Dafo Fomtec AB

Renex BC Standard is a multi purpose dry chemical powder with a good efficiency in fires of Class B, C and E.  Renex BC STANDARD Is based on highly efficient Calium Carbonate/Sodium Bicarbonate and made resistant to influence of climatic extremes by means of hydrophobic agents.

Extinguishing Mechanism

Potassium Sulphate powders extinguish flammable liquid fires by interfering with the chemical reactions which are taking place in the combustion zone. These chemical reactions produce “free radicals” which attach themselves to the surface of the powder particles introduced into the flame, thus the flame ceases to exist and the fire is extinguished.

The grinding of the base material to obtain a suitable surface area and particle size distribution is critical to the reaction of the particle surface.


Our powders are available in various packaging sizes and styles. For bulk filling, they can be supplied in 25 kilo multiwall paper sacks, stretch wrapped on pallets of 1000 kilo. These packages are suitable for containerised shipments.

Powders can also be supplied in 1000 kilo big-bags to simplify handling and to freed into extinguisher filling machine hoppers. This packaging is also suitable for containerised shipments.


Our powders are formulated not to be affected by long term storage However, although all powders are stable at low temperatures, there are upper temperature limits for storage witch will depend on the chemical nature of the particular powder.
