Materials

Generally all Boettcher compounds are available for application in digital printing. Specially developed compounds for the use in digital printing are for example:

  • Polyurethanes (defined electrically conductive or for heavy duty applications)
  • EPDM (non blooming, electrically conductive)
  • ECO (defined electrically conductive)
  • NBR (electrically conductive)
  • Polyimide (high temperature resistant and/or defined electrically conductive)
  • Hardness range: 10 ShoreA up to 90 ShoreD
  • Specific resistance: 103-1015 Ωcm; 106 - 1010 Ωcm defined specific resistivity

All given data are typical values and depend on roller type.

Production process

  • mould casting
  • rotational casting
  • spray coating
  • dip coating
