PolyurethaneAmine CatalystA–1
Amine CatalystA–1It is mainly used in the production of flexible polyether polyurethane foam and can also be used in rigid foam for packaging.Amine Catalyst A1It has a particularly strong catalytic effect on water, so it can reduce the foam density. It is used to control the reaction that generates gas for about 80% of the time, and the efficiency for controlling the gel reaction is about 20%. The catalyst has high activity, The dosage is small. Adjusting the dosage of this series can control the foaming rise and gel time. The amine catalyst A1 is shared with the organotin catalyst, which can significantly improve the production tolerance of foam plastics and ensure that no careless operation will occur during production. Or small errors in the metering system lead to unnecessary quality problems and produce high-quality flexible foams. Amine catalyst A1 is widely used in various formulations for manufacturing polyurethane foams, and is especially suitable for the production of high-rebound, semi-rigid foams. and low-density foam.

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.
