In the new energy power battery and energy storage storage industry, battery packs serve as the core energy storage unit, and their internal sealing, shock absorption and safety protection directly determine the operational stability, service life and safety performance of the whole battery system. Battery pack silicone foam is a professional sealing and cushioning component specially developed for battery pack assembly, aiming to solve the problems of water ingress, dust intrusion, vibration damage and fire risks in complex operating environments. Tengye provides high-performance battery pack silicone foam, manufactured with battery-grade silicone raw materials and professional foaming technology, to deliver all-round reliable protection for battery packs.
Battery-Grade Silicone Material & Precision Foaming Process
Our battery pack silicone foam adopts imported high-purity battery-grade silicone raw materials, with halogen-free flame-retardant formula and environmental protection ingredients, adopting advanced closed-cell foaming process to form uniform and dense porous structure. We optimize the material ratio and foaming parameters for battery pack application scenarios, ensuring the product has excellent sealing and cushioning properties while meeting the strict safety standards of the battery industry.
This special silicone foam has a wide operating temperature range of -60℃ to 230℃, maintaining stable flexibility and resilience even under the long-term high-temperature operation of battery packs or extreme low-temperature environments, without hardening, cracking or deformation. It has strong chemical corrosion resistance, effectively resisting battery electrolyte, automotive oil, acid-base substances and other erosion, and has excellent UV resistance, ozone resistance and aging resistance, suitable for long-term use in vehicle-mounted, outdoor and industrial environments. All products comply with RoHS 2.0, REACH, UL 94 V-0 and other international certifications, non-toxic, low-smoke and pollution-free, with authoritative third-party test reports (SGS/Intertek) available for verification.
Core Performance Advantages for Battery Packs
Our battery pack silicone foam breaks through the limitations of traditional sealing materials, integrating multiple core advantages to fully meet the high-standard protection needs of battery packs, escorting the safe operation of battery systems:
-
High-Level Waterproof & Dustproof: Dense closed-cell structure achieves IP67-IP68 protection rating, effectively blocking rainwater, moisture, dust and sediment from entering the battery pack, avoiding short circuit, corrosion and capacity attenuation of internal cells and circuits.
-
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 fire spread and eliminating potential fire hazards of battery packs.
-
Excellent Shock Absorption & Cushioning: The porous foamed structure efficiently absorbs vibration and impact generated during vehicle driving, equipment transportation and operation, reducing stress on battery pack shells and internal modules, preventing structural looseness and damage.
-
Low Compression Set & High Resilience: Boasts exceptional rebound performance, with compression set ≤5% after long-term compression, retaining tight fitting and sealing effect under sustained assembly pressure, avoiding sealing failure caused by permanent deformation.
-
Long-Term Durability: Resists extreme temperature cycles, chemical corrosion and environmental aging, maintaining stable performance for 8-10 years, greatly reducing the replacement and maintenance costs of battery pack sealing components.
-
Soft & Easy Installation: Light weight, good flexibility and fit, can be closely attached to irregular gaps and curved surfaces of battery packs, compatible with automated assembly lines and manual installation, improving assembly efficiency.
Main Application Scenarios
