Driver: Rising power density in charger electronics driving demand for high-thermal-conductivity potting materials
Rising power density in EV charger electronics, driven by higher switching frequencies, compact power module designs, and the adoption of SiC and GaN-based devices, is significantly increasing localized heat generation within chargers. Conventional encapsulants are unable to dissipate this concentrated heat effectively, leading to performance derating and reliability risks. As a result, charger manufacturers are increasingly adopting high thermal conductivity potting compounds to maintain thermal stability, electrical insulation, and long-term operational reliability under continuous high load conditions.
Restraint: Regulatory tightening on flame-retardant chemistries and additive bans
Regulatory tightening on flame-retardant chemistries and the restriction of certain halogenated and additive systems are limiting the formulation flexibility of potting compounds used in EV chargers. Compliance with evolving chemical regulations increases reformulation and qualification costs, particularly for high-performance materials used in DC fast chargers. These constraints can slow product approvals and delay time to market for new potting solutions.
Opportunity: Commercialization of high-thermal-conductivity silicone potting for WBG-enabled power modules
The increasing adoption of wide bandgap (SiC and GaN) power devices in EV chargers is creating strong demand for silicone potting compounds with significantly higher thermal conductivity. These materials enable efficient heat dissipation while maintaining electrical insulation and mechanical flexibility in high-frequency, high-voltage power modules. Commercializing such advanced silicone systems offers material suppliers an opportunity to secure design wins in next-generation DC fast chargers.
Challenge: Circularity and end-of-life issues limiting high-performance polymer choices
Circularity and end-of-life regulations are increasingly restricting the use of permanent, cross-linked potting compounds in EV chargers, as they complicate material recovery and component recycling. High-performance polymers with strong adhesion and thermal stability are particularly difficult to remove or reprocess at the end of life. This creates a technical challenge for manufacturers to balance durability, safety, and recyclability without compromising charger performance.

Electronic Potting Compound Market for EV Charger, By Charger Type
DC chargers are expected to lead the market for EV charger due to their high operating voltages and power levels, which demand potting materials with superior dielectric strength and thermal conductivity to protect dense power electronics. Additionally, the compact design of DC fast charging modules increases heat concentration, driving higher potting compound usage per charger.
Electronic Potting Compound Market for EV Charger, By Setup Type
Stationary (public) chargers are expected to lead the market for EV charger because high-power DC fast chargers deployed in public locations require heavy encapsulation to withstand continuous operation, high thermal loads, and outdoor environmental exposure. In addition, public chargers typically integrate larger power modules and higher redundancy levels, resulting in significantly higher potting compound consumption per installation compared to residential systems.
Electronic Potting Compound Market for EV Charger, By Material Type
Silicone is expected to lead the market for EV charger due to its inherent ability to maintain dielectric strength and flexibility under continuous high-temperature operation in DC fast-charging modules. Its low modulus and resistance to thermal cycling reduce stress on power electronics and solder joints, making it well-suited for high-voltage, high-power charger architectures.
Electronic Potting Compound Market for EV Charger, By Curing Technology
Thermal-cured technology is expected to lead the market for EV charger due to its ability to deliver high cross-link density, resulting in superior dielectric strength and long-term thermal stability for high-voltage DC charger modules. Additionally, thermal curing enables controlled processing of thick potting layers required in high-power chargers, ensuring consistent performance and reliability under continuous high-temperature operation.
Electronic Potting Compound Market for EV Charger, By EV Component
EV battery cells are expected to drive the market for EV charger, as higher-energy-density chemistries and tighter cell-to-cell spacing increase the need for thermal management and electrical insulation. In addition, growing regulatory and OEM focus on mitigating thermal runaway propagation is driving higher potting compound usage at the cell and module level.
REGION
The Asia Pacific is projected to record the highest growth in the electronic potting compound market for EV chargers during the forecast period.
The Asia Pacific is expected to witness the highest growth in the market for EV charger due to the rapid expansion of high-power DC fast charging networks in China, Japan, and South Korea, which require advanced thermal and electrical insulation materials. The region's strong domestic manufacturing base for power electronics is increasing local sourcing of potting compounds for charger modules. In addition, faster adoption of 800 V charger architectures and stricter national safety certifications are driving higher potting compound consumption per charger.
ELECTRONIC POTTING COMPOUND MARKET: COMPANY EVALUATION MATRIX
In the electronic potting compound market for EV charger, Henkel Corporation (Star) leads through its broad, EVSE-qualified portfolio of high-thermal-conductivity and high-dielectric potting solutions, supported by strong OEM relationships and global application engineering capabilities.
