ADC Blowing Agent
Property
:
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.
Application
:
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. 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 and corporate standard. The product is certified by “Quality Management System” and the national “Measurement Management System”.

Packing, transportation and storage
:
It can be packed in carton or compound paper bag. Special packing is negotiable separately.
Safety:
This product itself is nontoxic but may release a great deal of N2 and CO when decomposed at a temperature above 120 ℃. Poor ventilation could result in toxicosis.
