Catalyst 9727

Catalyst 9727

9727 is a colorless transparent to light yellow liquid. It is directly added without preparation and its catalytic dosage is equivalent to solid amine. Since it is all composed of amines, there is no change or difference in concentration.

In this way, precise control of the amount of amine can be achieved during production, and the stability of the production process can be improved.

The five tertiary amines in 9727, due to their different catalytic activities and performances, are used in the foaming process of sponges after scientific combination. Compared with triethylenediamine, they have a balanced reaction and flat reaction

Stable and other advantages. Thereby reducing the density gradient of the sponge, improving the quality of the cross-linking, reducing the amount of accumulation, and improving the performance of all aspects of the sponge.

9727 has a surface active effect, which acts as an emulsifying and dispersing effect when the materials are mixed, so that the components, especially moisture, are distributed more evenly, so that the pore size becomes more uniform. At the same time, the heat is able to

Disperse to avoid excessive concentration, thus having a significant anti-burn core function. The manufacturer can adjust the ratio of water and dichloromethane according to the situation, appropriately adjust the amount of dichloromethane, adjust the cell structure of the sponge,

Whole sponge hardness.

Use 9727 instead of triethylenediamine. During the reaction, the ascent process becomes gentle and stable. In addition, there is a post-reactive catalyst component in 9727, which accelerates the post-aging of the sponge and forms

fast. The pass rate of the sponge is therefore greatly improved, reducing the cutting part of the sponge, which reduces the production cost of the sponge to a certain extent.

The operating width of 9727 for stannous octoate is very large, generally compared with triethylenediamine, the operating width of tin can be increased by +0.03. At the same time using 9727 can increase the adjustment range of TDI index.

This may reduce the amount of TDI properly through formula adjustments and effectively reduce costs. With 9727, it can also alleviate the damage to the sponge structure caused by the addition of stone powder

9727 is a low-atomization catalyst with low odor of sponge, which is an environmentally friendly product.

9727 can be used for all flexible foams, the dosage is 1/3 of A-33. A
