azodicarbonamide blowing agent manufactur ers in india
ADCA (CAS: 123-77-3, NH2CON = NCONH2) is an odourless crystalline orange substance. The main component content is 95% . The decomposition temperature was 210 ° C and the number of gases was 218 cm3/g. When heated, ADCA releases molecular nitrogen (mainly) and a small amount of ammonia. The optimum decomposition...
azodicarbonamide production azodicarbonamide subway
Polymer foams are mainly products with good performance balance, light weight, low density, outstanding strength/weight ratio, excellent insulation and Energy Absorption. Especially in packaging, biomedicine, architecture, automobile, carpet liner, textile, furniture, sole and toy production, it has a broad...
azodicarbonamide chemical blowing agent
Comparison of the degree of decomposition of different initiators under isothermal conditions shows that Zinc stearate is the most active initiator. It is determined that there is an optimum decomposition curve of azodicarbonamide-Zinc stearate in the temperature range of 130 ~ 1500 °C. Characteristics 1. Gas...
The process of plastic Sol foaming has been extensively studied and is now well understood. Foaming can be achieved by the use of chemical blowing agents, which can be decomposed at optimum temperatures with high gas yields, that is, high enough to cause polymer to deform easily, however, low gas production is...
azodicarbonamide negative effects
Azodicarbonamide has been widely used as a blowing agent for expanded Vinyl Foams for many years. Foaming agents are particularly useful in chemically embossed floors because they are sensitive to factors that affect their decomposition temperature, allowing the expansion of the foam to be controlled. Characteristics...
The maximum decomposition rate of ADCA initiator mixture depends on temperature, type and amount of initiator. The mixed decomposition rate of ADCA-initiator depends on the temperature, the nature of the initiator and the amount of the initiator. With the increase of temperature (130 ~ 150 °C) , the mixed...
manufacturing process of azodicarbonamide
Some researchers believe that the interaction of Adca with calcium or zinc salts produces corresponding azo dicarboxylate salts as initiators for thermal decomposition. In addition, the activation mechanism of ADCA decomposition is Lewis acid-base interaction, in which the active additive metal acts as Lewis acid,...
what does azodicarbonamide mean
ADC is a yellow or light yellow powder crystal. Its color depends on its granularity. Its specific gravity is 1.65. Decomposition temperature is 205-215 ° c (visual measurement of melting point tube) . It's nontoxic and odorless. It has good storage stability. Self-extinguishing in case of fire, not burning. Of all...
