Since medical hot melt adhesives directly act on the surface of the human body, the standards and requirements for this type of hot melt adhesive are very high. So, what are the specific standards?
1. Adhesion
Different people have different skin types, such as dry and oily, thick and sparse body hair, smooth and rough. Human skin has a certain degree of breathability, but it also varies in terms of oiliness, sweating ability, dryness and other types. In view of these differences, when choosing adhesives, it is necessary to ensure the firmness of the bond and excellent durability. The material itself. Sensitivity and odor.

① The peel strength of medical hot melt adhesive should not be too high: The peel degree of hot melt adhesive should be maintained within a certain range. Excessive peel strength may cause skin tension and discomfort during use. There is pain and skin damage when tearing.
② Good initial adhesion: As the material is mostly used on or around wounds, it is not advisable to press hard. Hot melt adhesive requires good initial viscosity and is easy to adhere to the skin.
3. Hypoallergens
When using medical hot melt adhesive, it is required that it will not cause skin irritation, such as redness, itching and other allergic reactions.
4. Air permeability
Medical hot melt adhesive products need to have good air permeability, which can significantly reduce the occurrence of skin allergies. Maintaining permeability during the construction process also helps the skin sweat, keeps the wound dry, and has a positive effect on accelerating wound healing.
