About Durometer Hardness Scales

About Rubber

Very soft and conformable, this expanded PTFE gasket tape compresses into an extremely thin profile. Use it to create a leak-resistant seal in tight-tolerance applications, such as on precision machinery. This tape is chemically inert, except to molten alkali metal and elemental fluorine.

Gasket tape that is made with FDA-listed material is for use with food and beverage.

EMI/RFI Shielding Gaskets

These gaskets absorb electromagnetic interference (EMI) and radio frequency interference (RFI) to prevent inaccurate signals, flickering displays, and other electrical problems. They compress to fill gaps and complete a grounding path around doors and access panels.

Sheets work well between two flat surfaces.

Polyurethane foam gaskets are covered with a conductive nickel/copper braided fabric. A nonconductive adhesive holds them in place. To protect sensitive equipment, they block at least twice as much interference as urethane foam gaskets. They meet UL 94 V-0, so they self-extinguish within 10 seconds if they catch fire and won’t spread the fire by dripping. Cut these gaskets to length with scissors.

High-Temperature Silicone Rubber Sheets, Bars, and Strips

Also known as polysiloxane, this silicone rubber offers good resistance to ozone and salt water. Softer durometer rubber has better conformability; harder durometer rubber is more wear resistant.

For adhesive-back sheets and strips that are FDA compliant, the silicone rubber meets the standard, but the adhesive does not.

Magnetic Wear Strips

Easily attach, move, and replace these magnetic wear strips on metal surfaces to minimize friction—simply press them on and peel them off as needed. Often found on conveyor systems and chutes, use these strips where friction between two parts or materials is wearing down equipment to extend equipment life. All of these strips have an extra-hard rating to withstand high levels of impact. They are flexible enough to bend around a curve. They're also nonmarking.
