Historical Development
Polyethylene, since the end of the 19th century, has gradually become a practical material due to its excellent properties. However, it is flammable, and it will burn in case of fire. Those who need to be prevented are increasingly urgent. The first use of halogen flame retardants began in the 20th century, and bromine and chlorine compounds were gradually adopted and became popular in industry. However, it caused disasters to the environment and became increasingly toxic. By the end of the 20th century, the concept of environmental protection increased day by day, and new flame retardants such as phosphorus and nitrogen came out one after another, gradually replacing old halogen products. Nano flame retardants have revived, with both high efficiency and green use, enhancing the flame retardancy of polyethylene. Various synergistic agents also cooperate to improve the overall performance. Today, polyethylene flame retardants are becoming more and more new in technology, taking into account safety and environmental protection, which is a great concept of evolution over

Preparation Method
High-density polyethylene is selected as the base, with bromine and phosphorus-based flame retardants as raw materials, supplemented by additives such as magnesium hydroxide and antimony trioxide, and mixed uniformly. At the beginning of the melt blending method, the polyethylene is first melted at high temperature, followed by slow injection of flame retardant, stirring to disperse it in the matrix. Then extrusion granulation is used, constant temperature and pressure are applied, and the polyethylene is further fused with the flame retardant component, and the granulation is cooled and formed. If the phosphorus-based flame retardant needs to be catalyzed by adding acid, the polyphosphate is formed through a condensation reaction, and then dispersed in the polyethylene by mechanical force. The reaction mechanism is that the catalyst activates the surface, promotes the formation of phosphorus-oxygen bonds between internal molecules, improves flame retardancy, and gives the effect of forming a The whole process is orderly, which not only guarantees the performance of polyethylene, but also requires flame retardant safety.
Chemical Reactions & Modifications
Polyethylene is lazy and difficult to self-retardant. It is chemically modified to increase its fire resistance. Commonly used flame retardants such as phosphorus, nitrogen, bromine, or aluminum oxide and magnesium hydroxide are added to the polyethylene matrix. When it enters fire and is heated, it releases phosphoric acid, which can form a carbon layer, isolate oxygen, and inhibit combustion. Magnesium hydroxide and aluminum oxide also decompose thermally, absorb heat and release water, and cool down the polyester flame. Bromide is trapped by free radicals and cuts off the combustion chain. Additives or surface treatment to achieve uniform dispersion without compromising the properties of the matrix. Complex synergy effect, compound application, is conducive to flame retardancy and maintenance of function. These chemical modifications are the key to fire protection of polyethylene materials.

Application Area
Polyethylene is widely used in the world and is widely used in factories. However, it is flammable and cannot be ignored. Nowadays, flame retardant additives are used to enhance its fire resistance. They are widely used in various fields and are actually important security devices. For example, wires and cables are relied on for flame retardant to prevent the spread of fire and ensure the safety of communication and power supply. For example, in the construction industry, thermal insulation materials and various types of plastic sheets, flame retardant additives are applied, which can not only enhance the safety of the structure, but also delay the fire and reduce the loss of property and life. In automobile manufacturing, interiors and wiring harnesses are taken in large quantities to prevent accidents, so that the transportation can be carried out without fear of being burned. Packaging containers and home appliance shells also benefit. Flame retardant additives are widely used in many fields of industry and civil use, protecting the safety of the national economy and people's livelihood, and ensuring harmony and development.
Research & Development
Polyethylene is a commonly used polymer material in the world. It has excellent properties, but its flammable disadvantages need to be overcome urgently. So people with lofty ideals dedicated themselves to studying the method of flame retardant additives. At first, halogen-based compounds were introduced, which had good flame retardant effect, but their smog toxicity and environmental pollution gradually attracted criticism from the academic community. Later, halogen-free flame retardant additives were developed, and phosphorus-based, nitrogen-based and inorganic fillers were tried to be both safe and efficient. In the meantime, there are applications of nano-materials, which can be added in small amounts to significantly improve the flame retardant effect. Today's products not only retain the original physical properties of polyethylene, but also have excellent flame retardant effect, which is safe and environmentally friendly, and is widely used. However, innovation continues, and the process and formula still need to be refined, striving for the ultimate in performance, cost and compatibility, so as to contribute to the sustainable development of society.
Toxicity Research
Flame retardants added to polyethylene can increase the fire resistance of the material, but its toxicity cannot be ignored. Looking at all kinds of flame retardants, such as bromine, phosphorus and inorganic, bromine is particularly commonly used, but it is easy to release bromide when incinerated, which is harmful to the environment and human body. Its smoke contains toxic particles such as dioxins and furans, which can cause respiratory diseases, inhibit liver and kidney function, and even cause cancer. Although phosphorus compounds are slightly inferior, they can also cause chronic poisoning when accumulated; when moved to the environment, they can have ecological disturbances. Inorganic flame retardants such as aluminum hydroxide, magnesium, etc., are less toxic, but the large amount may affect the mechanical properties. All of these should be carefully debated for their toxicity in production and application, taking into account fire prevention and health and safety. They should not focus on the advantages and ignore the disadvantages.
Future Prospects
Polyethylene flame retardant additives are popular in the world today, but their development is not endless. Looking at the rise of the current environmental protection wave, human beings are increasingly green and low-carbon, and additives will also tend to be non-toxic and degradable, and their efficacy will benefit the environment. With the increasing technology, nanomaterials or bio-based components will be integrated into the flame retardant system, doubling its flame retardant performance without reducing its mechanical beauty. In the future, the formula must be exquisite, which not only preserves the essential advantages of polyethylene, but also endows it with high efficiency and self-extinguishing, and new flame retardant technologies will emerge as the times require. Material modification, or from extensive to intelligent, responds to environmental changes, and self-adjusts the flame retardant effect. Industry-university-research collaboration, innovation is endless, and the goal is to achieve the best, and the times progress. It is necessary to see stronger flame retard

What are the Main Types of Flame Retardant Additives for Polyethylene?
Polyethylene is soft in nature and is widely used in many utensils. However, its nature is flammable, and it is difficult to burn the flame in case of fire. Therefore, people mostly apply flame retardant additives to increase its safety. There are many types of flame retardant additives, and there are mainly several used for polyethylene. First, halogens, especially bromine and chlorine, are commonly used. This kind of material is taken from organic molecules, and when burned, halogen atoms are released, trapping free radicals, breaking the chain of combustion, and the effect is obvious. However, its smoke and corrosion, or environmental concerns, are often replaced by environmentally friendly methods in this world.
Second, phosphorus-based flame retardants include both organic phosphorus and inorganic phosphorus, such as phosphates and phosphate esters. These additives precipitate phosphoric acid at high temperatures to form a carbon layer, which coats the surface of polyethylene, isolates oxygen and heat sources, and has the dual flame retardant function of gas phase and condensed matter. Of the three, nitrogen-based additives, especially melamine and its derivatives, are known for their ability to generate non-combustible gases with thermal decomposition products, dilute combustible gases, and cooperate with phosphorus elements to enhance the carbonization effect.
There are also inorganic metals, such as aluminum hydroxide and magnesium hydroxide. This additive acts in a physical way to remove water from burning, absorb heat and cool down, dilute combustible gas, and generate metal oxides to contain fire. Although its dosage is large, it is safe and non-toxic, so it is highly respected when the demand for green environmental protection is becoming increasingly apparent.
In addition, nanomaterials such as nano-clays, carbon nanotubes, etc., although not traditional flame retardants, are added in small amounts to significantly improve the thermal stability and flame retardant properties of the material, and improve the mechanical properties of polyethylene. There are also co-effectors, plasticizers, etc., or main agents to increase work, or to extend the life of the material.
Overall, the flame retardant of polyethylene, with the help of many additives, or chemical, or physical, or dual-effect, has its own strengths. When selecting, it is important to consider its cost, performance and environmental impact, so that it can be used for a long time and avoid danger.
