How to Choose the Right AC Foaming Agent for PVC Foam

Introduction

In PVC foam production, the choice of foaming agent directly impacts the foam density, smoothness, and performance. Among all types, AC foaming agent (Azodicarbonamide) has become the most popular due to its high gas yield, stable performance, and cost-effectiveness.

However, not every AC foaming agent is the same. Choosing the right grade requires both technical knowledge and a trusted supplier. As a leading manufacturer with over 16 years of experience, Jiangxi Yubo Industrial Co., Ltd. provides tailored AC foaming solutions to help global customers achieve consistent quality at a competitive cost.

What is AC Foaming Agent?

AC foaming agent (ADC) is a chemical blowing agent widely used in plastics and rubber. When heated, it decomposes to release gases such as nitrogen, creating a uniform cellular structure inside PVC foam products.

At Yubo Industrial, we supply AC foaming agents with different particle sizes and decomposition temperatures, ensuring excellent compatibility with PVC foam board production lines.

Main Advantages of AC Foaming Agent

• High Gas Evolution – Generates up to 220–250 ml/g of gas, ensuring efficient foaming.
• Fine Cell Structure – Produces smooth, uniform foam surface.
• Adjustable Performance – Activators can tune decomposition temperature for different processes.
• Wide Applications – From PVC foam board to EVA footwear and automotive parts.
• Cost-Effective – Lower dosage with higher output.

Key Factors to Consider When Selecting an AC Foaming Agent for PVC Foam

When choosing the right grade, consider:

• Decomposition Temperature – Must match PVC processing range.
• Gas Yield – Determines foam density.
• Particle Size – Finer grades ensure uniform distribution.
• Purity & Residue – High purity avoids discoloration.
• Environmental Compliance – Ensure RoHS & REACH standards.
• Supplier Reliability – Partner with experienced manufacturers like Yubo for consistent supply.

Applications Beyond PVC Foam Board

Our AC foaming agents are widely applied in:

PVC pipes

Footwear products

EVA Sheets

Rubber sheets and gaskets

Precautions for Use

• Store in a cool, ventilated, and dry environment.
• Avoid exposure to moisture and direct sunlight.
• Use protective equipment during handling.
• Test compatibility before scaling up production.

Conclusion

Choosing the right AC foaming agent is crucial for producing high-quality PVC foam boards. With the right product and supplier, you can achieve lightweight, durable, and cost-efficient results.

At Jiangxi Yubo Industrial Co., Ltd., we combine 16 years of manufacturing expertise, strict quality control, and professional export service to deliver AC foaming agents that meet global standards.
