volatile liquids such as oil, gasoline, or chemical solvents.<\/p>\n<p>Unlike water, which cannot smother or blanket fuel surfaces, foam forms a stable foam layer that seals off flammable vapors from oxygen in the air, while simultaneously cooling the burning surface and preventing re-ignition.<\/p>\n<p>For oil and chemical tankers, where a wide range of fuels and solvents are stored, foam concentrate systems play a critical role in liquid fire control. When activated, the system mixes the foam concentrate with water at a specified ratio (typically 3% or 6%) to produce a uniform, stable foam blanket that spreads over the burning surface, effectively suppressing the fire.<\/p>\n<p><img decoding=\"async\" loading=\"lazy\" class=\"alignnone wp-image-19210 size-full\" src=\"https:\/\/marico.com.vn\/wp-content\/uploads\/2025\/10\/Chat-tao-bot-chua-chay-tren-tau.jpg\" alt=\"Firefighting foam on board\" width=\"1200\" height=\"675\" srcset=\"https:\/\/marico.com.vn\/wp-content\/uploads\/2025\/10\/Chat-tao-bot-chua-chay-tren-tau.jpg 1200w, https:\/\/marico.com.vn\/wp-content\/uploads\/2025\/10\/Chat-tao-bot-chua-chay-tren-tau-300x169.jpg 300w, https:\/\/marico.com.vn\/wp-content\/uploads\/2025\/10\/Chat-tao-bot-chua-chay-tren-tau-1024x576.jpg 1024w, https:\/\/marico.com.vn\/wp-content\/uploads\/2025\/10\/Chat-tao-bot-chua-chay-tren-tau-768x432.jpg 768w, https:\/\/marico.com.vn\/wp-content\/uploads\/2025\/10\/Chat-tao-bot-chua-chay-tren-tau-600x338.jpg 600w\" sizes=\"(max-width: 1200px) 100vw, 1200px\" \/><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Common_types_of_Firefighting_Foam_Concentrates\"><\/span>Common types of Firefighting Foam Concentrates<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<div>\n<table style=\"height: 409px; width: 100%; border-collapse: collapse; border-color: #000000; border-style: solid;\" border=\"1\">\n<colgroup>\n<col \/>\n<col \/>\n<col \/><\/colgroup>\n<tbody>\n<tr style=\"height: 49px;\">\n<td style=\"height: 49px; text-align: center; width: 18.0361%;\"><strong>Foam Type<\/strong><\/td>\n<td style=\"height: 49px; text-align: center; width: 40.2806%;\"><strong>Main Composition<\/strong><\/td>\n<td style=\"height: 49px; text-align: center; width: 41.6834%;\"><strong>Typical Application<\/strong><\/td>\n<\/tr>\n<tr style=\"height: 72px;\">\n<td style=\"height: 72px; width: 18.0361%;\">Protein Foam<\/td>\n<td style=\"height: 72px; width: 40.2806%;\">Based on naturally hydrolyzed protein with foam stabilizing additives.<\/td>\n<td style=\"height: 72px; width: 41.6834%;\">Used for non-polar fuel fires (e.g., diesel, heavy oil) where rapid extinguishment is not critical but long-term stability is required.<\/td>\n<\/tr>\n<tr style=\"height: 72px;\">\n<td style=\"height: 72px; width: 18.0361%;\">Fluoroprotein Foam (FP)<\/td>\n<td style=\"height: 72px; width: 40.2806%;\">Modified protein foam containing fluorocarbon surfactants.<\/td>\n<td style=\"height: 72px; width: 41.6834%;\">Applied where continuous blanket formation and greater burn-back resistance are needed compared to standard protein foam.<\/td>\n<\/tr>\n<tr style=\"height: 72px;\">\n<td style=\"height: 72px; width: 18.0361%;\">Aqueous Film Forming Foam (AFFF)<\/td>\n<td style=\"height: 72px; width: 40.2806%;\">Synthetic foam made with foaming agents and fluorochemical surfactants, capable of forming an aqueous film over hydrocarbon fuels.<\/td>\n<td style=\"height: 72px; width: 41.6834%;\">Effective for non-polar hydrocarbon fires (e.g., gasoline, light oil) typically found on oil tankers.<\/td>\n<\/tr>\n<tr style=\"height: 72px;\">\n<td style=\"height: 72px; width: 18.0361%;\">Alcohol-Resistant AFFF (AR-AFFF)<\/td>\n<td style=\"height: 72px; width: 40.2806%;\">AFFF enhanced with polymer or additive layers to resist polar solvents (alcohols).<\/td>\n<td style=\"height: 72px; width: 41.6834%;\">Designed for chemical tankers or areas containing polar solvent cargoes and gasoline\/oxygenate blends.<\/td>\n<\/tr>\n<tr style=\"height: 72px;\">\n<td style=\"height: 72px; width: 18.0361%;\">Fluorine-Free Foam (FFF \/ F3 \/ SFFF \/ NFF)<\/td>\n<td style=\"height: 72px; width: 40.2806%;\">Formulated without PFAS or fluorocarbon surfactants.<\/td>\n<td style=\"height: 72px; width: 41.6834%;\">Used where environmental protection or fluorine-free compliance is required; may be accepted for use on ships if type-approved.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<p>Each foam type offers specific performance characteristics depending on the fuel involved and the operating environment.
