selected for the injection molded part. We deposit coatings, 10 to 100 nm thick, onto the surfaces where you need to control adhesion, wetting, cell growth, etc. These strongly adherent, transparent, biocompatible coatings give your product the precise properties it needs at an economical cost. Our atmospheric plasma tools lay down these coatings on the surface of any 3-D plastic part, regardless of the resin type (e.g., ABS, acrylic, liquid crystal polymer, nylon, polycarbonate, polyester, polyethylene, HDPE, polypropylene, polystyrene, and polyurethane). Please contact our engineers so we can help you solve your toughest surface challenges.

Visit Surfx at MD&M West 2017


MDM West

Surfx Technologies will be exhibiting at the upcoming MD&M West show in Anaheim February 7th, 8th, and 9th. MD&M West is the world’s largest medical device technology exhibition and we are excited to demonstrate our world-class plasma systems at the show. Stop by and see us at booth 254 to learn more about how in-line atmospheric plasma treatment can improve your processes. A Surfx Atomflo 500 plasma system will be operating in the booth, offering you a hands-on experience with the system. If you have some parts that you’re interested in getting treated, feel free to bring them by and we’ll activate them in the booth in a matter of seconds. Our Atomflo 500 plasma system features water-cooled sources and a variety of gas chemistry options, enabling a wide range of surface modifications on thermally sensitive devices. It is highly suited to performing repeatable, non-damaging treatment of fine tubing, membranes, and microfluidic devices.

Show hours are 9:30AM to 5:00PM February 7th and 8th, and 9:30AM to 4:00PM February 9th. The show is held in sunny Anaheim, CA at the Anaheim Convention Center. You can learn about the latest atmospheric plasma developments and visit Disneyland all in one day. We look forward to seeing you at the show!

Air plasmas versus Surfx’s atmospheric pressure argon plasma – Do you want cheap gas, or high yield?


Air plasmas boast low operating costs because they use compressed air. However, to operate this way, they must employ a blown arc, or dielectric barrier discharge (DBD). In both cases, non-uniform sparks shoot out of the discharge nozzle, which may result in non-uniform treatment of your parts. These plasmas operate with high voltage power supplies, up to 24,000 V. The high voltage is required to breakdown the air. Consequently, the plasma sources must be operated with robots away from personnel to eliminate the risk of electric shock. The blown arcs yield faster treatment speeds then DBDs due to the high degree of gas ionization in the arc. Yet this means the gas is much hotter, and can thermally damage or even melt the part.

Surfx offers atmospheric pressure argon plasmas that are driven with low-voltage, radio frequency power supplies. There is no risk of electric shock. The plasma beam is uniform, and provides the fastest and highest level of surface activation achievable. Surfx’s plasmas are cold so that there is no risk of thermal damage to the most sensitive polymers, such as high-density polyethylene (HDPE) and polypropylene (PP). Furthermore, unlike blown arcs, the plasma sources operate for long periods of time without needing to replace expensive electrodes.

Now I know our competitors are going to tell you that the argon is really expensive and not worth the trouble. This is simply not true. One of our minibeam plasma sources suitable for treating the same parts as open-air plasmas runs on 10 liters per minute of argon. Assuming one runs the Surfx argon plasma 24 hours per day, 350 days per year, the annual cost will be $8,365 USD (for bulk liquid argon purchased in the United States). In China where bulk argon is a lot cheaper, the annual cost will be $3,024 USD.

Using the Surfx argon plasma, a typical part made of molded plastic, glass or metal can be activated for adhesion in 5 to 20 seconds. At 10 seconds per part, one machine can treat about 3 million parts per year. In this case, the gas cost per part is 0.0028 USD in the USA and 0.001 USD in China.

You have got to ask yourself what is more important, having 100% product yield, or saving a few tenths of a cent per part?
