Manufacturers share with you the effect of different doses of organotin catalysts on the aging of polyether-polyurethane foams.

For the one-step polyether-polyurethane flexible foam, the amount of catalyst and the amount of dibutyltin salt was 0.2%, then the load retention rate was 100 after aging at 140° C. for 2 hours.

The second one-step polyether-polyurethane flexible foam, the catalyst and the amount of stannous octoate 0.5%, then the load retention rate was 100 after aging at 140 °C for 2h.

The third catalyst and the amount of dibutyl tin salt 0.15 + antioxidant 0.05%, one-step polyether polyurethane soft foam aging at 140 °C for 2h load retention rate of 96.

The third catalyst and the amount of dibutyltin salt 0.2%, one-step polyether polyurethane soft foam aging at 140 °C for 2h after the load retention rate of 0.

For the fourth prepolymerized polyether-polyurethane flexible foam, the amount of catalyst and amount of amine catalyst was 2%, then the load retention rate after aging at 140° C. for 2 hours was 82.

The above is about several types of organotin catalyst impact on the aging of polyether polyurethane foam, I hope to help you.
