Video: Foam and fiber bonding emulsion products - Butterfly test
Avery Dennison Foam and Fiber bonding emulsion products are versatile pressure-sensitive tapes ideal for general purpose foam bonding applications in industries such as automotive, appliances, building and construction, transportation, and heavy equipment. These emulsion products offer ease of conversion, excellent price to performance ratio, high adhesion to low surface energy materials and excellent resistance to solvents, chemicals, plasticizers, moisture, temperature and UV light. This butterfly test demonstrates the strong lamination bond of the pressure-sensitive adhesives to foam. When the foam tears it shows that the strength of the adhesive bond is stronger than the internal strength of the foam.
