Product Overview
AC Foaming Agent, also known as Azodicarbonamide (ADA), is the most widely used chemical blowing agent in the plastics and rubber industry. It is a yellow-orange crystalline powder that decomposes at high temperatures (200–220°C) to release gases such as nitrogen, carbon monoxide, carbon dioxide, and ammonia.
These gases form bubbles inside molten polymers, creating lightweight foamed products with superior properties and significant material savings.
