Thermal runaway in batteries – requirements for insulation materials
The safety of lithium-ion batteries is a central issue in electromobility, stationary energy storage, and power electronics. A particularly critical scenario is thermal runaway in batteries – an uncontrolled chain reaction within a cell that can lead to extreme temperatures, gas evolution, and, in the worst case, fires. To minimize this risk,...
PU, EPDM or silicone foam – which sealing foam is the right one?
Selecting the right sealing and foam material is crucial for the functionality, lifespan, and cost-effectiveness of technical applications. PU foam, EPDM foam, and silicone foam are among the most frequently used materials – but they differ significantly in their properties and applications. This article provides practical decision-making support for design, purchasing, and development. Material overview: Three...
Batteries as large-scale storage – a key technology for stabilizing power grids
The expansion of renewable energies presents new challenges for electricity grids worldwide. Wind and solar power do not supply electricity continuously, but rather depending on weather conditions and time of day. To compensate for these fluctuations and smooth grid load, batteries are becoming increasingly important as large-scale storage solutions. Large battery storage systems can absorb excess electricity and feed it back into the grid when needed...

DIN EN 45545-2 – Fire protection requirements for materials in railway vehicle construction
Harmonised Fire Protection Standards for Europe: With the introduction of DIN EN 45545, a harmonised fire protection concept for rail vehicles was created across Europe. This standard replaces previous national regulations such as DIN 5510, BS 6853, and NF F 16-101. Since 2016, all newly built rail vehicles within the EU must comply with the requirements of EN 45545. Part 2 of the standard...
Thermal management in lithium-ion batteries: Materials as a key technology
Why thermal management is crucial for battery systems: Modern lithium-ion batteries operate within a sensitive temperature range. Even slight deviations from the optimal operating temperature can significantly impact performance, lifespan, and safety. Particularly in applications such as electric vehicles, stationary storage systems, and fast-charging infrastructure, considerable thermal stresses occur during charging and discharging processes. Temperature spikes ("hotspots") in individual cells lead to uneven aging...
Laminated materials according to DIN EN 45545-2
Fire-resistant laminate materials for railway vehicle construction. Modern railway vehicle construction places particularly high demands on preventive fire protection. Materials used in interiors and technical assemblies must not only be mechanically robust and electrically insulating, but also meet stringent requirements regarding flammability, smoke development, and toxicity. The relevant standard for this is DIN EN 45545-2, which...
Elastomers according to EN 45545-2 – Safety and performance for railway vehicle construction
Preventive fire protection plays a central role in modern railway vehicle construction. Elastomers, in particular, which are widely used as sealing, insulating, damping, and protective materials, must meet the highest requirements for flame retardancy, smoke emission, and toxicity. The European standard EN 45545-2 is the relevant standard in this regard. Dr. Dietrich Müller GmbH offers a wide range of...
