Catalyst 9727/Polyurethane catalyst 9727

  1. 9727 is a colorless, transparent to light yellow liquid, which is added directly without preparation, and its catalytic dosage is equivalent to that of solid amine. Since it is composed entirely of amine, there is no variation or difference 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, 9727 in the five tertiary amines, because of their catalytic activity and performance are different, after the scientific combination, used in the sponge foaming process, compared with triethylene diamine has the advantages of balanced reaction, smooth reaction, etc.

Stability and other advantages. 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, 9727 has a surface-active role in the mixing of materials to play the role of emulsification and dispersion, 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, avoiding over-concentration, so that it has a significant anti-burning core function. Manufacturers can adjust the ratio of water and methylene chloride according to the situation, and adjust the dosage of methylene chloride appropriately to regulate the pore structure of the sponge, to

The whole sponge hardness.

4、Using 9727 to replace triethylene diamine, the rising process becomes gentle and smooth when reacting. In addition, 9727 has a post-reaction catalyst component, which makes the sponge post-cooking speed up, molding

Fast. The qualified rate of sponge is also greatly improved, reducing the cutting part of sponge, which reduces the production cost of sponge to a certain extent.

5, 9727 for octanoic acid tin process operating width is very large, generally compared with triethylene diamine, tin operating width can be increased by +0.03. At the same time, the use of 9727 can make the TDI index of the adjusting range increased.

This may be adjusted over the formula to reduce the amount of TDI to effectively reduce costs. With 9727, the sponge structure damage caused by the addition of stone powder can also play a certain role in alleviating the damage.

6, 9727 is a low atomization catalyst, issued by the sponge low odor, is an environmentally friendly products.

7、9727 can be used in all soft foam, the dosage is 1/3 of A-33.

Storage and transportation:
