Silicone Gap Filler - GF300 / GF400

Electrolube's GF300 & GF400 are two part, liquid silicone based gap fillers, which provides excellent thermal performance and can be cured at room temperature or accelerated with heat. After curing they form a low modulus elastomer preventing the 'pump-out phenomenon'. 

Thermal Performance Parameters: 

GF300 - (3.0 W/m.K)

GF400 - (4.0 W/m.K)

Key Product Features & Benefits:

  • Soft and compliant for low stress application
  • Low viscosity; easy to dispense
  • High thermal conductivite
  • Low modulus elastomer, prevents 'pump-out'
  • Supplied in two varieties - GF300 & GF400
  • Available in 50ml or 400ml

General Areas of Use:

  • Consumer electronics
  • Telecommunications – data centre servers
  • Automotive –  EV batteries and ECU’s
  • Lighting applications (including LEDs).

More Specific Areas of Use:

  • Engine and transmission control modules; effectively this controls actuators on an internal combustion engine to ensure optimal performance
  • Memory modules for PC’s and laptops
  • Power conversion equipment; semi converters and/or transformers, (converting DC to AC or a complete change of voltage). This would apply for applications such as chargers, power grid, solar panels and wind turbines).
  • MOFSET arrays with common heat sinks, for example a field effect transistor.
  • Microprocessors/graphic processors
  • Semi-conductors
