  • Wavelength Dependency on Refractive Index
    “Phenyl type silicones have a higher refractive index than Dimethyl type silicones’’
  • Transparency of Silicones
    “Both Phenyl and Dimethyl type silicones have transmittance rates above 92% above the visible range”
  • High Thermal Stability of Silicones
    “Silicones show a much higher thermal stability than epoxies”
  • Thermal Ageing of Dimethyl vs Phenyl-type
    • At higher temperatures (>170°C), Dimethyl-type silicones show significant transmittance loss.
    “Both Phenyl and Dimethyl type silicones have transmittance rates above 92% above the visible range”
    • At higher temperatures (>170°C), Phenyl-type silicones show little transmittance loss.
  • No Color Change of Silicones
    Silicone (Siloxane Structure)
    Organic Resin (PPA, Epoxy, etc)
    Decomposition generates
    Decomposition generates
    CO2, CO (gas)+C (Carbon Black)
    +NH (Brownish) + … = Color Change
    SiO2 (glass)+CH4 (gas)
    + …= NO Color Change
