  • the fluid reservoir can be advantageously incorporated easily into various matrices, even into liquid matrices, without there being any significant disadvantageous interaction with the matrix.
  • substantially undecomposed takes into account the fact that some materials or compounds or substances may degrade upon the supply of thermal energy. This means that the material in question is changed in such a case by the influence of temperature in its structure that it is thereby converted into a no longer suitable for its original purpose.
