Teflon is a household name that commonly invokes images of eggs sizzling on a skillet, spatulas flipping pancakes, or rice steaming in a pan.
But, there is much more to this magical non-stick coating.
Teflon, a brand name for PTFE (polytetrafluoroethylene), prohibits food from sticking to pots and pans because of its hydrophobic properties.
As a low-energy, fluorocarbon solid neither water nor water containing substances can influence the surface. This means that nothing will stick to the surface or penetrate it.
Today, Teflon has improved culinary pursuits and made cooking more accessible, but that isn’t the only field PTFE has influenced.
The medical device industry would not be what it is today without PTFE. As medical devices work intimately with the human body, they must be completely sanitary, inert, and harmless.
With its lubriciousness and impenetrable properties, PTFE is used to coat a variety of medical devices such as catheters, surgical equipment, balloons, bladders, and implants.
But, PTFE only works when the coating itself sticks to the surface. This requires proper surface preparation which can be challenging in any manufacturing floor. It’s especially difficult in medical device manufacturing as specifications are so high and there is no room for failure. …Read More
Visit booth 220 or attend the presentation of Chief Scientist, Dr. Giles Dillingham.
What is known as The Plastics Technology Conference, ANTEC (Annual Technical Conference) 2017 brings together diverse members of the plastics industry from around the world. Taking place in Anaheim, California May 8-10, ANTEC 2017 showcases the latest technologies and advancements in the plastics industry.
Dr. Dillingham’s presentation, “Rapid Evaluation of Surface Properties of Medical Tubing for Process Development and Quality Assurance” explores methods of quality assurance testing on sensitive medical tubing. Significant properties of medical tubing–adhesion, wettability, antithrombogenicity, biocompatibility—allow for the ability to deliver fluids, gases, drain, and enter the body effectively. Yet, these properties depend on the top 2-3 molecular layers of the tube’s surface. This is why precise control of the surface is crucial for the success of medical tubing. But, this can be challenging. Laboratory techniques such a FTIR and XPS can reveal surface composition, however, these methods are not practical on the manufacturing floor.
AMI Medical Tubing 2016
BTG Labs will host a booth and present at the Applied Marked Information (AMI) Medical Tubing Conference September 13-14, 2016. The event will take place in Crowne Plaza Boston-Woburn, Woburn, Massachusetts. This international event displays the latest in polymeric medical tubing and catheters, covering designs, materials, production and applications. The conference will host discussions on the latest standards and certification requirements. This field of medical device manufacturing is growing and evolving rapidly along with the use of polymers in medical tubing.
BTG Labs and the Surface Properties of Medical Tubing
BTG Labs will present on the sensitive and complex surface properties of medical tubing such as wettability, adhesion, antithrombogenicity, and biocompatibility. These properties depend on the chemical composition and structure of the uppermost 2-3 nanometers of the material. Thus, monitoring and managing these properties is crucial in manufacturing. This can be challenging as surface monitoring devices such as total reflectance infrared spectroscopy (ATR-FTIR) and X-ray photoelectron spectroscopy (XPS) can be impractical to employ on the manufacturing floor. BTG Labs will discuss the Surface Analyst™ and ways in which it can be utilized to monitor these minute surfaces accurately and sensitively on the factory floor. …Read More
