“In our opinion, the most important requirements to be met by heat transfer compounds for the fully automated mass production of modular battery packages are high thermal conductivity and reliable, durable stability of the gap. This means that the material must have high structural strength and adequate elasticity to compensate for the different thermal expansion of the housing materials used. It must also be possible to apply the compound reliably in order to allow a fast dispensing process at the same time as limiting wear on the metering system. Furthermore, silicone-free materials are often called for in the automotive industry. There are concerns that silicones could potentially cause serious wetting problems, especially in paint shops.
In order to alleviate these concerns and to prevent the release of siloxanes, which would impair the painting process, we have developed a number of silicone-free thermal compounds. In addition, our two-component silicone-free heat transfer products are designed for energy-saving curing processes at room temperature. In view of the quantity of material used in a process of this type, the cost is also a decisive factor for the customer. We design our materials to keep the cost to the customer reasonable at the same time as ensuring high reliability. In addition, the weight of these products must be minimized, a point we always take into consideration when selecting raw materials.”
