Catalyst 9727

1, 9727 is a colorless, transparent to light yellow liquid, without preparation, directly added, and its catalytic dosage is equivalent to solid amine. Since it is all made up of amines, there are no changes and differences 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.
2, the five tertiary amines in 9727, because of their different catalytic activity and performance, after scientific combination, they are used in the foaming process of sponge, compared with three Ethylene diamine has a balanced and flat reaction
Stable and other advantages. Thereby reducing the density gradient of the sponge, improving the quality of cross-linking, reducing the amount of accumulation, so that all aspects of the sponge performance can be improved.
3, 9727 has a surface active effect, and plays an emulsifying and dispersing effect when the materials are mixed, so that the components, especially the moisture, are better evenly distributed, so that the pore size becomes more Evenly. At the same time, the heat gets
Disperse, avoid excessive concentration, thus has a significant anti-core burning function. Manufacturers can adjust the ratio of water and dichloromethane according to the situation, appropriately adjust the amount of dichloromethane, and adjust the foam cell structure of the sponge.
The hardness of the entire sponge.
4. Using 9727 instead of triethylenediamine, the ascent process becomes gentle and stable during the reaction. In addition, there is a post-reaction type catalyst component in 9727, which speeds up the post-curing and shaping of the sponge
Quick. As a result, the qualification rate of the sponge is greatly improved, and the cutting part of the sponge is reduced, which reduces the production cost of the sponge to a certain extent.
5, 9727 has a very large process operation width for stannous octoate. Generally, compared with triethylenediamine, the operation width of tin can be increased by +0.03. Using 9727 at the same time can increase the adjustment range of the TDI index.
In this way, it is possible to appropriately reduce the amount of TDI through formula adjustment and effectively reduce costs. With 9727, the damage to the sponge structure caused by the addition of stone powder can also be relieved to a certain extent
6 and 9727 are low-atomization catalysts, which emit a sponge with low odor and are environmentally friendly products.

7, 9727 can be used for all soft foams, the dosage is 1/3 of A-33.
