Wearable Technology That's Comfortable and Easier to Convert

FLEXcon® dermaFLEX™ NNRU - Nylon Reinforced Polyurethane with Biocompatible Skin Contact Adhesive

Flexible electronics are moving into a new realm. They are enabling the development of medical monitoring devices that can be worn directly on the skin rather than being strapped on. 

Comfortable for Patients

The challenge? Finding a substrate that’s thin enough to be lightweight, flexible enough to move with the body without pulling, and permeable enough to allow the skin to breathe – all while staying adhered for the prescribed period of time without causing irritation.

  • dermaFLEX NNRU disappears on the body in both sight and feel.
  • It’s thin and flexible enough to conform to body contours and stretch with movement, but also return to its original dimensions rather than getting baggy.
  • The H-566 acrylic pressure-sensitive adhesive is non-cytotoxic, non-irritating and non-sensitizing, as defined by the ISO-10993 standard.
  • The high-tack adhesive provides excellent long-term adhesion to human skin.

Rigid Enough for Converting

The challenge for converters is that the films that meet comfort requirements are flimsy, making them very difficult to process because they tend to fold back on themselves like plastic wrap, even when coated with adhesive.

  • dermaFLEX NNRU is a .001” clear nylon reinforced polyurethane film.
  • It’s much easier to convert than your typical 1 mil PU film because the nylon reinforcement provides enhanced dimensional stability.
  • It’s compatible with EtO and gamma sterilization procedures.
  • The 50 lb. kraft release liner offers a good diecutting base.

Customizable

We can change the adhesive, adjust the adhesive coat weight, or swap out the liner to meet the unique specifications of your application.

More Than Medical

This technology isn’t being limited to medical. Wearable devices have the potential to replace personal tracking devices worn as bracelets or necklaces by allowing consumers to wear their devices directly on the skin and out of sight. dermaFLEX™ NNRU is rigid enough to convert easily and flexible enough to provide optimum comfort.

We found ourselves in need of a partner that could help advise us during the development phase of a new skin contact project. FLEXcon was the ideal partner; they offered the unique opportunity to work with a manufacturer who could put together a team of experts for us to collaborate with…to conceptualize a breakthrough solution.
