What conditions should flame retardants be used in foam plastics?

With the gradual expansion of the scope of application of rigid polyurethane foam, there are higher requirements for the performance of foam, in which flame retardant is the most important problem. Rigid polyurethane foam is widely used in refrigerator, freezer box insulation layer, cold storage, refrigerated trucks and other insulation materials, buildings, storage tanks and pipeline insulation materials, its most fundamental disadvantage is flammable. Now and Dongguan Hongtaiji Flame Retardant Materials Co., Ltd. to understand the application of flame retardants in the foam should have what conditions? 1, the performance of the foam impact is small; 2, the amount of addition

Now and Dongguan Hongtaiji Flame Retardant Material Co., Ltd. to understand the application of flame retardants in foam should have what conditions?
1, the impact on the performance of foam plastic is small;
2, the amount of addition is small and the effect is good;
3, the flame retardant effect does not decrease with the passage of time;
4, non-toxic or very small toxicity to ensure safe use;
5. Good miscibility with raw materials;
6, liquid flame retardant viscosity can not be too large;
7. No corrosion of equipment and devices;
8 The price is low.
These are the requirements for the use of flame retardants in foamed plastics, please understand them carefully.

Zhongke Flame Retardant Organization Watches 20 Closing Ceremonies

On the morning of October 22, 2022, members of Zhongke Flame Retardant New Materials Co., Ltd. watched the closing ceremony of the 20th Congress under the leadership of General Manager Wang Ligui.

What are the reasons for the failure of flame retardant after adding aluminum hydroxide flame retardant?

Everyone knows that there are two common flame retardants. Today we are going to talk about only one of them. Aluminum hydroxide flame retardant is an environmentally friendly halogen-free flame retardant, which can be widely used in fabrics, wood, plastics, and rubber., Polyurethane and other industries have ideal flame retardant effect. In the process of industrial application, it is found that flame retardant failure occurs when aluminum hydroxide flame retardant is added. The following are the reasons for the failure of aluminum hydroxide flame retardant, how to prevent it, how to deal with the operation, and restore the original function.

As a flame retardant, magnesium hydroxide also need to improve what aspects?

When it comes to flame retardants, everyone is familiar with them. Although we usually have less contact with them, we can know what they are used for from the name. Have to talk about magnesium hydroxide, we all know that its main presentation state is a granular, at present, the market sales of magnesium hydroxide particle size is larger, part of the commodity particle size up to tens of microns, immediately used as a flame retardant, poor dispersion, the physical properties of raw materials greater harm. In industrial production, physical grinding methods are generally used to reduce the particle size to 1 micron. The surface of magnesium hydroxide has high polarity and is easy to agglomerate. As the compatibility of refractory materials and polymer substrates, it not only reduces its flame retardant grade, but also causes more serious harm to the physical properties of raw materials.
