Foam Seals

If you need to keep water, dust, air, noise, or vibration out, foam seals can be a simple, effective solution.

Foam seals create a protective barrier between two surfaces, helping prevent liquids, gases, particles, and/or sound from passing through. Available as strips, washers, gaskets, pads, edge trims, or bespoke shapes, industrial foam seals can also provide cushioning, insulation, and protection against wear and tear. As a result, they are popular for sealing, condensation control, expansion fillers, thermal insulation and acoustic deadening.

At Polyformes, we design and manufacture custom foam seals in a range of materials, shapes, and sizes to suit your product, equipment, or application. We work with you to select the right material for your needs, ultimately delivering reliable performance regardless of your industry.

FAQs

One of the key applications for foam seals is to create a barrier to water and other non-toxic and toxic liquids. Most closed-cell foams used to manufacture foam seals have excellent hydrophobic properties, meaning they repel water rather than absorb it. Foam materials such as ZOTEK® and Plastazote® also offer excellent chemical resistance, making them well-suited to the manufacture of foam seals for the construction and automotive industries.

It’s vital that seals fit the adjoining components within a close tolerance, particularly where a barrier against liquids, gases, dust, or sound is required. Foam is one of the few seal-making materials that can be cut or formed to precise tolerances, even for more intricate fittings.

Foam seals are suitable for use in machinery, remaining functional even under extreme vibration. Closed-cell polyethylene foam also has an exceptional ability to absorb impact multiple times without losing its shape, making it the perfect material for seals where components separate and reconnect frequently or infrequently.

Foam seals are used in a variety of industries, including construction, automotive, aerospace, electronics, HVAC, and manufacturing, to seal gaps, reduce vibrations, prevent any leaks, and improve insulation. Specific materials, including ZOTEK® N, are particularly suited for manufacturing seals for demanding applications (such as aviation and aerospace sectors), providing stability whilst also allowing for compression without degradation.
