  • The concentrated solution is then congealed and subsequently dried according to the various product specifications
  • The paraformaldehyde that is produced is made up of white, free flowing granules or prills with a Formaldehyde content of 91 – 98 % w/w with the ideal being 95 ± 1 % w/w
  • Key features of the product are:
    • high reactivity
    • excellent solubility
    • very good storage properties
