In new energy battery boxes, energy storage cabinets, new energy vehicle casings, electrical control boxes and industrial high-temperature equipment, cabinet flanges, panel gaps and box cover joints need convenient, stable and long-lasting sealing materials. Single sided adhesive silicone foam seal strip is a closed-cell silicone foam sealing part with single-sided high-strength adhesive coating, combining compressible foam body, one-sided self-adhesive layer and protective release film. It eliminates secondary gluing and mechanical fixing, supports one-step rapid pasting on assembly lines, and realizes integrated functions of waterproof, dustproof, shock absorption and heat insulation. Tengye produces high-performance single sided adhesive silicone foam seal strips through integrated extrusion foaming and automatic single-sided gluing lamination process, providing efficient and reliable sealing solutions for all kinds of equipment shells and cabinet structures.
Silicone Foam Raw Material & Single-Sided Gluing Integrated Process
Our single sided adhesive silicone foam seal strip adopts high-purity imported silicone raw materials, optional halogen-free low-smoke flame retardant formula, non-toxic, low odor and eco-friendly, specially optimized for long-term closed high-temperature alternating working environments. We adopt one-step closed-cell continuous extrusion foaming technology to form uniform and fine honeycomb pore structure inside the strip, with smooth and compact surface, no powder falling off or delamination after long-term repeated compression. One side is uniformly laminated with high-adhesion acrylic pressure-sensitive adhesive, matched with PET release liner for easy tearing. The adhesive has strong adhesion to aluminum alloy, steel plate, plastic, coating and other cabinet surfaces, no residual glue after disassembly. Foam density, hardness, cross-section shape and adhesive temperature resistance grade can be customized according to customer gap size and assembly requirements.
This professional single sided adhesive silicone foam seal strip has an ultra-wide operating temperature range of -60℃ to 230℃. It can maintain stable soft elasticity and reliable bonding performance under long-term high-temperature baking, cold and hot alternating cycles and outdoor UV irradiation. No hardening, shrinkage, glue failure or elasticity loss occurs after years of use. The material has excellent chemical inertness, resisting corrosion from battery electrolyte, engine oil, weak acid and alkaline cleaning agents, with outstanding ozone aging and weather resistance, suitable for indoor and outdoor harsh working conditions. All products fully comply with RoHS 2.0 and REACH standards, UL 94 V-0 flame retardant grade is optional, complete SGS and Intertek third-party test reports on sealing, temperature resistance and adhesion can be provided for export certification.
Core Performance Advantages of Single-Sided Backed Foam Seal Strip
Aiming at the pain points of complex installation, easy falling off and complicated operation of ordinary non-adhesive sealing strips, our single sided adhesive silicone foam seal strip has comprehensive performance upgrades, perfectly matching mass automatic assembly and cabinet maintenance sealing scenarios:
-
Single-Sided High-Strength Adhesive, Fast Assembly: Single surface coated with industrial high-viscosity pressure-sensitive adhesive with complete release film. Just tear off the liner and paste it on the flange surface directly, without screws, rivets or additional glue, greatly shortening assembly time and improving production line efficiency.
-
Excellent Airtight Waterproof & Dustproof Effect: Soft and compliant closed-cell foam fits irregular gaps tightly to form a complete sealing barrier, reaching IP67-IP68 protection grade, effectively blocking rainwater, moisture, dust and fine particles from entering the cabinet to avoid circuit short circuit and metal corrosion.
-
Stable High & Low Temperature Resistance: Long-term stable use at -60℃~230℃, the adhesive layer and foam body will not fail under low-temperature cold start and continuous internal high-temperature heat accumulation, and the sealing performance remains stable after repeated cold and hot impact cycles.
-
Low Compression Set & Permanent Sealing Stability: Compression set ≤5%, no permanent deformation after long-term cabinet door clamping and frequent opening and closing. It can fully fill the gap for a long time without air leakage and water seepage failure.
-
Vibration Absorption & Noise Reduction Buffer: Porous foam structure absorbs vibration impact generated by vehicle driving and equipment operation, reduces metal collision noise inside the cabinet, and prevents loose connection and damage of battery modules and electronic components.
-
Optional UL 94 V-0 Halogen-Free Flame Retardant: Customizable flame retardant formula, self-extinguishes quickly after leaving open flame, no molten dripping and no toxic smoke release, effectively blocks flame spread to meet the safety requirements of new energy battery cabinets.
-
Non-Corrosive & Long Service Life: Neutral chemically inert foam and non-corrosive adhesive, no chemical reaction with aluminum, steel, plastic cabinet shells and circuit boards; strong anti-ultraviolet and anti-aging performance, stable comprehensive performance for 8-12 years indoors and outdoors.

Precautions for Use
To fully maintain adhesion, airtight sealing and shock absorption performance, extend service life and ensure long-term cabinet protection effect, please follow standardized operation specifications during installation, use and storage:
-
Before pasting, thoroughly wipe the cabinet flange and contact surface to keep it dry, smooth, free of oil, dust, burrs and rust impurities, so as to maximize the bonding strength of the adhesive and avoid early peeling.
-
Tear off the release film evenly during installation, avoid excessive stretching and sharp metal scratching to prevent damage to the internal closed-cell pore structure and reduce sealing performance.
-
Reasonably control the cabinet compression gap, keep the compression ratio between 30%-50%, avoid long-term over-compression leading to permanent deformation and loss of tight sealing effect.
-
Store the finished rolls in a cool, dry and ventilated warehouse before installation, keep away from high-temperature heat sources, open flames and corrosive chemicals to prevent adhesive aging and foam performance decline.
-
Select the corresponding thickness, density, adhesive grade and flame retardant level according to the actual internal operating temperature, surface material and service environment of the cabinet to meet the required sealing standard.
-
Regularly check the adhesion and fitting state of the sealing strip during equipment maintenance, and replace aged, warped and peeled strips in time to maintain the waterproof, dustproof and heat insulation protection performance of the cabinet.
