Ceramic silicone tape from ANDI is a high-performance ceramifiable fire-resistant adhesive tape,designed to address thermal runaway risks within new energy vehicle power battery PACK.It combines the flexibility of silicone substrate with ceramifiable functional fillers,serving as a passive thermal barrier material for automotive battery safety design.

 

　　ANDI Material Characteristics

 

　　Ceramization performance:Flexible under normal operating temperature;when exposed to intense heat or flame during thermal runaway,it rapidly converts into a hard,compact ceramic protective layer.No molten dripping occurs during combustion to avoid secondary ignition.

 

　　Flame&heat resistance:Achieves UL94 V‑0/FV‑0 flame retardant rating.The ceramic layer can resist high temperature above 1300°C,blocking flame jet and heat radiation.

 

　　Electrical insulation:Stable dielectric property at room and elevated temperature.High breakdown voltage,effectively preventing creepage and high-voltage short circuit of live components.

 

　　Environmental reliability:Halogen-free and RoHS compliant.Passed double 85 aging,thermal cycling and mechanical vibration tests,maintaining stable adhesion and integrity under long-term vehicle working conditions.

 

　　Processing advantage:Good conformability to curved and irregular component surfaces.Easy manual wrapping and suitable for automatic tape winding in mass production lines.

 

　　Main Application Scenarios in NEV Battery PACK

 

　　1.High-voltage busbar insulation&fire protection

 

　　As the primary application,ANDI ceramic silicone tape is wrapped around PACK internal high-voltage copper busbars and connecting terminals.In daily operation,it protects conductors from friction and insulation failure caused by vehicle vibration.When a single cell triggers thermal runaway,the ceramic layer instantly forms to isolate high-temperature flame and hot gas,preventing short circuit of high-voltage circuits and suppressing the spread of thermal failure.

 

　　2.Module partition thermal barrier

 

　　Attached to module separator surfaces to build local fire isolation zones between cells and modules.It slows heat transfer from faulty cells to neighboring cells,delaying cascading thermal runaway.The tape can also assist in fixing aerogel thermal insulation pads,integrating insulation and flame resistance in one material.

 

　　3.High-voltage wire harness protection

 

　　Used for wrapping high-voltage cables inside the battery pack.It avoids insulation abrasion during vehicle vibration.In thermal emergency,it restrains flame spread along wiring harness and reduces the risk of fire diffusion inside PACK.

 

　　4.Insulation reinforcement on metal structural components

 

　　Applied to module end plates,metal brackets and PACK casing contact areas.It increases creepage distance between metal structure and energized parts,lowering leakage and short-circuit hazards.

 

　　Case Benefits

 

　　This NEV PACK project adopts ANDI ceramic silicone tape as lightweight passive fire protection solution.Compared with rigid fire insulation materials,its flexible silicone base can closely fit complex structural contours without cracking or peeling under vibration.It saves installation space and reduces overall PACK weight.

 

　　In thermal runaway events,the generated ceramic barrier cuts off flame and heat conduction,prolonging thermal propagation time and providing precious escape and warning time.The material helps the battery pack meet automotive safety standards,balancing safety performance,assembly efficiency and manufacturing cost.
