This product mainly falls into three categories according to average grain size Dn, decomposition temperature.
Property
Yellow powder, specific gravity of 1.*5, nontoxic, stink-free,
flammable, capable to generate? tremendous froth. During
decomposition, *2% weight decomposed into gas, *7% sublimed, *1%
residues. Among the decomposed gas, *5% is N2, *2% CO and 3% CO2.
Decomposition heat: **9.5J/g; specific heat: 0.*6; combustion
heat:***0kJ/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.
