The manufacturer shares with you the effects of different doses of organotin catalysts on the aging of polyether-polyurethane foams.
For the one-step polyether-polyurethane flexible foam, the amount of the catalyst and the amount of dibutyltin salt were 0.2%, and then the load retention ratio after aging at 140 °C for 2 hours was 100.
The polyether-polyurethane flexible foam prepared by the second step method, the catalyst and stannous octoate content was 0.5%, and then the load retention rate after aging at 140 ° C for 2 h was 100.
The amount of the third catalyst and dibutyltin salt was 0.15 + 0.05% of the antioxidant, and the one-step polyether polyurethane soft foam was aged at 140 ° C for 2 h with a load retention of 96.
The amount of the third catalyst and dibutyltin salt was 0.2%, and the one-step polyether polyurethane soft foam was aged at 140 ° C for 2 h, and the load retention was 0.
For the fourth prepolymerized polyether-polyurethane flexible foam, the amount of the catalyst and the amount of the amine catalyst were 2%, and the load retention ratio after aging at 140 ° C for 2 hours was 82.
The above is about the effect of several types of organotin catalysts on the aging of polyether polyurethane foams, I hope to help you.
