Phenomenon: stomata are randomly distributed throughout the foam.
Solution:
1. Increase the concentration of tin catalyst
2. Increase the pressure and make the sponge structure slightly thick
3. Reduce air injection and agitator speed
4. Reduce the temperature of ingredients
5. Check the raw materials for silicon or oil lubricant contamination
6. Check whether the shaft seal of foaming machine head is damaged
7. Clean agitator room / Interior
8. Increase settling time of raw materials
9. Increase angle of drop plate
10. Reduce nozzle and pipe size
11. Check the machine for air leaks
