We have a wide range of high-performance silicone materials designed to support the transfer and release of heat generated from high-current charging gun cables, including:
 

• Silicone heat transfer fluid
• High-consistency silicone rubbers (HCR)
• Liquid silicone rubbers (LSR)
• Sealants and adhesives
• Encapsulants and pottants
• Gap fillers

These technologies can be used in coolant tubes and charging gun heads, as well as the interior, exterior, handle and connector of charging ports.   

Interiors of printed circuit board (PCB) modules, charging gun connectors and charging housing cabinets contain components such as capacitors, semiconductors and magnetic devices, which all are sensitive to environmental contamination (e.g., ingress of dust, water, salt spray, etc.). These interiors also contain power devices with high heat output.

DOWSIL™ silicone conformal coatings, pottants and encapsulants can be used in rigid and flexible circuit boards, connector pin sealing, sensitive components, and other fine-pitched designs to meet the varied reliability standards of EV charging and help protect these structures from the environment.

Charging guns in public settings can face harsh weather conditions. To endure these challenges, the thermoplastics used in the housing of the charging gun and other external handle parts must be modified with additives that extend lifespan.
 

PARALOID™ Impact Modifiers enhance toughness and impact resistance, even at low temperatures, across a range of engineering resins used in EV charging guns. Additionally, our modifiers enable processability and mechanical recyclability, supporting their reuse in other demanding applications.
