Sealing solutions to meet the ever-changing demands ofautomotive applications
The role that thermal management plays in electric vehicles is crucial. On the one side it controls the temperature of the battery and power electronics, maximizing their working performance and therefore driving range. On the other side, it regulates the temperature in the cabin for the passenger comfort. Trelleborg has developed sealing solutions for various components within the vehicle thermal management. Our sealing experts' partner with customers to design, manufacture and supply the optimum solution to meet application needs.

Multicomponent products
Our multicomponent technology strongly bonds a range of polymers, chosen to meet your specific requirements. Unique seal geometries, combining multiple features or seals, can be customized to your application. This can improve performance, facilitate assembly and reduce part handling. The seals produced are leak-free and need less space and assembly effort, making them a cost-effective sealing solution.
Fully bonded components are available in a variety of customized combinations. Multicomponent connectors, sealing gaskets,... show the following advantages:
- Leak-free and corrosion resistant
- Easier installation and assembly
- Integrate multiple functions in a single part
- High volume output with maximum quality and consistency
- Simplified logistics by reducing handling and article management
- New design opportunities, such as more compact forms and multiple sealing positions
- Reduced Total Cost of Ownership (TCO)
Multi-way valves
Multi-way valves allow the flow regulation within the thermal management circuits, and they allow the simplification of the coolant system The valves are electronically actuated to connect different components within the circuit. Even if each manufacturer will choose their preferable connection strategy, the requirements for the internal sealing are common:
- Low friction
- High durability
- Low complexity components
Trelleborg can provide the most performant solution, adapted to your requirement custom multi-components for solution cost reduction
Seals for power electronics
The cooling of power electronics is essential for an optimum vehicle performance. Trelleborg solutions are customized to the product needs and cover either direct liquid cooling as well as indirect cooling systems. For example, the pressure-activated seals are suitable to direct liquid cooling systems. They have a particular profile design that increases safety and reliability while making the assembly steps easier.
O-Rings and molded components
The electronic components controlling the thermal management system as well as the coolant circuit connections must be perfectly sealed and protected Trelleborg offers the proper solution to every customer application, adapting the design and material to the environment needs. We provide high performance sealing capacity and durability.
