Sealing the future of mobility
The electrification of vehicles has made everyone involved in the business of mobility completely reassess their product portfolios. Throughout this revolution, Datwyler has been one step ahead with its ETEMI™ project, developing a range of elastomer, LSR and thermoplastic materials able to conduct heat and electricity, and shield electromagnetic radiation, while retaining high levels of sealing performance. These exciting new materials are ideal for a range of applications, including sealing gaskets and thermal interface materials (TIMs) for battery packs, EMI shielding seals for sensors, and anti-static seals used to discharge vehicle components.

Properties
Thin layer and low materials density supporting the lightweight aspect
High thermal conductivity
Electrical insulation
Damping properties to absorb vibrations and protect the battery cell-module-pack
(#)Anchor
Function
Supports the heat transfer from battery cells to the cooling systems to:
Keep the optimal operating temperature for long-lifetime of the battery
Prevent thermal runaway event
As the trend towards electrification continues, the ability to conduct electricity and heat, and shield components from electromagnetic signals, is increasingly important. Project ETEMI™ aims to create an entirely new category of materials designed to fulfil the highest requirements in sealing technology, delivering new capabilities in a safe and efficient manner.
