As the trend towards electrification continues to gather momentum, the ability to conduct electricity and heat, as well as to shield certain components from electromagnetic signals, is increasingly important. Project ETEMI™ is the driving force behind the creation of an entirely new category of materials – those designed to fulfil the highest requirements in terms of sealing technology, in addition to delivering the aforementioned capabilities in a safe and efficient manner.Luana Lettieri, Manager Material Development
Ultimately, ETEMI™ will be the catalyst for the creation of a material matrix whereby electrical and thermal conductivity and EMI shielding can be coupled and decoupled to suit a wide variety of applications. The thermal management of an electric vehicle battery could be managed in part by its sealing material, for example, while EMI shielding could likewise be introduced via sealing technology to safeguard components such as sensors and critical control units from environmental effects as well as electromagnetic interference.
Electrical conductivity for discharging and antistatic materials is also possible via sealing technology, and there are many examples of this combined functionality enabling certain components to be removed – such as metal conductors – thus delivering weight reduction benefits. Overall, the key objective is to balance the ability to provide a high-performance seal with the need to meet the many additional requirements arising from electrification.
