Bonding to foams is necessary in a variety of industries, from furniture and building to automotive. The best adhesive for foam will depend on the type of foam you’re using and the surface you’re bonding it to. Like every other material, foams have a surface energy, which affects adhesion. Very low surface energy (LSE) foams, like polyethylene or polypropylene, will require different adhesives than comparatively higher surface energy (HSE) foams, like polyester, polyurethane or PVC.
The surface energy of the material to which you will be bonding the foam is also an important consideration, be it fabric, metal, powder coated paint, other foam or something else. Environmental conditions and bond stress should also be considered when choosing an adhesive.
When bonding relatively high surface energy HSE foams, we suggest you consider the following materials:
For LSE foams, which are generally more difficult to bond to, you should consider adhesives specifically made for bonding this type of material. You will recognize them by their suffix of LE:
If you are unsure which adhesive would best suit your project, you are welcome to consult our knowledgeable team who can make a material recommendation based on your specific use. We recommend you test adhesives in situ to ensure they perform to your specifications.
