Polyurethane catalystA-1 is composed of bis(dimethylaminoethyl) with a mass fraction of 70% A solution of ether and 30% dipropylene glycol (DPG).
1. Physical and chemical properties
The typical physical and chemical properties of A-1 catalyst are: flash point (closed/open cup) 74℃/77℃, refractive index (25℃) 1.4346, vapor pressure (21℃) 1.3Pa.
2. Characteristics and uses
A-1 catalyst is mainly used for soft The production of polyether polyurethane foam can also be used as rigid foam for packaging. A-1 has a particularly strong catalytic effect on water, so it can reduce the foam density. It is about 80% effective in controlling gas-producing reactions and about 20% effective in controlling gel reactions. The catalyst has high activity and low dosage. By adjusting the dosage of this series, the foaming rise and gel time can be controlled. A-1 is shared with organotin catalyst, which can significantly improve the production tolerance of foam plastics, ensuring that unnecessary quality problems will not be caused by careless operation or small errors in the metering system during production, and high-quality soft plastics can be produced. Styrofoam.
A-1Polyurethane CatalystCatalysts are widely used in various formulations for manufacturing polyurethane foams, and are especially suitable for the production of high resilience, semi-rigid foam and low-density foams.
