What is Gasket Tape?

Gasket tapes are adhesive backed foam or closed cell sponge supplied in rolls slit to customer-specified width. End users cut the gasket tape to length as needed, peel the backing and bond in place. Gasket tape goes by many names including strip gaskets, foam gasket tape, roll gasket, Strip-N-Stick® or “strip and stick”. Common applications include large enclosure gaskets, door gaskets, high temperature masking, NEMA panel gaskets and cushioning strips.

HT-800 Gasket Tape

HT-800 silicone foam is UL recognized for UL 50, UL 50E (periodic recompression and continuous compression), UL 508, UL 1571, UL 1572, and UL 94V-0. This makes HT-800 ideal for outdoor lighting gaskets and NEMA enclosure gaskets. HT-800 silicone foam and the closed cell silicone sponge used for 400FR meets 21 CFR 177.2600 suitable for indirect food contact.

Strip-N-Stick® Gasket Tape

Saint-Gobain Strip-N-Stick is not currently listed for UL 50/E however it is widely used for NEMA enclosures and high temp masking applications. The closed cell silicone sponge is tougher and has a wider temperature range than silicone foam. SNS-100S is provided with a silicone adhesive allowing for a wider operating temperature (-100° to 500°F).

Gasket Tape Material Considerations

  • Indoor Applications – Dust and light water splashing, most gasket tapes can be used.
  • Outdoor Applications – Dust, rain, snow, and hose down require closed cell foam or closed cell sponge.
  • Spec Requirements – NEMA 4, NEMA 4X, IP64, IP65; material has to be functional with design but no material qualifications needed. UL 50E, UL 94; material has to be UL recognized (yellow card).
  • Bonding Surface – Powder coats and certain plastics may require high strength adhesive.
  • Temperature – SNS-100S offers a very wide temperature range and HT-800 Gasket tape is available in certain thicknesses with 3M 350 series adhesive.
  • Compression Set and Stress Relaxation – Gasket tapes offered by Stockwell Elastomerics offer very good resistance to compression set and stress relaxation making them ideal for enclosure gaskets.
  • Flame Rated Foam Tape – Silicone foam materials typically meet UL 94V-0, HT-800 foam also meets FAR 25.853 requirements.
  • Water Sealing – Aggressive wash down requirements such as IP64, IP65, IP66, NEMA 4, NEMA 4X, and UL 50 type 4 may require bonded corners to prevent the ingress of pressurized water.

Common Applications

Gasket Tape / Strip Gasket Material
  • Telecommunication enclosure gaskets, enclosure door gaskets
  • LED lighting gasket, outdoor water sealing
  • LED light leak gasket, indoor UL 94V-0
  • Masking for large composites
  • HVAC, high temp foam gasket
  • HEPA filter gasket
  • Large gasket (where single piece is cost prohibitive)
