Which expert could list the performance parameters of medical pressure-sensitive adhesives for me? Thank you
A colorless or pale yellow viscous liquid formed by the terpolymerization of acrylic acid, higher acrylate esters, and functional acrylates. It has good pressure-sensitive adhesion. When applied to polyethylene or polyurethane films, it exhibits a peel strength of ≥20 N/25 mm for glass at 180° (23°C), and adhesion retention (peel-off time) of ≥150 s at 40°C. After undergoing biological tests such as cytotoxicity, skin irritation, systemic toxicity, hemolysis, and allergy testing, it meets the requirements for Class II medical products, and can be used as an adhesive material for medical adhesives, medical tapes, surgical films and wound sealing strips, sanitary pads, diapers, etc. Main testing indicators: ① Pharmacological properties ； ② Drug efficacy ； ③ Peel force (also known as adhesion force, peel strength) ； ④ Quick adhesion (or surface quick adhesion wetting capacity) ； ⑤ Cohesion.
Thank you :) :) :)
