NT CAT9727 is a low odor reactive equilibrium catalyst that is a complex of several reactive tertiary amines with high activity, all composed of amines, so there are no variations or differences in concentration. In this way
precise control of amine dosage can be achieved in production, improving the stability of the production process. Since this product is a fully reactive catalyst, it has excellent low odor and low atomization properties.
1, NT9727 is a colorless transparent to light yellow liquid, no need to prepare, add directly, its catalytic dosage is equivalent to solid amine. Since it is composed entirely of amines, there are no variations or differences in concentration. In this way, precise control of the amine dosage can be achieved in production and the stability of the production process can be improved.
2, NT9727 in the five tertiary amines, because of their catalytic activity and performance of different, after the scientific combination, used in the sponge foaming process, compared with triethylene diamine has the advantages of a balanced reaction, the reaction is smooth and so on. Thus, it can reduce the density gradient of sponge, improve the quality of cross-chaining, reduce the accumulation of dosage, and improve the performance of sponge in all aspects.
3, NT9727 has a surface-active role in the mixing of materials to play an emulsifying and dispersing effect, so that the components, especially water, better distribution, so that the pore size becomes more uniform. At the same time, the heat can be dispersed to avoid over-concentration, thus it has a significant anti-burning core function. Manufacturers can adjust the ratio of water and according to the situation, the appropriate adjustment of the amount of sponge, adjust the sponge bubble hole structure, adjust the sponge hardness.
4、Using NT9727 to replace triethylene diamine, the rising process becomes gentle and smooth during the reaction. In addition, NT9727 has a post-reaction catalyst component, which makes the sponge post-cooking faster, faster molding. The qualification rate of sponge is also greatly improved, and the cutting part of sponge is reduced, which reduces the production cost of sponge to a certain extent.
5, NT9727 for octanoic acid stannous process operating width is very large, generally compared with triethylene diamine, the operating width of tin can be increased by +0.03. At the same time the use of NT9727 can make the TDI index adjustment range increased. It is possible to reduce the amount of TDI by adjusting the formulation to reduce the cost effectively. The use of NT9727 can also play a certain role in alleviating the damage to the sponge structure caused by the addition of stone powder.
6, NT9727 is a low atomization catalyst, the sponge emitted low odor, is an environmentally friendly product.
7、NT9727 can be used in all soft foam, the dosage is 1/3 of A-33.
NT CAT 9727 is mainly used as a balanced catalyst for polyurethane foam, which is widely used in high-grade flexible block foam, slow rebound sponge, molded high rebound and so on.
It is especially worth noting that both the odor of NT CAT 9727 itself and the odor of the products made are superior to the 9727 catalyst commonly used in the market at present, and the recommended additive amount is about 1/2 of A-33.
