As a key material in the PVC foaming industry, azodicarbonamide (AC foaming agent) demonstrates exceptional performance in product lightweighting and functionalization through its precise thermal decomposition control mechanism. It has become an indispensable additive in modern PVC foaming processes.

Core Technical Advantages:

1. Precise Temperature-Controlled Foaming System
The AC foaming agent undergoes controlled thermal decomposition within the range of 195-215°C, releasing gases such as nitrogen. By adding specific activators (e.g., zinc compounds), the decomposition temperature can be precisely adjusted to 160-200°C, achieving perfect synchronization with PVC processing temperatures and ensuring accurate control of the foaming process.

2. Excellent Foaming Characteristics
With a high gas yield of 220-240 ml/g, the decomposition products are non-toxic and harmless. It reduces the density of PVC products to 0.6-0.9 g/cm³, forming a uniform and fine closed-cell structure (closed-cell rate >90%), significantly enhancing the thermal insulation, soundproofing, and cushioning properties of the products.

3. Broad Process Adaptability
Suitable for various processing techniques, including free foaming, skin foaming, and compression molding foaming. It exhibits excellent compatibility with PVC systems, reducing product weight while maintaining mechanical properties. Widely used in building insulation, packaging materials, automotive interiors, and other fields.

Application Value:

• High foaming efficiency with significant cost-effectiveness

• Decomposition residues do not affect product performance

• Excellent synergy with various additives

• Environmental performance meets modern industrial requirements

Usage Guidelines:
Recommended dosage: 0.5-2.0 phr, adjustable based on foaming ratio requirements. It is advised to use in combination with foaming modifiers and stabilizers, with processing temperatures controlled between 170-200°C. Ensure uniform dispersion during use to avoid premature decomposition due to localized overheating.

With its stable decomposition characteristics and outstanding foaming performance, the AC foaming agent provides a reliable lightweighting solution for PVC products, playing a critical role in driving innovation in PVC foaming technology and product upgrades.
