Gaskets are substrates, typically foam, rubber or paper, that act as an interface or seal between two surfaces. They are found throughout industry, but are especially common in electronics, transportation, fluid handling and appliances. Their assembly requires resistance to a number of fluids, high adhesion to difficult-to-bond surfaces, and fast and easy application.
Because gaskets are often held in place with pressure and friction (O-rings, for example) a true “bond” may not be required. In applications such as these, adhesive bonded gaskets are most commonly placed in compression stress.
Converters can help you determine which 3M products best suit your needs, then provide them in the shape and format you require.
3M tapes, adhesives, sealers and fasteners offer a range of options for gasket attachment applications, whether you need to permanently bond panels to rigid frames, maintain elasticity for dynamic loads or allow for expansion when temperatures change. Use this list as a relative comparison of product performance.
