Growth of Medical Wearable Devices Increases
Specialized release liners

Vast drivers for wearable medical devices

The healthcare and medical industries have seen significant changes in the past ten years, and continued investment in new products is expected in the coming years.  The use of technology applied to all wearable devices (fitness and health gadgets, reality gaming devices, and smart watches, for example), including medical wearable devices such as transdermal drug delivery systems, and patient monitoring systems will remain strong.  Medical wearable devices involve skin contact and medical grade adhesives.  Developments in these areas necessitate the highest quality raw materials, including release liners.

There are many technological and societal changes that are driving the use of wearable medical devices.  Everyone in the value chain, from raw material suppliers to consumers is experiencing transformations in the way that products are designed and used.  Some of the most significant drivers for wearable medical devices include:

  • Advances in wireless technology such as Bluetooth Low Energy (BLE), which supports long-term use and increased connectivity
  • Consumers’ fascination with self-monitoring is carrying over into the clinical arena
  • A rise in chronic conditions, from diabetes to heart disease to COPD, whose management depends on ongoing monitoring
  • Efforts to cut healthcare costs by shifting care to outpatient settings, including the home, while maintaining clinical oversight of the patient

Silicone Adhesives offer advantages for performance and patient comfort

Silicone adhesives are a preferred material for medical applications because they deliver the appropriate adhesion with gentle removal.  Throughout the device’s application, therapeutic wear and removal, the adhesive must ensure that the device stays in place and does no damage to the skin.  Because silicone adhesives deliver the right balance, their use in the medical market has expanded exponentially in the last decade.   

Medical adhesive suppliers have continued to develop pressure-sensitive adhesives that meet the needs for a wide variety of medical devices and a wide variety of skin types.  These developments have resulted in the growing use of silicone adhesives in geriatric, neonatal and other fragile skin care applications to enhance patient comfort, extend wear time, and minimize the risk of damage upon removal.

Ensuring Release Liner Compatibility

When using a silicone adhesive it is imperative to choose the right release liner.  Traditional solvent and solventless platinum catalyzed or solvent tin catalyzed silicone coatings, for example, will not properly release from these silicone adhesives.  Additionally, high temperatures are needed to cure these adhesives, and special release liner substrates are required for these processing conditions. 

Fluoro release systems coated on polyester film release liner substrates are the most commonly offered and most compatible release systems available today for use with silicone adhesives.  Additionally, new non-coated release films are being introduced and should be considered for applicability.
