Jiangsu Suolong (江苏索龙消防科技) manufactures low, medium and high expansion firefighting foam concentrates — AFFF, alcohol-resistant AFFF, fluoroprotein and protein — at Xinghua in Taizhou, from a business whose history runs back to 1967. Four of its low-expansion concentrates are certified under BSI Kitemark licence KM 688132 against BS EN 1568-3:2018 and BS EN 615: SFE-AFFF 3% and SFE-AFFF 6% at performance grade IB, SFE-AFFF/AR 3-3% at grade IB and SFE-FP 3% at grade IIA, all approved for use with seawater. A directly checkable Kitemark listing is unusual for a Chinese foam producer.
