NovaTherm – Thermal Management Silicones

Silicones offer dependable battery power and increased power density for emerging EV and battery system technologies. The thermal conductivity of Novagard silicones can be altered based on each application and customer requirements up to 5.0 W/mK with standard filler packages. Higher conductivity values are possible with exotic fillers.

Tailoring Thermal Properties

We can custom tailor the uncured and cured physical properties of silicone for complex thermal interface management needs. The thermal filler package can also be modified to impart specific performance characteristics. Our polymer technology capabilities extend to adhesion promoters, which have changed the game in terms of what is possible in adhesion performance.

 

Thermal gap fillers

  • Two-part dispensable gap filler – adhesive and non-adhesive, for heat curing at the application
  • One-part moisture-cure gap filler

 

Thermal gels

  • One-part lightly-crosslinked/Cured dispensable thermal gel

 

Thermal greases and dispensable pastes

  • Heat mitigation from high performance integrated circuits on power supply PCBs
