Flame retardant of polyolefin (PP/PE)
Polyolefin (PP/PE) flame retardant is a functional additive that can be used to flame retardant polyolefin (PP/PE). For polyolefin (PP/PE) flame retardant design, polyolefin (PP/PE) flame retardant has many types, which can be divided into additive flame retardant and reactive flame retardant according to the use method.
Flame retardants are mainly organic and inorganic, halogen and non halogen. Is the organic nitrogen and phosphorus, bromine and compounds represented some inorganic flame retardant, mainly three oxidation two antimony, magnesium hydroxide, aluminum hydroxide, silicon flame retardant system etc..
Generally speaking, organic flame retardant has a good affinity. In plastics, brominated flame retardants occupy an absolute advantage in organic flame retardant system. Although there are many criticisms on environmental protection problems, it is difficult to replace other flame retardants.
In the non halogen flame retardant system of red phosphorus is a good flame retardant, has added advantages of small quantity, high flame retardant efficiency, low smoke, low toxicity and wide use etc.. The use of red phosphorus and aluminum hydroxide, expanded graphite and other inorganic flame retardants, made of composite phosphate / magnesium, phosphorus, phosphorus / aluminum / graphite and other non halogen flame retardant, can greatly reduce the use of flame retardant dosage, so as to improve the plastic products processing properties and physical mechanical properties.
But ordinary red phosphorus are easily oxidized in air, moisture absorption, easy to cause the dust explosion, transportation difficulties, and polymer poor phase defects, the application scope is limited. To make up for this deficiency, in order to expand the scope of application of red phosphorus microencapsulation, we adopt advanced techniques, making Microencapsulated Red phosphorus. Microencapsulation in addition to overcome the drawbacks inherent in the red phosphorus, and has the advantages of high efficiency, low smoke, no toxic gases in the processing, its dispersion, physical and mechanical properties, thermal stability and flame retardant properties were improved.
Looking for a balance point between fire protection and environmental protection is an important node for the future development of flame retardant products. The importance of flame retardants in modern society can not be ignored, but with the introduction of a series of environmental protection policies in Europe, their development and application are restricted to varying degrees. How from the fire threat at the same time in the protection of persons and property, but also can make the potential hazard of flame retardant on the human body and the environment are reduced to a minimum, is the common focus of domestic flame retardant production enterprises, research institutions and downstream of electronic and electrical, building materials, transportation and furniture industry.
Flame retardant chemicals have been successfully used in the fire and flame retardant properties of plastics, reducing the risk and damage to people's lives and property. But adding flame retardants doesn't make plastics nonflammable. Flame retardant requirement is to increase the plastic resistance to human performance, reduce the burning rate. These requirements are the flammability test methods and the basis for industrial testing of flame retardancy of plastics.

Flame retardant TPP has many advantages, such as excellent transparency, softness, bacterial resistance, and water proof, grease-proof, good electric insulation, as well as good compatibility. Flame retardant TPP is mainly used as the flame-retardant plasticizer for cellulose resin, vinyl resin, natural rubber and synthetic rubber. And it may also be used as the flame-retardant plasticizer for glyceryl triacetate thin ester and film, rigid polyurethane foam, phenolic aldehyde resin, and PPO, etc.
Flame retardant TPP is a kind of halogen-free environment-friendly flame retardant with phosphorus element. Most of the products in the market are self-colored flaky crystal, our product is self-colored crystalline powder, and is more soluble in organic solvents. TPP is not soluble in water, but soluble in benzene, chloroform, ether and acetone, and slightly soluble in Z alcohol. Flame retardant TPP is nonflammable with slight aromatic odor and slight deliquescence. The fusion point is about 50 ℃, and fast melts to hoop-shape when heated. The lubricate effect is excellent, and it is often used as the flame retardant plasticize lubricant. What is more, it is used as the flame retardant for many plastics and resins, such as phenolic aldehyde resin, epoxy resin and so on.
Halogen (such as chlorine, Australia), phosphorus and water have the best flame retardancy. Their flame retardancy can also be enhanced by the following synergistic agents, such as antimony, zinc, and other metal salts. The function of flame retardant is realized in many ways. Some of the flame retardants contribute to the formation of a protective layer of phosphorus (phosphorus compounds flame retardants) so that the unburned polymer is separated from the flame and heat source.
Other flame retardants act by changing the chemical mechanism of the flame, i.e., in the vapor phase, to prevent the formation of free radicals (halogenated compounds flame retardants). There are also flame retardants that release their moisture to heat sources (such as water bearing compounds), quench and cool combustion reactions. How to choose a flame retardant correctly, which can make the best performance in plastic, which depends on the stability of flame retardant and the decomposition temperature of polymer.
There are mainly organic flame retardants and inorganic flame retardants, halogen flame retardants and non halogen flame retardants at present. Organic flame retardant with bromine and nitrogen flame retardant and red phosphorus flame retardant and compounds represented some flame retardant, inorganic flame retardant is three oxidation two antimony, magnesium hydroxide, aluminum hydroxide, silicon flame retardant system etc..
Generally speaking, organic flame retardants have good affinity. In plastics, brominated flame retardants occupy an absolute advantage in organic flame retardant system. Although there are many criticisms on the environmental protection of flame retardants, it is difficult to replace with other flame retardant systems.
In the non halogen flame retardant in red phosphorus flame retardant is a good flame retardant, has added advantages of small quantity, high flame retardant efficiency, low smoke, low toxicity, wide application; red phosphorus flame retardant and aluminium hydroxide (mg), expandable graphite and other inorganic flame retardants, made of composite phosphate / magnesium / phosphorus; aluminium; phosphorus / graphite and other non halogen flame retardant, can greatly reduce the use of flame retardant dosage, flame retardant plastic products to improve the processing performance and physical and mechanical properties.
Flame retardants are mainly suitable for plastics with flame retardant requirements, and flame retardants delay or prevent the burning of plastics, especially polymers. The flame retardant makes the ignition time increase, the flame retardant ignites itself, and the flame retardant is difficult to ignite.
Flammable polymers, such as PP, PA, PE, PS, ABS, EVA and PET, PBT, etc., need to be added flame retardants in special applications.
