The core parameters of medical face adhesives include tack, holding power, and peel strength. Model 9889 meets high-performance standards for tack, maintaining stable adhesion even in dynamic environments-such as during patient movement. Holding power tests demonstrate that the adhesive remains securely in place for over 24 hours at a temperature of 40°C. Furthermore, its peel strength is carefully controlled within a safe range to prevent skin injury during removal. Additionally, the product has successfully passed specialized testing-including the national standard GB/T 4851-2014-ensuring that it is non-cytotoxic and causes no skin irritation.
The Model 9889 medical face adhesive utilizes PE (polyethylene) as its substrate. This material is characterized by its excellent flexibility and high chemical stability, making it suitable for direct contact with the skin. The product features a three-layer structure: a release liner on the top, a PE substrate coated with medical-grade pressure-sensitive adhesive in the middle, and a protective film on the bottom. The pressure-sensitive adhesive achieves adhesion through intermolecular forces, allowing for rapid bonding without the need for heat or solvents, and leaves minimal adhesive residue upon removal.
