It does not contain any halogenated organic compounds. Both the foam concentrate and foam solution are readily biodegradable and environmentally friendly.<\/p>\n<p data-start=\"1057\" data-end=\"1289\">SELVA 3 forms a foam blanket that separates oxygen from the fuel or fire zone, thereby effectively extinguishing fires. Its firefighting performance is comparable to fluorinated foam concentrates when used on hydrocarbon fuel fires.<\/p>\n<p data-start=\"1291\" data-end=\"1378\">SELVA 3 can be used as a replacement for AFFF (Aqueous Film Forming Foam) concentrates.<\/p>\n<p data-start=\"1380\" data-end=\"1528\">SELVA 3 is suitable for use with fresh water to extinguish Class B fires (hydrocarbon fuels). It is not suitable for fires involving polar solvents.<\/p>\n<p data-start=\"1530\" data-end=\"1613\">SELVA 3 can also be used for Class A fires due to its excellent wetting properties.<\/p>\n<p data-start=\"1615\" data-end=\"1888\">SELVA 3 can be applied using low-, medium-, and high-expansion foam discharge equipment (such as nozzles, monitors, foam chambers, etc.). However, since it does not form an aqueous film, its performance with spray nozzles is not as effective as AFFF-type foam concentrates.<\/p>\n<h3 data-start=\"1615\" data-end=\"1888\"><span class=\"ez-toc-section\" id=\"Technical_Specifications\"><\/span><strong>Technical Specifications<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<table style=\"width: 100%; height: 432px;\">\n<thead>\n<tr style=\"height: 24px;\">\n<th style=\"height: 24px;\"><strong>No.<\/strong><\/th>\n<th style=\"height: 24px;\"><strong>CATEGORY<\/strong><\/th>\n<th style=\"height: 24px;\"><strong>PROPERTY<\/strong><\/th>\n<th style=\"height: 24px;\"><strong>VALUE<\/strong><\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr style=\"height: 48px;\">\n<td style=\"height: 48px;\">1<\/td>\n<td style=\"height: 48px;\"><strong>APPLICATION RATE<\/strong><\/td>\n<td style=\"height: 48px;\">Recommended use of SELVA 3 concentrate<\/td>\n<td style=\"height: 48px;\"><\/td>\n<\/tr>\n<tr style=\"height: 24px;\">\n<td style=\"height: 24px;\"><\/td>\n<td style=\"height: 24px;\"><\/td>\n<td style=\"height: 24px;\">\u2022 Class A fires<\/td>\n<td style=\"height: 24px;\">3%<\/td>\n<\/tr>\n<tr style=\"height: 24px;\">\n<td style=\"height: 24px;\"><\/td>\n<td style=\"height: 24px;\"><\/td>\n<td style=\"height: 24px;\">\u2022 Hydrocarbon fires<\/td>\n<td style=\"height: 24px;\">3%<\/td>\n<\/tr>\n<tr style=\"height: 48px;\">\n<td style=\"height: 48px;\">2<\/td>\n<td style=\"height: 48px;\"><strong>PHYSICAL PROPERTIES OF CONCENTRATE<\/strong><\/td>\n<td style=\"height: 48px;\">Appearance \/ Color<\/td>\n<td style=\"height: 48px;\">Clear liquid, yellow<\/td>\n<\/tr>\n<tr style=\"height: 24px;\">\n<td style=\"height: 24px;\"><\/td>\n<td style=\"height: 24px;\"><\/td>\n<td style=\"height: 24px;\">Density at 20\u00b0C<\/td>\n<td style=\"height: 24px;\">1.017 \u00b1 0.01<\/td>\n<\/tr>\n<tr style=\"height: 24px;\">\n<td style=\"height: 24px;\"><\/td>\n<td style=\"height: 24px;\"><\/td>\n<td style=\"height: 24px;\">pH at 20\u00b0C<\/td>\n<td style=\"height: 24px;\">8.0 \u00b1 1.0<\/td>\n<\/tr>\n<tr style=\"height: 48px;\">\n<td style=\"height: 48px;\"><\/td>\n<td style=\"height: 48px;\"><\/td>\n<td style=\"height: 48px;\">Viscosity at 20\u00b0C, 375 s\u207b\u00b9 (Brookfield)<\/td>\n<td style=\"height: 48px;\">&lt; 5 mPa\u00b7s<\/td>\n<\/tr>\n<tr style=\"height: 24px;\">\n<td style=\"height: 24px;\"><\/td>\n<td style=\"height: 24px;\"><\/td>\n<td style=\"height: 24px;\">Freezing point<\/td>\n<td style=\"height: 24px;\">\u2264 \u20134\u00b0C<\/td>\n<\/tr>\n<tr style=\"height: 48px;\">\n<td style=\"height: 48px;\">3<\/td>\n<td style=\"height: 48px;\"><strong>FOAM SOLUTION PROPERTIES<\/strong><\/td>\n<td style=\"height: 48px;\">Surface tension at 20\u00b0C<\/td>\n<td style=\"height: 48px;\">\u2264 30 mN\/m<\/td>\n<\/tr>\n<tr style=\"height: 48px;\">\n<td style=\"height: 48px;\"><\/td>\n<td style=\"height: 48px;\"><\/td>\n<td style=\"height: 48px;\">Interfacial tension (with Cyclohexane)<\/td>\n<td style=\"height: 48px;\">4.0 \u00b1 1.0 mN\/m<\/td>\n<\/tr>\n<tr style=\"height: 24px;\">\n<td style=\"height: 24px;\"><\/td>\n<td style=\"height: 24px;\"><\/td>\n<td style=\"height: 24px;\">Low expansion ratio<\/td>\n<td style=\"height: 24px;\">\u2265 7<\/td>\n<\/tr>\n<tr style=\"height: 24px;\">\n<td style=\"height: 24px;\"><\/td>\n<td style=\"height: 24px;\"><\/td>\n<td style=\"height: 24px;\">25% drainage time<\/td>\n<td style=\"height: 24px;\">\u2265 8 minutes<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<table style=\"width: 100%; height: 480px;\">\n<tbody>\n<tr style=\"height: 72px;\">\n<td style=\"width: 5.87248%; height: 72px;\">4<\/td>\n<td style=\"width: 37.7516%; height: 72px;\"><strong>STANDARDS AND CERTIFICATION<\/strong><\/td>\n<td style=\"width: 54.698%; height: 72px;\">SELVA 3 has been tested and certified in accordance with the following standard: <strong>TCVN 7278:2003<\/strong>.<\/td>\n<\/tr>\n<tr style=\"height: 168px;\">\n<td style=\"width: 5.87248%; height: 168px;\">5<\/td>\n<td style=\"width: 37.7516%; height: 168px;\"><strong>COMPATIBILITY WITH STORAGE MATERIALS<\/strong><\/td>\n<td style=\"width: 54.698%; height: 168px;\">SELVA 3 is compatible with standard carbon steel and materials made from stainless steel (SUS 304 and SUS 316) or copper alloys.
