Chemical blowing agents play a vital role in the production of foamed plastics, rubber, EVA, PVC, PE, and other polymer materials. Among the most commonly used products are AC (Azodicarbonamide) Blowing Agent and NC Blowing Agent. Although both are designed to create a cellular foam structure, they differ significantly in decomposition characteristics, processing performance, and cost.
Understanding these differences can help manufacturers choose the most suitable blowing agent for their production process while reducing manufacturing costs.
AC blowing agent, also known as Azodicarbonamide (ADC or ADCA), is one of the world's most widely used chemical blowing agents. It offers a high gas yield and excellent foaming efficiency, making it suitable for applications such as:
Standard AC blowing agents typically decompose at around 190–210°C. However, by using suitable activators or modified formulations, the decomposition temperature can be significantly reduced to meet various processing requirements.
NC blowing agents generally refer to low-temperature chemical blowing agents based on nitroso compounds or specially formulated systems. Compared with conventional AC blowing agents, they begin to decompose at lower temperatures, making them suitable for polymers with relatively low processing temperatures or applications requiring more controlled foaming behavior.
⚙️ For manufacturers, the choice depends on processing temperature, desired cell structure, production efficiency, and overall manufacturing cost.
The answer is yes—in many applications.
With advances in formulation technology, modified AC blowing agents can achieve decomposition temperatures much lower than those of standard AC products while maintaining the high gas yield and excellent foaming performance that AC is known for.
Our Modified AC Blowing Agent Series is specially designed to:
For many EVA, PVC, rubber, and plastic applications, our modified AC blowing agent can effectively replace conventional NC blowing agents without sacrificing product quality.
In most markets, NC blowing agents are generally more expensive than AC blowing agents because of their formulation complexity and more specialized applications. By using a modified AC blowing agent that delivers similar processing performance, manufacturers can significantly reduce raw material costs while maintaining consistent foam quality.
For high-volume production, even a small reduction in blowing agent cost can lead to substantial annual savings.
At YUBO Industry, we manufacture both standard AC blowing agents and modified AC blowing agents for a wide range of polymer applications.
Our modified products are engineered to provide:
Whether you are currently using an NC blowing agent or looking to optimize your production costs, our technical team can recommend the most suitable modified AC blowing agent based on your processing conditions and product requirements.
