Azodicarbonamide 123-77-3 made in China:
AC blowing agent azodicarbonamide
Azodicarbonamide is widely used in the plastic industry,particularly in the production of PVC plastisol foams,as a foaming agent added to increase the porosity of plastics.ADCA is used in food and photo industry as a bleaching agent.
Besides,it has the application in electronics for forming ribbed battery separators.

Decomposition Temperature( °C )
1,1′-azobisformamide (azodicarbonamide, ADCA) exists at ambient temperatures as a yellow to orange red crystalline powder. It is slightly soluble in water. Highly flammable. Incompatible with strong oxidizing agents, strong acids, strong bases, heavy metal salts. ADCA is an efficient exothermic foaming agent generating mostly nitrogen and carbone dioxide gas. ADCA is an electron acceptor so act as an oxidizing agents.
The decomposing temperature for hightemperature foaming agents is over 200°C, the gas volume reaches 220ml/g (under the standard temperature and pressure, called STP). Decomposition gases mainly including N2 and CO2 accompanied with a small amount of CO and NH3.
Artificial Leather AC Chemical Processing Azodicarbonamide The decomposing temperature can be adjustable within 150-200°C after adding an adequate amount of decomposing activator ( foam promoting agent),
common activators including Zinc, Barium oxides and salts of Zinc and Barium, stearates and stearate salts.
The thermal decomposition of azodicarbonamide results in the evolution of nitrogen, carbon monoxide, carbon dioxide, and ammonia gases, which are trapped in the polymer as bubbles to form a foamed article. This is widely used in production of PVC, PP, LDPE, EVA and other plastic foaming articles like window and door gaskets, padded floor mats, gym/exercise mats or shoe soles.
ADCA can be pure or modified and modification affects the reaction temperatures.
FORMING RIBBED BATTERY SEPARATORS
Ribs are formed on a nonwoven mat to produce a battery separator. The ribs are formed by extruding a foamed polymer onto the nonwoven mat by extruding the foamed polymer through a multi-hole die as the nonwoven mat follows an arc passing over a mat backup plate. After the ribs have been extruded and the foamed polymer is still soft, the nonwoven mat with the extruded ribs may be passed through a fixed gap such as a pair of calender rolls to produce a battery separator of uniform thickness.
Storage stability is excellent under normal conditions. This PVC Blowing Agent should be stored in a cool dry place, away from fire, spark and heat. If fire, extinguishing use water spray, carbon dioxide or dry chemical powder. Don't attempt manual fire fighting.
