From biocompatibility to stress distribution, adhesion has proven to be extremely important in medical devices that are TPU-based.
Applications of TPU in Medical Devices
Thermoplastic polyurethane is common with numerous medical devices. Some medical devices using TPU are catheters, wound dressings, pressure-relieving pads, air sacs, hospital bed mattresses, protective membranes, isolation tents, dental materials, compression stockings, wearables, and flexible tubing.
TPU is a plastic with high-performance abilities that offers several medical advantages. TPU is rigid, flexible, and adaptable. It has resistant and durable properties that can enable it to last the test of time.
Adhesion Challenges
TPU lacks the required surface energy to bond effectively with other items. It’s also prone to contaminants, which can affect the adhesion quality.
TPU molecules are arranged so that they cannot create strong bonds with adhesives or coating.
Therefore, before TPU is used for coating and adhesion applications, its surface energy has to be increased..
Understanding Oxygen Plasma Cleaning TPU
By delving into the mechanics of oxygen plasma cleaning TPU, we can unlock its potential for optimizing adhesion and surface properties in diverse applications.
What is Oxygen Plasma Cleaning?
Oxygen plasma cleaning is about using plasma to clean material surfaces. The concept behind oxygen plasma cleaning revolves around using ionized gas (oxygen) to eliminate organic and inorganic impurities while altering surface chemistry.
Plasma combines with the material surface to modify its surface characteristics. Plasma is the chief component in the process and is produced from the ionization of gas particles.
Mechanism of Surface Activation
TPU owes its insufficient surface energy nature to its molecular arrangement. The arrangement of TPU molecules is responsible for its low wetness potential and low affinity for different materials.
When TPU goes through oxygen plasma cleaning, special chemical groups are deposited on the surface to increase its polarity and make it more receptive to other materials.
The newly formed polar groups increase the surface energy of TPU and rearrange its molecules to enable it to form strong bonds with coating and adhesives. This is a significant milestone in medical devices.
Unique Effects on TPU
