Three Steps to Solve Uneven Foaming in PVC Foamed Shoe Soles
Oct 23 2025

Experiencing uneven bubbles in foamed shoe soles? Don't worry, adjusting the stabilizer properly can solve the problem. Just keep these three key points in mind:

1. Choose the Right Stabilizer

  • Calcium-zinc stabilizers are recommended

  • Use about 3 kg of stabilizer per 100 kg of raw materials

  • A small amount of soybean oil can be added to enhance the effect

2. Control the Temperature

  • Maintain processing temperature between 165-175°C

  • Avoid temperatures that are too high or too low

  • Monitor in real-time with a thermometer

3. Prepare Auxiliary Materials Properly

  • Add an appropriate amount of processing aids

  • Choose suitable foaming agents

  • Avoid using too much or too little lubricant

In Simple Terms:
Stabilizers act like a "calming pill," ensuring a smooth foaming process. With accurate dosage, suitable temperature, and proper combination with other materials, you can produce shoe soles with evenly distributed bubbles.
