Momentive Silicone | EV Cable and Connectors

The Challenge For EV Cable and Connector Manufacturers

Thermal management for automotive temperature systems is a way to transfer or insulate heat. Rapid charging stations require an optimal flow of energy to keep up with consumer travel expectations, with some charging stations able to charge EV batteries to 80% in about 30 to 45 minutes. These direct current (DC) stations are the required infrastructure for rapid charging. This means charging cables and EV under-the-hood cables and connectors must handle this highest level of charging stations. DC charging delivers outputs of 15 kW to 350 kW compared to alternating current (AC) charging, considered level 1 and 2 EV charging. To withstand that type of direct electrical flow, the insulation material for both the vehicle and the station must offer the highest level of performance, safety, and efficiency.

In addition, the overall vehicle weight must be reduced by replacing steel and iron components with lightweight materials, such as polymer composites, alloys, or carbon fibers. Lightweighting insulation materials with silicone can contribute to overall improved driving range efficiency on a single battery charge.

Momentive Silicones

Momentive silicones offer global solutions for hybrid and electric vehicles to protect the most sensitive and important components. Silicone-insulated EV charger cables are innately lightweight and contribute to manufacturers' efforts to conserve energy while decreasing environmental impacts.
 

Momentive silicone solutions are not only efficient but also provide additional benefits, such as:
 

• Thermal management and insulation (flame retardant)
• Functional safety
• Long-term protection
• Efficiency for processing

Silopren™ LSR 2600 Family

The Silopren™ LSR 2600 family possesses a lower viscosity than the Silopren™ LSR 2000 series, alongside enhanced tear resistance and reactivity. Consequently, Silopren™ LSR 2600 series can reduce the vulcanization temperature while maintaining equivalent cross-linking and without affecting the vulcanizate's physical properties.
 

LIM™ 6000 Family

The LIM™ 6000 series is a group of liquid silicone rubbers designed for high-speed injection molding. This family of silicone solutions can be molded over an expansive range of molding temperatures while retaining extraordinary release properties from metal mold trays. For example, LIM™ 6030 can be molded into EV components, including gaskets, seals, and other applications, due to its exceptional shear resistance and tensile strength.
