Product Introduction
The appearance of AC/ADC foaming agent (Azodicarbonamide ADC) is yellow to light yellow powder. The finer the particles, the lighter the color. The specific gravity (water = 1) is 1.65, which is flammable but does not support combustion. It is the most economical and widely used organic chemical foaming agent in industrial applications. It is an exothermic foaming agent. Haihong blowing agent AC/ADC has good dispersion, stable gas volume, and the residue after decomposition is non-toxic, odorless and pollution-free. Mainly used to produce closed-cell rubber and plastic foam products. Ordinary ADC decomposes at a temperature of 200~220°C. In order to meet the requirements of rubber and plastic processing, the decomposition temperature is usually adjusted by adding special additives.
