It can be seen from the above table that with the increase in the amount of the heat-sensitive catalyst SA-102, the tensile strength and elongation of break of the polyurethane foam have been improved. This is because the activation of the thermally sensitive catalyst SA-102 can improve the cell structure of the polyurethane foam, making it more uniform and delicate, thereby improving the mechanical properties of the foam.

| 1.5 | 0.029 |
It can be seen from the above table that with the increase in the amount of the heat-sensitive catalyst SA-102, the thermal conductivity of the polyurethane foam gradually decreases. This is because the activation of the thermally sensitive catalyst SA-102 can improve the cell structure of the polyurethane foam, making it more uniform and delicate, thereby reducing the thermal conductivity of the foam and improving its thermal insulation performance.
3.4 Effect on the aging resistance of polyurethane foam
Activation of the thermosensitive catalyst SA-102 can significantly improve the aging resistance of polyurethane foam. Specifically manifested as:

|---|---|---|
| 0 | 80 | 75 |
| 0.5 | 85 | 80 |
| 1.0 | 90 | 85 |
| 1.5 | 95 | 90 |
It can be seen from the above table that with the increase in the amount of the heat-sensitive catalyst SA-102, the tensile strength retention rate and elongation retention rate of the polyurethane foam after aging have increased. This is because the activation of the thermally sensitive catalyst SA-102 can improve the cell structure of the polyurethane foam, making it more uniform and delicate, thereby improving the aging resistance of the foam.
