SEPPIC offers a range of “green” surfactants SIMULSOL??SL, combined with natural rheology modifiers SOLAGUM??AX, to manufacture green “AFFF” fire fighting foams.

SIMULSOL??SL range

Features & Benefits

Aqueous Film Forming Foam (AFFF) concentrates produce foams that extinguish hydrocarbon flammable liquids. An aqueous film is formed on the surface of the flammable liquid by the foam solution as it drains from the foam blanket.
SEPPIC APG based specialities are introduced with success either at 1%, 3% or 6% concentrates.
The SIMULSOL? range of “green” surfactants, combined with natural rheology modifiers SOLAGUM??AX, is used to manufacture these “green” AFFF concentrates for carryable fire extinghuishers and sprinkler systems or fireman equipments.

SIMULSOL??SL range

  • Bio sourced derivatives from renewable resources.
  • Rapidly biodegradable under aerobic and anaerobic conditions.
  • DID-list v2004.1: favorable Eco-toxicological profiles.
  • Low skin irritation potential as soon as blended with other surfactants (like LES-Na; Beta?nes, FAE…)
  • Actives agents in aqueous solutions at high temperature.
  • Ease to formulate AFFF and all kinds of firefigthing formulations.
  • Stabilizes rich formulations with salts.
  • Improves stock stability of manufactured products.
  • Improves dissolution of surfactants and builders.

SOLAGUM??AX, a natural rheology modifier

SOLAGUM??AX is a “green” plasticizer agent (xanthane gum coated by Senegal acacia gum). It improves film-forming properties and forms a cohesive layer to avoid restart of fire by vapors. Fully recommanded for the new generation of AFFF Concentrates when they are used to fight hydrocarbon fires.
