Application Areas And Technological Innovations Of Medical Hot Melt Adhesives

Application Areas

Medical Protective Equipment: Used for seam bonding in surgical gowns and ear loop fixation in medical masks. 180° peel tests show that the adhesion failure mode between the material and the nonwoven fabric is cohesive failure.

Sterilized Medical Device Packaging: As of 2024, Pupack™ products from Pumo have provided packaging solutions for pre-filled syringes in China. Their clean peel characteristics have validated packaging integrity.

Wearable Medical Devices: In dynamic adhesion tests, after simulating strenuous exercise for 8 hours, the adhesive strength remains at 9.2 N/cm², meeting the requirements for continuous ECG monitoring patches.

Technological Innovation

At the 2024 China Hot Melt Adhesive Summit Forum, the industry first disclosed UV acrylate hot melt pressure-sensitive adhesive technology. This technology forms a cross-linked network through a photocuring reaction, extending the adjustable range of medical tape peel force to 16 KN/m. Research confirms that when the storage modulus (G') of the pressure-sensitive adhesive is controlled within 3×10⁴-5×10⁴ Pa, optimized application and removal performance can be achieved.
