In 2025, the global production of Epoxy Encapsulant Material for Automotive reached approximately 98,100 tons, with an average global market price of around US$5-US$50/kg. In the same year, the global total production capacity of Epoxy Encapsulant Material for Automotive reached 122,600units. The industry average gross profit margin of this product reached 36%.Epoxy Encapsulant Material for Automotive refers to a polymer material system formulated with epoxy resin as the matrix and the addition of curing agents, fillers, and functional additives. It is used for the overall encapsulation and sealing of automotive electronic and electrical components. Its main functions are to provide insulation protection, mechanical support, waterproofing and dustproofing, resistance to high and low temperature shocks, and vibration resistance. It is widely used in key components such as electronic control units (ECUs), power modules, sensors, motor controllers, and on-board charging systems. After curing, this material forms a three-dimensional cross-linked structure, possessing excellent electrical properties and chemical stability, making it one of the core encapsulation materials ensuring the long-term reliable operation of automotive electronics in complex environments.

The epoxy encapsulant material for automotive industry chain can be divided into three main segments: upstream raw materials, midstream material manufacturing, and downstream applications. The upstream segment mainly includes chemical raw materials such as epoxy resins, curing agents, fillers, and additives. The midstream segment comprises formulation design and material manufacturing companies, responsible for material modification, thermal conductivity/flame retardant performance optimization, and reliability verification—the core of technology and added value. The downstream segment covers the automotive electronics supply chain, OEMs, and new energy electric drive system manufacturers, primarily used in the electronic systems of traditional fuel vehicles and the three-electric systems of new energy vehicles. The industry chain as a whole is characterized by deep integration of chemical materials and automotive electronics, long customer certification cycles, and high technological barriers.

With the accelerating trends of automotive electrification, intelligentization, and high voltage, especially the widespread adoption of new energy vehicles (EVs) and 800V high-voltage platforms, the demand for highly reliable, highly thermally conductive, and high-temperature resistant potting materials is rapidly increasing. This is driving the development of epoxy potting materials towards high thermal conductivity, low stress, low water absorption, high temperature resistance, and environmentally friendly halogen-free flame retardancy. Simultaneously, SiC power devices, autonomous driving control systems, and on-board charging modules place higher demands on material performance, driving the upgrading of high-end formulations. Coupled with the continued increase in the value of global automotive electronics and the trend of supply chain localization, this field will maintain steady growth in the future. However, it also faces challenges such as raw material price fluctuations, stringent long-term reliability verification, and competition from alternative materials (such as silicone and polyurethane). Overall, epoxy potting materials for automobiles belong to a high-growth functional materials sub-sector driven by new energy and automotive electronics.
