How to Solve the Allergy Problem in Medical Industry Applications

A well-known medical device company faced severe challenges in developing a new medical adhesive patch: the existing adhesive caused skin rashes, itching, and other allergic reactions in trial users, failing to meet ISO 10993 biocompatibility requirements. The product launch was stalled, and the client urgently needed a solution that simultaneously offered extreme hypoallergenicity, reliable adhesion, breathable comfort, and compliance assurance.

We introduced a series of medical-grade hot melt adhesive solutions:

1. Selected high-purity medical-grade raw materials and hydrogenated tackifying resins to eliminate common allergens;
2. Employed an innovative high-molecular-weight block copolymer formula to reduce small molecule migration and avoid the use of latex and allergy-prone synthetic materials;
3. Provided a full set of ISO 10993 biocompatibility test reports (including skin irritation, sensitization, and cytotoxicity tests) to facilitate rapid registration;
4. Balanced breathability and adhesive performance through microporous structure design, ensuring user comfort.

This solution successfully helped the client achieve a “low sensitization” breakthrough, with all allergy tests for the new patch returning negative results. The product’s “ultra-low sensitization” feature became a core selling point, significantly enhancing brand competitiveness and premium pricing capability, successfully capturing the market, and fostering a long-term strategic partnership between both parties.
