About Foam

Super-Cushioning Polyethylene Foam Sheets and Strips

Also known as Ethafoam, these polyethylene foam sheets and strips are widely used in packaging applications to absorb shock and damp vibration. Polyethylene foam offers better resistance to chemicals than polyurethane foam and is also superior when insulating packaged objects from external temperatures. Foam has closed-cell construction, which restricts water, air, and gases from being absorbed.

Foam with ultra-smooth texture has a sleek surface that's easy to wipe down.

Static-Control Super-Cushioning Polyurethane Foam Sheets

Cushion electronic components from impact as you protect them from electrostatic shocks during shipping and storing. This open-cell polyurethane foam withstands more impact than closed-cell polyethylene foam, but is not as good for insulating items from external temperatures. The open-cell construction also means water, air, and gases can be absorbed.

Treated with additives, antistatic foam will not generate static charges. Its antistatic properties will diminish over time, however, so it’s commonly used for one-time shipping applications. This foam is pink to identify it as antistatic.

Static-Control Chemical-Resistant Polyethylene Foam Sheets

Conductive

Protect electronic components from electrostatic shocks and chemicals while safeguarding them from bumps and drops during shipping and storing. This closed-cell polyethylene foam is more chemical and puncture resistant than open-cell polyurethane foam, but is not as impact resistant. It’s also great for insulating items from external temperatures. The closed-cell construction means it won’t absorb water, air, and gases.

Conductive foam safely diverts static charges away from parts, and does not generate static electricity. Containing carbon, it keeps its conductive properties, so it’s reusable and good for long-term storing applications.
