What is AC Blowing Agent?
The scientific name of AC Blowing Agent is Azodicarbonamide. It is a light yellow powder, odorless, soluble in alkali and dimethyl sulfoxide, insoluble in alcohol, gasoline, benzene, pyridine, and water. Used in rubber and plastic chemical industry, highly flammable, incompatible with strong oxidants, strong acids, strong alkalis, and heavy metal salts. AC Blowing Agent has the characteristics of stable performance, non flammability, non pollution, non-toxic and odorless, non corrosion to molds, non dyeing of products, adjustable decomposition temperature, and no impact on curing and molding speed. This product can be foamed under normal pressure or pressure, both of which can achieve even foaming and ideal fine pore structure.
AC Blowing Agent is the blowing agent with the largest gas generation, the most superior performance, and a wide range of uses. Due to its excellent properties, it is widely used in synthetic materials such as polyvinyl chloride, polyethylene, polypropylene, polystyrene, polyamide, ABS, and various rubbers, as well as in daily life and construction products such as slippers, soles, insoles, plastic wallpapers, ceilings, floor leather, artificial leather, insulation, sound insulation materials, as well as in the molding and processing of high foaming polymer materials for PVC artificial leather, wallpapers, PE, PVC, PP cross-linked high foaming products, EPDM wind strips, and other rubber products; Flour improver, fumigant formula, can be used in greenhouses, indoor areas, septic tanks, and so on in farmland; Production agents for safety airbags, etc.

The functions of AC Blowing Agent include:
1) Reduce the density of composite materials. After the bubbles in the foaming system nucleate, as long as there is enough gas diffusing into the nucleated pores, the pores will continue to increase, thereby reducing the density of the material.
2) AC Blowing Agent reduces the sensitivity of viscosity to temperature: Due to the gas produced by AC Blowing Agent, the resistance of continuous motion is reduced, and the activation energy △ E of the fluid is reduced η， As a result, the sensitivity of viscosity to temperature decreases.
3) As the amount of AC Blowing Agent increases, it can reduce the hardness of the material and intensify thermal shrinkage.
4) AC Blowing Agent has the function of a nucleating agent, similar to throwing crushed ice into water. When a small amount of bubbles are formed, it will serve as the core to trigger the formation of bubbles of similar size.
