聚氨酯胺催化剂A-1

 

胺催化剂A-1主要用于软质聚醚型聚氨酯泡沫塑料的生产,也可用于包装用硬泡。胺催化剂A1对水的催比效力 特别强,因此可使泡沫密度降低。它用于控制产生气体的反应的功效约占80%,用于控制凝胶反应的 功效约占20%。该催化剂活性高,用量少,调节该系列的用量,可控制发泡上升和凝胶时间。胺催化剂A1与有机锡催化剂共用,能使泡沫塑料的生产宽容度明显地提高,确保在生产中不致因操作不小心或计量系统的微小误差导致不必要的质量问题,生产出优质的软质泡沫塑料。 胺催化剂A1被广泛用于制造聚氨酯泡沫塑料的各种配方中,特别适用于生产高回弹、半硬泡和低密度泡沫塑料。

Amine catalyst A1

Amine catalyst A1 is mainly used in the production of soft polyether polyurethane foam, and also in the hard foam for packaging. The catalytic effect of amine catalyst A1 on water was particularly strong, so the foam density could be reduced. It controls about 80% of the reactions that produce gases, and about 20% of the reactions that control gels. The catalyst has high activity and low dosage. By adjusting the dosage of this series, the rise of foaming and gelation time can be controlled. The common use of amine catalyst A1 and organotin catalyst can obviously improve the production tolerance of foamed plastics, so as to avoid unnecessary quality problems caused by careless operation or small errors in the measurement system, and to produce high quality soft foamed plastics. Amine catalyst A1 is widely used in various formulations for the manufacture of polyurethane foams, especially for the production of high rebound, semi-rigid foam and low density foams.
