Product Introduction

ADC foaming agent appearance for yellow to light yellow powder, the finer particle , the lighter color . Specific gravity(water=1) is 1.65, flammable but don't support combustion. It is the most economic and widely used organic chemical foaming agent in industrial applications. It is a exothermic foaming agent. Haihong ADC foaming agents have good dispersion and stable gas volume, the residue after decomposition is non-toxic, odorless and non-polluted. Mainly used in production of closed cell rubber & plastic foaming products. Ordinary ADC decomposes at the temperatures of 200 ~ 220℃, to meet the requirements of Rubber and Plastics processing, usually the decomposition temperature is adjusted by adding special additives.
