The deep integration of China's rubber products industry and energy storage industry is transforming from a traditional supplier of seals to a provider of core material solutions for new energy equipment. In power batteries and energy storage systems, ethylene propylene diene monomer (EPDM) and chloroprene rubber (CR) have become mainstream materials, widely used in battery pack seals, energy storage container shock absorbers, and insulation layers, meeting strict standards such as IP67 protection, UL94 V-0 flame retardant, electrolyte corrosion resistance (volume change rate ± 25%), and wide temperature range operation from -40 ℃ to 120 ℃. GB/T 37996-2019 provides a unified technical specification for the industry. The thermal conductive silicone pad and fluororubber sealing ring work together to improve thermal management efficiency and reduce the risk of thermal runaway. Top enterprises accelerate their layout: Haida Group relies on sealing and shock absorption technology to enter the energy storage supply chain; Huaqin Rubber and Ningde Times jointly built a 30MW/60MWh industrial and commercial energy storage project; Zhongce Rubber has built a 20MW/40MWh household energy storage system to achieve a closed-loop green energy consumption; Sailun Group improves manufacturing energy efficiency through intelligent storage and circulating water cooling patents. The industry is moving from 'cost driven' to 'material structure system' integrated innovation. The market size of rubber products for energy storage is expected to exceed 8 billion yuan by 2025, becoming a key invisible force supporting the safe and stable operation of the new power system.
