Why Silicone for Battery Applications?

Thermal Stability

  • High temperature resistance
  • Wide temperature range retention of elastomeric properties

Tunable: Modulus/Hardness/Cure chemistries

  • Hardness range from hard to soft depending on application
  • Flexible/compliant, retains flexibility at high filler (thermal, electrical) content with high elongation at break
  • Fast RT cure for large component fixing and increased productivity

Thermal management performance

  • Wide thermal conductivity range available
  • Silicone provides low thermal resistivity

Thermal event isolation

  • Slow the spread of thermal events in lithium ion battery

Light weighting

  • Silicone foams meet UL requirements with low weight

Advancing your Battery Pack Assembly

Portfolio of Advanced Thermally Conductive Materials: Focus on Gap Fillers


Battery Pack Assembly


Introducing: thermal runaway propagation prevention

  • Silicones can slow the spread of thermal events in lithium ion battery applications
  • Filled or unfilled silicones available:                       
    • Gap fillers
    • Foams
    • Encapsulants
    • Gels
  • Application requirements determine material selection


  • Silicone foams can be a light weight alternative to traditional encapsulant and sealant options.
  • Foam encapsulant can provide cell protection in the case of a thermal event.


Silicone Foam flammability testing

Battery Pack Assembly


Introducing: EMI Shielding

Increasing density of electronic components in many market segments.

Shielding prevents cross-talk of electronic circuits, detectors, RF signals.

Silicones provide flexibility over a wide range of temperature and environmental conditions

Conformal Coatings

Key Benefits

  • Improves reliability in humid environments. 
  • Protects PCBs and other electronic components against environmental particles, moisture and contaminants, preventing sort circuits nd corrosion of conductors and solder joints
  • Protects circuits and components from abrasion and solvents
  • Stress relieving
  • Protects insulation resistance
  • Reduces conductor spacing on PCBs
  • Good dielectric properties (insulation, moisture resistance, breakdown voltage)
