3M™ Urethane Foam Tape 4314, Charcoal, Gray, 3/4 in x 18 yd, 250 mil, 12 Roll/Case

Seals Out Moisture, Dust and Drafts

3M™ Urethane Foam Tape 4314 is 1/4 in. thick, comprised of a soft conformable, low-density, open-cell foam with a pressure sensitive acrylic adhesive on one side. The adhesive is protected by a silicone treated paper liner. It offers excellent cushioning characteristics while providing high absorbency to seal out moisture, dust and drafts. It can perform under a wide range of temperatures. Special note: Extra care should be taken when handling to avoid damaging tape.

Recommended Applications

Cushion and dampen sound in electronics such as printers, keyboards, computers, aircraft lights and automotive dashboards Register covers Recessed lighting

Door, window and cabinet seals

Excellent Shear Holding Strength with 3M™ Adhesive 430

3M™ Urethane Foam Tape 4314 features 3M™ Adhesive 430. This pressure sensitive, modified acrylic adhesive provides high initial quick-stick to a variety of surfaces and substrates. It has an excellent chemical resistant and shear holding strength, even at elevated temperatures. Adhesive 430 is designed to perform at temperatures up to 180°F (82°C) in the short term and 150°F (70°C) long term.

Protect Sensitive Components

The adhesion of 3M™ Single-Coated Foam Tapes is typically satisfactory within 20 minutes and continues to build with additional time. The adhesive is protected by a thick, silicone treated paper liner and has a firm, high-density foam. This design offers an attractive and clean appearance after application.

What is Open Cell Foam?

Open cell foams are commonly used between component panels where a degree of separation is needed to dampen or prevent vibration, as a thermal insulation barrier and to protect against contamination, but where a measure of airflow is still necessary, such as with electronic components where air flow helps keeps components cool.
