Bifunctional starting compounds

Basic material properties

  • optically transparent
  • processable as a duroplastic
  • non-crystalline

Beside project based developments for various industries Fraunhofer ISC also offers scientific and technical consulting services for ORMOCER®s.

The relative proportions of the structural elements determine the material properties. The properties are controlled by the choice of base materials, by how the inorganic polycondensation reaction is conducted, and by controlling the linking reactions which lead to the construction of the organic network.

ORMOCER®s in comparison to other material classes

Influence of structural elements on various properties

  • hardness, elasticity, density, porosity
  • thermal expansion
  • polarity: hydrophilic/-phobic, oleophilic/-phobic
  • structurability
  • refractive index , dispersion
  • sensitivity (gases, ions)
  • barrier effect, corrosion protection
