Blowing Agent H scientific name two of five methyl-4-nitroso-amine, no smell, but the smell of formaldehyde under wet conditions. Soluble in dimethylformamide and dimethyl sulfoxide, the decomposition of gas is mainly N2, also contains a small amount of NO, CO2, O2, water and formaldehyde.
H is widely used in rubber foam blowing agents, such as: natural rubber, styrene-butadiene rubber, nitrile rubber, do not change color, non-polluting. In addition, the blowing agent H in the plasticized PVC lamination, blow molding foam also has wider application. Foam is usually to add some additives, such as: the surface treated urea, biuret, salicylic acid, phthalic acid, polyols, etc., to reduce the decomposition temperature of blowing agent H, so that in the 120-190 ° C range of the production of gas. H blowing agent decomposition will release a large number of heat, when the need for thick products carefully.
H blowing agent be placed in ventilated, dry place, away from heat and fire, avoid direct sunlight, avoid contact with acidic substances. Processing establishments should be well ventilated to avoid inhalation of dust and prolonged contact with skin. Burning releases large amounts of heat, fire extinguishing large amount of water use is prohibited by hand fire.
