🔍 Leak Detection Foam – Production, Formulation and Properties
Overview:
Leak Detection Foams are specialized formulations designed to detect air, gas, and vacuum leaks in pipelines, fittings, compressors, valves, and pneumatic systems.
They are applied to a pressurized surface where leaks are instantly revealed by bubble formation, providing a quick, reliable, and non-destructive method for maintenance inspections.
These foams are widely used in HVAC systems, industrial gas lines, automotive workshops, and machinery maintenance, offering accuracy, visibility, and safety.
Modern leak detection foams are non-corrosive, non-flammable, and biodegradable, ensuring safe use on all metal and plastic surfaces.
Production and Formulation:
Leak detection foam is formulated by blending mild surfactants, foam stabilizers, corrosion inhibitors, and wetting agents in an aqueous base.
The ingredients are mixed under controlled agitation until a clear or slightly cloudy homogeneous solution is achieved.
To improve foam stability and bubble visibility, thickeners and anti-freeze agents are added.
Optional additives include fluorescent markers or dyes to enhance detection in low-light conditions.
The final product is filled into aerosol cans, trigger-spray bottles, or bulk containers, ready for direct application on suspected leak areas.
