MORPEN "SOFIR" is a synthetic, biodegradable foaming agent for special purposes. It is used in fire extinguishing with the use sea and fresh (off-shore) water on ships, and other objects of the sea and river fleet. It is used for extinguishing with air-mechanical foam of low, medium and high multiplicity of combustible, solid (class A) and liquid (class B) substances, except polar liquids. MORPEN "SOFIR" is low-toxic, difficult to fire and corresponds to IV class according to GOST 12.1.007-76 - "low-hazard substances". MORPEN "SOFIR" is authorized for application by the Russian Maritime Register of Shipping using foam-generating equipment of medium multiplicity and by Russian River Register and fully meets the requirements of the International Convention for the Safety of Life at Sea (Solas-74). Storage conditions: Blowing agent is stored in closed containers - in the temperature range from -10 ° C to + 50 ° C. Guaranteed shelf life: Shelf life 36 months. The shipment is carried out by auto- and railway tanks, railway cars, containers, cars in 200 liter barrel. Characteristics: Homogeneous brown liquid without crystalline precipitate and foreign mechanical inclusions. Physicochemical characteristics: Density at 20 ° C, kg / m3: 1050 - 1200. Kinematic viscosity at 20 ° С, sq.m. * с -1: no more than 2 * 10 -1. The pour point, C: not higher, - 10. Hydrogen index (pH): 7.0 - 10.0. Concentration of the working solution in sea and fresh water, % (v / v): 4% to obtain foam of low and medium multiplicity, 6% for obtaining high-multiplicity foam. Multiplicity of foam: - Low, not less than 6. - Average, not less than 65. - High, not less than 950. Stability of foam average multiplicity, min, not less than: - The average 20. - High 10. The time for the expiration of 50% of the liquid according to IMO circ. 798 is not less than 280 seconds. Time of quenching of n-heptane (gasoline A-76) by foam of medium multiplicity from 4% solution with intensive feeding (0.032 ± 0.002) cube / dm / sq. M. * с -1, with no more than: 300.
