AC BLOWING AGENT SPECIFICATION
Name: Azodicarbonamide
Molecular Formula: C2H4N4O2
This product mainly falls into three categories according to average grain size Dn, decomposition temperature T, and the DnxTy series compounded by average grain size Dn and decomposition temperature T. It follows the standard Q/321100 ZH008-2004.
Property
Yellow powder, specific gravity of 1.65, nontoxic, stink-free, flammable, capable to generate tremendous froth. During decomposition, 32% weight decomposed into gas, 27% sublimed 41% residues. Among the decomposed gas, 65% is N2, 32% CO and 3% CO2. Decomposition heat: 359.5J/g; Specific heat: 0.26; combustion heat: 1070kJ/mol.
Applications
It is one of blowing agents that are widely applied. 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. It enables the frothed products to have an outstanding property; especially it is favorable for increasing the extensibility of goods and obtaining more outstanding aperture structure.
Quality Standard
It is produced in strict accordance with the chemical industrial standard HG/T 2097-1991 and the corporate standard Q/321100 ZH008-2004.
