Silicone blends

Silicone requires special processing, BORFLEX® has dedicated a specific environment to "silicone" mixtures that can be mixed.

BORFLEX® has developed BORSIL, a range of silicone elastomers for use in extreme temperature and chemical conditions (fluorinated silicones).

Different families of silicones can be distinguished:

  • - Standard temperature silicones with a continuous temperature range of -50°C to +200°C which can be increased to 250°C,
  • - High-tear silicones, these are stan- dard silicones with a high tear strength,
  • - high resilience silicones with low DRC (compression set),
  • - Low-temperature silicones with a continuous temperature resistance of -110°C to +200°C,
  • - THT (very high temperature) silicones with a continuous temperature resistance of -50°C to +300°C,
  • - electrically and thermally conductive silicones,
  • "smart" silicones of the photoluminescent type (three colors available) or thermochromic type (choice of temperature and the transition color, programmable three colors and three temperatures).

BORFLEX® silicones are found in in many markets. They can meet aeronautical specifications 50, 52, 53 and 54 for silicones, and 61 and 63 for fluorinated silicones.
