What Is AC Foaming Agent? Applications, Properties, and Benefits Explained

In the world of polymer processing, lightweight, durable, and cost-effective materials are in high demand. One of the key components that helps achieve these qualities is the AC foaming agent. Widely used in the plastics and rubber industries, AC foaming agents play a crucial role in the production of expanded materials, improving product performance while reducing costs.

In this blog, we’ll explore what AC foaming agents are, their key properties, applications across industries, and the advantages they offer to manufacturers.

What Is AC Foaming Agent?

AC foaming agent—short for Azodicarbonamide (ADC)—is a widely used chemical blowing agent. It is a yellow to orange crystalline powder that decomposes when heated, releasing gases such as nitrogen, carbon monoxide, carbon dioxide, and ammonia. These gases form a cellular structure in the material, giving it a foamed or expanded form.

AC foaming agent is primarily used in PVC, EVA, PE, rubber, and other thermoplastics, providing a lightweight structure while maintaining mechanical strength.

Key Properties of AC Foaming Agent

Decomposition Temperature: Typically between 200–220°C, but can be adjusted using activators.
Gas Yield: High gas output (around 220–240 mL/g), ideal for efficient foaming.
Fine Cell Structure: Produces uniform and consistent foam with good surface quality.
Odorless and Non-Toxic (when processed correctly): Suitable for a wide range of industrial applications.
Compatibility: Works well with a variety of polymers and additives.

Common Applications of AC Foaming Agent

PVC Foam Boards and Sheets
Used in construction and furniture for lightweight, strong, and cost-effective panels.
Shoe Soles (EVA, Rubber)
Provides cushioning and flexibility, commonly found in sports and casual footwear.
Automotive Interior Parts
Helps reduce vehicle weight while maintaining durability and aesthetics.
Wire and Cable Insulation
Enhances insulation properties without adding bulk or weight.
Packaging Materials
Used in creating shock-absorbing foams for electronics, food, and industrial products.
WPC & SPC Flooring
Improves dimensional stability and sound insulation of wood and stone plastic composite flooring.

Benefits of Using AC Foaming Agent

Cost Efficiency: Reduces the amount of raw material used by creating a foamed structure.
Weight Reduction: Lighter products translate into easier transportation and installation.
Improved Thermal and Acoustic Insulation: Ideal for building materials and automotive applications.
Enhanced Product Appearance: Creates a smooth, uniform surface finish.
Environmentally Friendly Options Available: Low-odor, non-toxic variants align with green manufacturing practices.
