Major Characteristics


  • Elastosil vulcanises by addition reaction and is made of two components A and B, with a mix ratio of 9:1 or 10:1 depending on the product. The catalysing agent is contained in Component B.
  • This proportion makes mixing simple.
  • A special characteristic of addition reaction silicone is the absence of contraction during vulcanisation.
  • To avoid possible vulcanisation inhibition, the work materials must be perfectly clean during the vulcanisation process.
  • The moulds can be used immediately after de-moulding.
  • The addition-based silicone reticulation process time can be shortened by increasing the temperature.
  • Shore A hardness range 13 to 55.
