How are polymers activated?

• A. Pressure
• B. Solar radiation
• C. Heat—warm barrier prior to application
• D. Mechanical grinding

Answer: (C)

Adhesive polymers used in ostomy barriers are designed to respond to heat. Warming the barrier causes the polymer to soften and become tackier, which improves its ability to wet the skin, fill in micro‑irregularities, and form a strong, airtight seal. This activation leads to better adhesion and reduces the chance of leakage. Simply applying pressure won’t fully activate the tackiness, while solar radiation would not be used to activate the adhesive and could damage the material, and mechanical grinding would ruin the barrier. So warming the barrier before application is the intended method to activate the polymer’s adhesive properties.
