Silicone Gasket

Stockwell carries a wide range of materials so that we can meet the demands of most application. Over the years silicone has grown to be our core product. We are seeing more and more engineers specifying silicone products into their design because of its unique properties. Today Stockwell keeps in stock sheet good materials and compounds for custom molded silicone parts.

Key properties:
• High Operating Temperature
• Low Operating Temperature
• UV resistant
• Ozone resistant
• Excellent compression set resistance (rebound)

Silicone offerings include:
• Silicone Foam - that is UL94 V0 rated, excellent for electrical enclosure
• Closed Cell Silicone Sponge - for soft water gaskets such as IP 66, IP 67, and NEMA 4
• Solid Silicone – for water tight seals where higher closure forces are available
• Custom Molded Silicone – standard 20 durometer thru 70 durometer
• Electrically Conductive Silicone – for EMI and ESD gaskets
• Thermally Conductive – for gap pads and press pads for thermal management
• Adhesive Backed Silicone – Stockwell applies pressure sensitive adhesives (acrylic and silicone) to most materials in stock

What is kiss cutting and a kiss cut gasket?

Kiss cutting is a die cutting process where a gasket or pad is supplied rolled up on the adhesive liner. If you were able to watch the cutting process in slow motion you would see the die penetrate the gasket or pad material, then continue through the thin adhesive layer and cut partially into the adhesive liner. The gasket or pad must have a Pressure Sensitive Adhesive (PSA or “peel and stick”) backing for kiss-cutting to be possible.

Kiss cutting has several advantages over individually cut through parts. Kiss-cut gaskets the parts to be rolled up, parts on rolls are easier to handle can and can be set up neatly and dispensed in a paper towel like fashion at assembly work stations. Also, peeling the part off the release liner is considerably easier than removing the release liner from an individual part, this helps increase production throughput.

Stockwell regularly kiss-cuts gaskets and pads from solid silicone, silicone sponge, silicone foam, and Poron. Other materials include foam adhesives such as 3M VHB’s and thermal pads. Note, not all materials and parts can be kiss-cut, for more information please contact service@stockwell.com .
