Ansul - Silvex Plus Foam Concentrate

Silv-Ex Plus is a versatile, low- to high-expansion foam concentrate engineered to aggressively attack Class A fuel fires including wood, paper, coal, rubber, and mixed combustibles. Its advanced surfactant formulation delivers exceptional wetting, penetration, and foam stability—even under cold weather or challenging conditions.

Key Features & Benefits

• Deep Penetration & Wetting Performance – Reduces water’s surface tension to allow solution to penetrate fuel matrices and suppress fire at its core.

• Dense, Insulating Foam Blanket – Produces a brilliant white foam that clings to surfaces, offers thermal insulation, and helps block re-ignition.

• Extended Drain Time – Maintains longer liquid retention on surfaces to maximize cooling and vapor suppression.

• Cold-Weather Tolerance – Designed to perform reliably even at lower temperatures.

• Economical Concentrate Usage – Proportioning range from 0.1 % to 1.0 % in fresh, brackish, or salt water, offering cost and storage advantages over traditional higher-rate foams.

• Environmentally Minded – Biodegradable in soils, aquatic systems, and treatment plants; contains no EPA-reportable components.

Typical Applications

• Wildland / forestry fire suppression

• Structural and interior fire support

• Deep-seated tire, coal, and rubber fires

• Use with aerial drops, fixed-wing, rotary wing, and ground-based systems
