Adding a gasket to seal a device, whether it is keeping out dust, air, water, or something else, seems like it would be an easy part of design.  However, there are a multitude of material options available for most applications.  Choosing the right one may require some research.  This is why we are starting a blog series outlining the features and benefits associated with the many foams that fit into this large subset of gasket material options:  Foams for Low Clamping Force Seals

We are starting this series with SILICONE FOAM

  • Maintains its flexibility across a wide temperature range (-50ºC to 200ºC)
  • Superior flame resistance; low flame, smoke and toxicity upon combustion
  • Resists environmental extremes like UV and ozone
  • Resilient to mechanical fatigue
  • Superior resistance to compression set and creep
