In the global new energy storage industry, covering household energy storage, industrial & commercial energy storage and large-scale grid-connected energy storage systems, energy storage battery packs act as the core energy storage carrier, and their sealing, shock absorption and safety protection directly determine the operational stability, service life and safety of the whole energy storage system. Unlike vehicle-mounted power batteries, energy storage battery packs mostly operate in outdoor, semi-outdoor and long-term static environments, facing harsh conditions such as extreme temperature fluctuations, prolonged UV exposure, high humidity and rain erosion. Energy storage battery pack silicone foam is a professional sealing and cushioning component specially developed for energy storage scenarios, integrating high-standard waterproofing, flame retardancy, weather resistance and shock absorption functions. Tengye provides high-performance energy storage battery pack silicone foam, manufactured with battery-grade silicone raw materials and precision foaming technology, to deliver all-round reliable protection for energy storage battery packs and adapt to long-term harsh operating environments.
Premium Silicone Material & Energy Storage-Optimized Foaming Process
Our energy storage battery pack silicone foam adopts imported high-purity battery-grade silicone raw materials, with a halogen-free, low-smoke and non-toxic environmental protection formula, and the formula is specially optimized for the long-term operating characteristics of energy storage battery packs. We adopt advanced closed-cell foaming process to form a uniform and dense porous internal structure, balancing soft flexibility, high resilience and durable sealing performance, eliminating material defects that may damage energy storage cells and circuit systems.
This professional silicone foam features an ultra-wide operating temperature range of -60℃ to 230℃, maintaining stable physical properties even under long-term high-temperature exposure or extreme low-temperature freezing in outdoor energy storage scenarios, without hardening, cracking, softening or deformation. It has outstanding weather resistance, effectively resisting prolonged UV radiation, ozone erosion, high humidity and rain corrosion, and also boasts excellent chemical resistance, preventing corrosion from battery electrolyte, dust and acidic alkaline substances. All products comply with RoHS 2.0, REACH, UL 94 V-0 and other international certifications, fully meeting the strict safety and environmental protection standards of the global energy storage industry, with authoritative third-party test reports (SGS/Intertek) available for verification.
Core Performance Advantages for Energy Storage Battery Packs
Our energy storage battery pack silicone foam is targeted at the pain points of energy storage scenarios, breaking through the limitations of traditional sealing materials, with optimized performance to meet the long-term protection needs of energy storage battery packs, ensuring the safety and stability of energy storage systems:
-
High-Grade Waterproof & Dustproof: The dense closed-cell structure achieves IP67-IP68 protection rating, effectively blocking rainwater, moisture, dust and sediment from invading energy storage battery packs, avoiding short circuits, corrosion and capacity attenuation of internal cells and circuit boards caused by moisture intrusion, adapting to outdoor and high-humidity energy storage environments.
-
Ultra-High Flame Retardancy: Meets UL 94 V-0 top-level flame retardant standard, self-extinguishing immediately after leaving the fire, no molten dripping and no toxic gas release, effectively blocking the spread of fire and eliminating fire safety risks of large-capacity energy storage battery packs.
-
Superior Weather & Aging Resistance: Specially optimized for long-term outdoor use, it resists prolonged UV radiation, temperature cycles and environmental erosion, maintaining stable sealing and resilience for 10-15 years, far exceeding the service life of ordinary foam materials, reducing the maintenance and replacement costs of energy storage stations.
-
Excellent Shock Absorption & Cushioning: The porous foamed structure efficiently absorbs vibration and impact during transportation and installation, reducing stress on energy storage battery pack shells and internal modules, preventing structural looseness and cell damage, ensuring stable operation after long-term static placement.
-
Low Compression Set & Durable Resilience: Boasts exceptional rebound performance, with a compression set of ≤5% after long-term compression, retaining tight fitting and sealing effect under sustained assembly pressure, avoiding sealing failure caused by permanent deformation in long-term use.
-
Battery-Friendly & Easy Installation: The material is neutral and non-corrosive, will not react with energy storage battery cells, shells and circuit components; lightweight and soft, it fits irregular gaps and curved surfaces of battery packs, compatible with automated assembly and manual installation, improving construction efficiency.

Precautions for Use
To ensure the performance and service life of energy storage battery pack silicone foam, and give full play to its sealing and protection effects in long-term outdoor use, please abide by the following guidelines during installation and use:
-
Before installation, thoroughly clean the bonding surface of energy storage battery pack shells and components to keep it dry, smooth, free of oil, dust, burrs and impurities, ensuring a tight fit between the foam and the battery surface.
-
Control the compression ratio reasonably during installation, generally controlled at 30%-50%, avoid excessive compression to prevent permanent deformation of the foam, which will affect sealing, shock absorption and weather resistance performance.
-
Store the product in a cool, dry and ventilated environment before installation, avoid long-term exposure to strong sunlight, high-temperature heat sources and open flames, and keep away from flammable, explosive and corrosive chemicals to prevent premature aging.
-
Select the appropriate product specifications, thickness and weather resistance grade according to the actual installation environment (outdoor/indoor), capacity of energy storage battery pack and industry safety standard requirements.
-
During transportation and installation, avoid sharp scratches and heavy pressure on the foam, so as not to damage the foam structure and affect its normal long-term protection performance.
