Product Description
Sheet Foaming Regulator For Pvc Rigid Products With Higher Melt Strength And Elasticity Cas No 25852-37-3
Description:
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.
Main Features:
1. Stable foaming ratio
2. Large gas volume
3. Excellent dispersibility
4. Excellent mechanical performance of products.
Technical Index:

PROPERTIES:
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.
Applications:
Quality-Assured good dispersing in plastic and rubber blowing agent applications:
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.
