Prospect and Development Direction of Halogen-free Flame Retardant
Halogen-free flame retardant nylon is the addition of flame retardants in the content of very low or no halogen elements of bromine and chlorine. Halogen-free flame retardant nylon products have excellent flame retardant performance, the flame retardant level reaches UL94V0 level, with low precipitation, anti-dripping, high electrical performance and excellent heat resistance, high CTI value, good electrical performance, high impact strength, environmentally friendly, environmentally friendly, suitable for electrical connectors. The flame retardant properties of the composites were improved by adding brominated flame retardants or halogen-free flame retardants in line with European ROHS standards. This granular nylon can withstand a processing temperature of 260°C. In our use of halogen-free flame retardant nylon granular materials

By adding brominated flame retardants that comply with European ROHS standards or halogen-freeflame retardantIn order to improve the flame retardant properties of composite materials. This granular nylon can withstand a processing temperature of 260°C.
In the process of using halogen-free flame retardant nylon particulate materials, we sometimes encounter some labels, such as UL94V-0, UL94V-2, etc. Flammability UL94 is the most widely used standard for the flammability of plastic materials. UL94V0 can meet five standards and requirements: first, there is no sample after the test flame is taken away, and there is still a flame burning for more than 10 seconds; Second, for each set of 5 samples, after 10 times of ignition, the total combustion time with flame shall not exceed 50 seconds; Third, no samples have been burned to the fixture. Fourth, there are no samples, the drop of burning melted droplets ignited the cotton 12 "below; five, without any sample, continued to red and burn for more than 30 seconds after the second removal of the test flame. Such standards can completely avoid the occurrence of fire.
With the application of nylon engineering plastics more and more widely, more and more varieties of flame retardants, and the development and research of flame retardant technology continue to deepen, flame retardant nylon in the next few decades will go to the following four development directions:
One is the compounding technology of flame retardants. Many flame retardant manufacturers in the world are engaged in the development of new synergistic systems, that is, a variety of flame retardants are compounded to reduce the amount of flame retardants and improve flame retardant performance, which not only reduces the price of flame retardant materials, but also reduces the loss of physical properties. The second is non-halogenation, low toxicity and low halogenation. Many countries have banned or restricted the use of halogen-containing flame retardants, and replaced them with phosphorus, nitrogen-based flame retardants and inorganic flame retardants. Three is multi-functional. In some industries, in addition to the requirements of nylon with flame retardant properties, but also requires such as thermal conductivity, electrical conductivity, antistatic, etc., need to add a large number of other additives to meet the requirements of users. Fourth, the balance of cost and performance. Develop an efficient flame retardant system to reduce the impact of flame retardants on the physical properties of materials, while also reducing pollution and reducing costs.

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.
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.
