Flame retardant manufacturers tell what flame retardant methods are used in rubber
Flame retardant is a common additive used to stop or reduce the combustion possibility of combustibles. For the flame retardant of polymers, with the development of flame retardants and the strengthening of people's awareness of fire prevention, flame retardants are required to achieve flame retardant effect to both flame retardant and smoke suppression.
flame retardantA common additive used to stop or reduce the possibility of burning combustibles. For the flame retardant of polymers, with the development of flame retardants and the strengthening of people's awareness of fire prevention, flame retardants are required to achieve flame retardant effect to require flame retardant and smoke suppression at the same time.
When selecting the flame retardant technology and flame retardant system of rubber flame retardant elastic materials, the environmental effect must be considered. Therefore, the program of flame retardant rubber used abroad is to achieve fire prevention, low smoke, low toxicity, and environmentally friendly.
Rubber flame retardant methods generally have the following several.
(1) physically adding flame retardants that play a flame retardant effect in the gas phase or condensed phase or at the same time in two phases, and usually using a composite synergistic flame retardant system composed of a variety of flame retardants;
(2) adding into the carbon agent and carbon catalyst, in order to improve the rubber under high heat into carbon rate;
(3) Blending with other polymers (including rubber);
(4) by physical or chemical means, the progress of rubber crosslinking degree;
(5) compounding with nano-inorganic into rubber/inorganic nanocomposites;
(6) the introduction of flame retardant elements (halogen, phosphorus, nitrogen, etc.) in rubber macromolecules to prepare essential flame retardant rubber.
However, at this stage, flame retardant rubber is still dominated by this method, and the second and third methods are also used from time to time, but the latter three methods, either due to the process, or due to cost, or due to other reasons, are still in the laboratory research stage.

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.
