Our single-sided adhesive silicone foam seal strip is an integrated sealing composite material made of platinum-vulcanized closed-cell silicone foam substrate and high-temperature resistant single-sided acrylic adhesive layer. It is specially developed for new energy vehicle battery boxes, energy storage cabinets, power distribution enclosures, electronic equipment housings, industrial control cabinets, lighting and household appliances. Produced by integrated calendering composite foaming process, fully compliant with RoHS, REACH, optional UL94 V-0 flame retardant standards and industrial safety specifications. This product realizes one-step quick pasting installation, integrates IP67 waterproof & dustproof sealing, shock absorption buffering, thermal insulation and electrical insulation functions. It perfectly fills assembly gaps of all equipment shells, simplifies production line operation procedures, and provides long-term stable sealing protection for indoor and outdoor electrical and mechanical equipment.
Core Performance & Structural Advantages
It features dense and uniform closed-cell micropore foam body, flat smooth surface, consistent thickness and ultra-high soft resilience. The single-sided adhesive layer is evenly compounded without bubbles, no degumming, no residual glue after peeling, and closely fits metal, plastic, aluminum alloy and coated shells without scratching the surface. It solves the pain points of ordinary foam strips such as difficult fixing, complicated assembly, easy falling off and short service life, with exclusive single-sided adhesive integrated advantages:
- High Viscosity Temperature-Resistant Single-Sided Adhesive Layer, Efficient Quick Installation
Equipped with high-performance acrylic single-sided adhesive, strong adhesion to metal, plastic, glass, paint and other material surfaces. The adhesive maintains stable viscosity within -40℃ ~ 120℃, no glue overflow, melting or viscosity loss under long-term temperature fluctuation. Just tear off the release liner and paste directly, no extra glue, fixtures or auxiliary positioning parts needed, greatly shortening assembly time and reducing labor costs on production lines.
- IP67 Grade Closed-Cell Waterproof, Dustproof & Air-Tight Sealing
Compact fully closed-cell micropore structure completely isolates rainwater, humid air, dust, sand and corrosive gas penetration. After uniform compression and fitting, zero gap leakage, effectively avoid internal circuit short circuit, metal component rust and equipment performance attenuation caused by moisture intrusion, suitable for long-term unattended outdoor equipment operation.
- High Compression Resilience & Long-Term Vibration Buffering
Compression set ≤7%, fast full rebound after long-term continuous extrusion without permanent collapse and deformation. It absorbs vibration and impact force generated during equipment transportation and operation, buffers collision and extrusion between shell and internal modules, and protects batteries, circuit boards and precision electronic components from mechanical damage.
- Ultra-Wide Temperature Adaptability & Stable Thermal Insulation
Continuous operating temperature range: -60℃ ~ 230℃; the foam body remains soft and non-brittle in low-temperature environments, and will not soften, deform or decompose under long-term high-temperature baking. Low thermal conductivity micropore structure blocks heat transfer, reduces internal temperature rise of equipment and avoids overheating failure of electronic parts.
- Optional UL94 V-0 Halogen-Free Low-Smoke Flame Retardant Formula
Customizable flame retardant grade reaches UL94 V-0 standard, self-extinguishes rapidly after leaving fire source, no molten drips and low toxic smoke during combustion, forms a stable fire barrier to block flame spread through shell gaps, meeting high safety requirements of new energy storage and power equipment.
- Excellent Electrical Insulation & Long-Term Weather Resistance
Volume resistivity ≥10¹⁴Ω·cm, stable insulation performance to isolate leakage current and electromagnetic interference, effectively prevent short-circuit safety hazards. Added with anti-UV and anti-ozone anti-aging additives, it resists long-term outdoor sunlight, wind and rain erosion, no hardening, yellowing or cracking after 8–10 years of service life.
- Full-Spec Customization & Flexible Processing
Customizable thickness, width, length, rectangular or special-shaped cross-section, flame retardant/non-flame retardant formula as required; dimensional tolerance controlled within ±0.05mm. The soft foam body is convenient for arbitrary cutting and bending, adapting to irregular curved flanges and narrow gap installation.
- Eco-Friendly & Good Material Compatibility
Halogen-free, non-toxic, odorless and heavy metal-free, fully compliant with global environmental protection regulations. Chemically inert with metal, plastic, coating and other shell materials, no surface corrosion, discoloration or adverse chemical reactions.
Typical Application Scenarios
- New Energy Industry: Single-sided adhesive sealing gaskets for NEV battery box covers, energy storage cabinet shell seams and battery module frame gaps
- Electrical & Power Equipment: Dustproof insulating sealing strips for distribution boxes, inverter cabinets, charging pile housings and industrial control enclosures
- Electronic Communication Equipment: Gap filling, shock absorption and waterproof sealing for routers, display monitors, sensors and outdoor communication cabinets
- Lighting & Household Appliances: Weatherproof sealing for LED lamp housings, air conditioners, water heaters and kitchen equipment casings
- Industrial Automation Machinery: Anti-vibration and dustproof sealing for mechanical equipment housings, precision testing instruments and automation equipment
Precision Manufacturing & Strict Quality Control
Aiming at the demand of fast assembly and long-term stable sealing of equipment shells, we implement full-process industrial-grade quality management and multi-dimensional batch performance testing:
- Composite raw material strict screening: Platinum-cured silicone foam matched with temperature-resistant single-sided acrylic adhesive; all raw materials pass adhesion aging, high-low temperature cycle and environmental migration tests before production;
- Integrated calendering composite foaming process: Ensure uniform foam pores, consistent thickness and firm bonding between foam substrate and adhesive layer without delamination;
- Full-item batch inspection: Each batch undergoes adhesion test, waterproof sealing test, compression recovery test, flame retardant test and UV aging test, factory qualification rate up to 99.8%.
Precautions
- Thoroughly wipe and clean the bonding surface before installation to remove dust, oil stains, water stains and burrs, to ensure full adhesion and stable sealing effect;
- Do not violently stretch, twist or tear the foam strip during construction, to avoid damaging the closed-cell structure and single-sided adhesive layer, resulting in degumming and performance attenuation;
- Avoid long-term direct contact with strong acid, strong alkali and high-concentration corrosive solvents to prevent adhesive failure and foam aging;
- Store in dry, cool and ventilated warehouse, keep away from open flames and high-temperature heat sources, avoid heavy pressure stacking and direct sunlight exposure;
- Forbid continuous use beyond the rated temperature range, otherwise adhesive viscosity and foam sealing performance will drop sharply;
- Regularly check the bonding state of the strip during equipment operation, replace it in time if degumming, aging or permanent compression deformation occurs.
