What Silicon Material Stick Well On Human Skin

Kris Godbey, Senior Technical Back up Engineer for 3M Medical Specialties, recently spoke almost material pick and advanced assembly for body-worn devices. In a presentation, Godbey described by stick to peel is challenging, and what were some factors that could make device adhesion difficult. We present some excerpts:

Customers accept basic goals and expectation of silicone adhesives that it can agree the device or dressing in place while the device performs the intended part, until the time the clinical objective in achieved. The requirements are that:

In that location is good initial and long term adhesion;
The agglutinative is like shooting fish in a barrel to use and employ; and importantly,
It's easy to remove with minimal skin trauma.

Human peel is a notoriously difficult surface for anything to stick because of its low surface energy. Other factors affecting good skin adhesion include:

Dwell time or the length of time that the agglutinative is practical to the skin- longer the adhesive, lower the adhesion;
Cleanliness of the skin, which is affected by expressionless skin cells, surface oils and moisture; and
Roughness of the surface, which is affected by pilus and pilus regrowth and age factors – for instance, older pare is thin and frail and more exposed to conditions and lord's day and often dehydrated.
A typical person also generates an entire new skin surface in two to 5 weeks.

Traditional stick-to-skin adhesives can result in hair pulling at removal, and skin stretches resulting in mechanical trauma and possible skin stripping. Thus, medical adhesive tapes must balance betwixt acceptable adhesion levels for majority of users (in the centre of bell bend) and those at the ends of the bell curve. For instance, if the adhesion is too low, they will not stick well for the time needed; if the adhesion is too loftier, it could cause skin trauma, especially in people with delicate skin.

What are risk factors for pare stripping? This is mutual is very old or very young patients (geriatric or pediatric patients); those with fragile or sensitive peel; those with long-term corticosteroid utilize; and those who have had skin changes because of chemo or radiations therapy.

Advantages of silicone adhesives

Silicone adhesives balance adequate adhesion levels with wide range of skin types. It has low negative impact to peel surface; it doesn't stick to hair surfaces, so rarely pulls out hair during removal, and has depression affinity to attract expressionless cells, which helps in minimizing infection.

Below are examples of some suitable devices for silicone agglutinative record usage:
