In the new, booming Electric vehicles (EV) market, EV battery packs are a key component. Thermal management is critical for EV battery pack safety and lifetime. For EV battery heat dissipation, thermal conductive gap filler is likely to become a key type of thermal interface material.
 
To help meet the needs of this fast-growing market, Dow developed DOWSIL™ TC-5515 LT Low Density Thermal Conductive Gap Filler, featuring light weight (density 1.95 g/cm3), good thermal conductivity (2.0 W/m·K) and reliable performance for automotive applications.
 
Low density gap filler with reliable thermal conductivity and performance for light weight EV battery pack assembly
 
A two-part RT curable 2.0 W/m·K low density Silicone Gap Filler. A soft and compressible material once cured. Specifically designed to dissipate the heat from EV battery and control unit modules to provide a reliable cooling solution due to the stability of properties during typical environmental exposure simulating the entire operating life of such a module.
 
Benefits:
Heat dissipation
Light weight and lower total cost
Good durability in automotive environment.
Easy application process and high throughput. 
UL 94 V0, Low flame risk. Meet certificate requirement
Low equipment maintenance cost due to low abrasion performance
Surface tacky once cured, easy to rework after curing and assembly
Non-flowable for thicker bondline, highly thixotropic for fast processing
Capable of accurate dispensing for automatic production
 
Limitations:
Not for thin bondlines 
No chemical bonding, tack adhesion only 
Mixing: 2-part only
 
 
Uses:
EV battery assembly
Electric control unit module assembly
Ideal for applications with large gap tolerances, typically from 150 µm to 5 mm
