NT CAT9727 is a low-odor reaction type equilibrium catalyst. It is composed of several reactive tertiary amines. It has high activity and is all composed 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. Because the product is a fully reactive catalyst, it has a good low odor. Low fogging performance.
1. NT CAT 9727 is a colorless, transparent to light yellow liquid. It does not need to be prepared and added directly. 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 NT CAT 9727, due to their different catalytic activity and performance, after scientific combination, in the sponge foaming process Compared with triethylene diamine, it has the advantages of balanced reaction and smooth reaction. 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, NT9727 has a surface active effect, which can emulsify and disperse when the materials are mixed, so that the components, especially the water, are better evenly distributed, so that the pore size Become more uniform. At the same time, the heat can be dispersed to avoid excessive concentration, which has a significant anti-burning function. The manufacturer can adjust the proportion of water and water according to the situation, adjust the amount appropriately, adjust the foam cell structure of the sponge, and adjust the hardness of the sponge.
4. Using NT9727 instead of triethylenediamine, the rising process becomes gentle and stable during the reaction. In addition, there is a post-reaction type catalyst component in NT9727, which speeds up the post-curing of the sponge and makes it quicker to form. 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. NT9727 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 NT9727 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 formulation adjustments and effectively reduce costs. With NT9727, the damage to the sponge structure caused by the addition of stone powder can also be relieved to a certain extent.
6. NT9727 is a low atomization catalyst, which emits a sponge with low odor, which is an environmentally friendly product.
7, NT9727 can be used for all soft foams, the dosage is 1/3 of A-33.
NT CAT 9727 is mainly used as a balanced catalyst for polyurethane foam, and is widely used in high-grade soft foam, slow rebound sponge, molded high rebound, etc.
It is especially worth noting that both the odor of NT CAT 9727 itself and the odor of the products made are better than the 9727 catalysts commonly used in the market at present, and the recommended addition amount A -About 1/2 of 33.
