Ceramifying Silicone for EV Battery Safety
Keywords: ceramifying silicone, EV battery thermal barrier, flame retardant silicone, battery sealing silicone
Key sentence: Advanced ceramifying silicone forms rigid heat-blocking ceramic layers above 600°C to slow thermal runaway inside electric vehicle battery packs.
Wacker updates its ELASTOSIL® CM ceramifying silicone series for EV battery safety systems. When exposed to extreme high heat, the silicone converts into a dense ceramic shield, blocking radiant heat and hot particle splash from faulty cells. Independent lab tests show the coating can lower 1300°C flame radiation to below 150°C, extending escape windows for EV passenger safety. This silicone works well on flexible fabric substrates and battery housing coatings, matching the booming demand for fire-resistant battery sealing and thermal insulation materials. Auto Tier 1 suppliers are switching from traditional ceramic sheets to coated silicone barriers for lighter weight and easier forming. It becomes a preferred high-performance silicone solution for new energy battery pack designers across Europe, Southeast Asia and North America.
