Freudenberg develops thermally conductive elastomer for EVs

Engineers at Freudenberg Sealing Technologies have developed an elastomer that merges relatively high heat capacity with electrically insulating properties by combining silicone rubber with special fillers. Electronic components can be mounted in a thermally conductive aluminum housing, which dissipates heat through cooling water or convection. Senior Application Manager Armin Striefler explains why Freudenberg decided to… Read more »

The battery that breathes—Freudenberg’s pressure compensation system

EV batteries require pressure compensation both under normal operation and during emergency ventilation. Freudenberg Sealing Technologies’ DIAvent component combines these two functions into a single design, which will be used in the ABT e-Caddy and ABT e-Transporter, two Volkswagen vans that are popular in Europe and Mexico.  To reduce battery weight and size, ABT uses… Read more »

Freudenberg launches new conductive seals for electric powertrains

Freudenberg Sealing Technologies is launching a new line of conductive seals that are designed to allow for durable connections between housings and shafts, while preventing bearing damage from electricity and electromagnetic radiation. The first functional models should be available within the next few months. Tim Leichner, Head of Strategic Product Advance Development at Freudenberg, said,… Read more »

Freudenberg introduces new testing tools for high-rpm seals in electric motors

Freudenberg Sealing Technologies has introduced several specially-designed test stands to measure frictional torque in shaft seals used in electric motors. The stands, which are located in its Weinheim test facility, can measure at rotational speeds up to 36,000 rpm. Freudenberg says that seals used between electric motors and downstream transmissions must withstand higher speeds and… Read more »

Freudenberg develops foldable and fireproof battery seals

Freudenberg Sealing Technologies has developed a seal for Li-ion batteries that not only resists fire but “folds” to offer extra protections. Here’s how it works: fixed aluminum elements are equipped with a sealing profile on their outer edges to not only provide stability but also integrate mounting points for the clips used to attach the… Read more »
