When foamed panels exhibit uneven cell structure, adjusting the stabilizer is the most efficient solution. By focusing on the following three key areas, quality issues can be quickly improved:

1. Ensure Adequate Thermal Stability
Appropriately increase the stabilizer dosage by 0.2-0.5 parts to prevent uneven melt strength caused by localized thermal degradation during processing. This is the fundamental guarantee for forming uniform cell structure.

2. Optimize Plasticization and Lubrication Balance
Adjust the ratio between stabilizers and lubricants to establish a suitable plasticization window. It is essential to avoid insufficient plasticization, which hinders gas dispersion, as well as excessive plasticization, which affects cell growth.

3. Leverage Synergistic Effects
Select a stabilizer system compatible with the foaming agent, particularly utilizing the activation characteristics of zinc-based stabilizers for AC foaming agents. This ensures precise coordination between gas release timing and melt strength.

By precisely adjusting the stabilizer system, a stable processing environment can be established for the foaming process, fundamentally resolving uneven cell structure and significantly improving product qualification rates.
