Adhesive expertise to drive innovation 

tesa developed a new Seal Line tape to help a European OEM strengthen sales and enhance supply chain resilience through diversified sourcing. The OEM’s reliance on outdated specifications was limiting adoption of modern adhesives by its partners. By sharing our expertise on real-world seal application requirements with both the OEM and the seal manufacturer, we identified relevant performance data and created new adhesive solutions that met today’s technical and supply chain needs.

This collaboration shows that tesa is more than just a tape manufacturer — we’re a partner helping you get your seals into production efficiently.

Outstanding technical performance

Car doors are opened and closed thousands of times over their lifetime, in freezing conditions and on hot summer days. For the door seals to withstand this high, repeated stress over many years, manufacturers need high-performance adhesive solutions that stand the test of time.

tesa® ACXplus 74712 achieved >100,000 slam cycles in door seal testing, and compliance with TL52223, for assurance of its high-quality design and performance.
