3M™ Urethane Foam Tape 4317

Seals Out Moisture, Dust and Drafts

3M™ Urethane Foam Tape 4317 is 3/8 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 4317 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.
