        AC Blowing Agent


        CAS No.: 123-77-3
        Molecular formula: C2H4N4O2
        Packing: 25kg/Paper bag; 20MT can be loaded into1x20’FCL
        Properties:
        Yellow powder, specific gravity of 1.66, nontoxic, stink-free, flammable, capable to generate tremendous froth. During decomposition, 32% weight decomposed into gas, 27% sublimed, 41% residues. Among the decomposed gases, 65% is N2, 32% CO and 3% CO2. Decomposition heat: 359.5 J/g; specific heat: 0.26; combustion heat: 1070 KJ/mol.
        Applications:
        It is one of the most widely applied blowing agents. Frothing can be performed at normal pressure or increased pressure. It is widely used for frothing EVA, PE, natural rubber and PVC+NBR mixture etc., especially for large-mould hot press frothing and small-mould hot press frothing of EVAMD shoes material.
