Double sided foam electrical sealing tape is a high-performance adhesive tape featuring black foam with a blue liner. This versatile tape is designed with strong acrylic adhesive on both sides, providing excellent sealing and bonding capabilities. The foam material offers superior compression deformation resistance, flame retardancy, and wettability, making it ideal for various industrial and commercial applications.
The electrical sealing tape is waterproof and maintains its performance at normal temperature ranges, ensuring reliable performance in diverse environments. Its high tensile strength and no discoloration properties make it a durable choice for long-term applications.
Backed by Jiangsu Gelly Adhesive Material Technology Co., Ltd, our Double Sided Foam Electrical Sealing Tape features a black closed-cell foam carrier coated with high-strength acrylic adhesive on both sides, and is laminated with a high-visibility blue release liner for quick and precise application. The closed-cell structure provides exceptional sealing against dust, moisture, and contaminants, while the flexible foam core conforms to uneven surfaces, fills gaps, and compensates for varying thermal expansions. Operating reliably from -40°F to 300°F (-40°C to 149°C), it is the ultimate solution for electrical enclosure sealing, component mounting, and vibration damping.
Exceptional Sealing Performance: The closed-cell foam structure effectively prevents the ingress of dust, moisture, and contaminants, providing reliable waterproofing and resistance to chemicals and weathering.
Strong Adhesion: Featuring high-strength acrylic adhesive on both sides, this tape offers superior bonding strength that withstands vibration and mechanical stress, eliminating the need for mechanical fasteners like screws and bolts.
Versatile Conformability: The foam's flexibility allows it to conform to uneven surfaces and fill gaps effectively, compensating for varying thermal expansions across a wide temperature range of -40°F to 300°F.
Vibration Damping: The foam material absorbs shock and vibration, protecting delicate electronic components from mechanical stress.
Easy-to-Use Blue Liner: The high-visibility blue liner is easy to remove, allowing for quick and precise application without requiring special tools or equipment.
Electrical Enclosure Sealing: Creating permanent, watertight seals for junction boxes, control cabinets, and electrical enclosures against dust and moisture ingress.
Component Mounting: Securing busbars, panels, and electrical accessories without drilling, preserving the integrity of the enclosure.
Vibration Protection: Damping shock and vibration in electronic devices, automotive interiors, and appliance assemblies.
Gap Filling & Weather Stripping: Compensating for irregular gaps and thermal expansion in construction, HVAC, and transportation applications.

A Strong and Established Tape Manufacturer
The high-visibility blue liner serves two critical purposes. First, it makes it extremely easy for operators to see and grasp the edge of the liner for quick removal, speeding up assembly. Second, it acts as a quality-control indicator: if a piece of the liner is accidentally left behind or not removed, its bright blue color is immediately visible against the black foam and most substrates, preventing assembly errors.
Yes. The tape features a closed-cell foam structure, meaning the individual foam cells are not interconnected. This prevents water, moisture, dust, and contaminants from wicking through the tape itself. When compressed between the enclosure and the cover, it creates a permanent, watertight gasket seal.
As a general engineering rule, select a tape thickness that allows for 20% to 30% compression when the enclosure is closed. For example, if your gap is 0.8mm, a 1.0mm thick foam tape is ideal. We offer thicknesses from 0.4mm up to 2.0mm (and custom up to 5.0mm) to match your specific gap dimensions and compression requirements.
Yes. The high-strength acrylic adhesive provides a holding force of ≥48 hours, while the flexible foam core absorbs shock, vibration, and compensates for the varying thermal expansions of different materials (like metal-to-plastic). It operates reliably from -40°F to 300°F (-40°C to 149°C), making it suitable for automotive, appliance, and outdoor electrical applications.
