Technical Application Solution:
Heat-activated AFB for Rubber Extrusions

Rubber extrusions are used for sealing and gasketing a broad range of items, including appliances, industrial enclosures and recreational vehicles. To secure these materials to substrates, OEMs are often moving from mechanically fastened designs to tape secured solutions. As a result, they reduce tooling costs and design complexity, plus obtain slimmer profiles. In this instance, Avery Dennison heat-activated AFB tape was used instead of traditional pressure-sensitive adhesive (PSA) tape its strong bond with gap filling ability. These products feature a heat activated adhesive on the side laminated to the extrusion via exposure to a heat source, while the other side has a PSA to bond to the end use substrate. The acrylic foam core provides thickness, required for bonding rigid materials, and strength, for resisting strong shear forces and harsh environments.
