Flame retardant system
The flame retardant, which endows the combustible polymer with the non-flammable functional auxiliaries, mainly aimed at the flame retardant design of the polymer materials; There are many types of flame retardants, which are divided into additive flame retardant and reactive flame retardant.
Flame retardants are mainly organic and inorganic, halogen and non-halogen. Organic is a series of flame retardants, which are represented by bromine, nitrogen and red phosphorus and compounds. The inorganic is mainly antimony trioxide, magnesium hydroxide, aluminum hydroxide, and silicon systems.
In general organic flame retardant have good affinity in plastic, bromine flame retardants occupy absolute advantage in the organic flame retardant system, although on the issue of environmental protection "criticism" multiterminal but has been difficult to replace other flame retardant system.
In the non-halogen flame retardant system, red phosphorus is a good flame retardant, with low additive quantity, high flame retardant efficiency, low smoke, low toxicity and wide application. Red phosphorus and aluminium hydroxide, expanded graphite and other inorganic flame retardants, use compound phosphate / / aluminum, magnesium, phosphorus, graphite and other non halogen flame retardant, can use flame retardant dose reductions and thus improve the processing performance and physical and mechanical properties of the plastic products.
However, ordinary red phosphorus is easily oxidized and hygroscopic in air, which can cause dust explosion, difficulties in transportation, and poor solubility of macromolecular materials. Application scope is limited. In order to make up for this deficiency, in order to enlarge the application range of red phosphorus, we adopted the foreign advanced micro - capsule coating process, which made it a micro - encapsulated red phosphorus. Red phosphorus microcapsules except to overcome the inherent disadvantages of red phosphorus, and has high efficiency, low smoke, do not produce poisonous gas in the processing, its dispersion, physical and mechanical properties, thermal stability qualitative and flame retardant properties were increased and improved.
Trimethyl phosphate (TMP)
Cas No:512-56-1
HS Code HS: 29199000
The most important indicator of product: colorless transparent liquid,colorless transparent liquid Content ≥ 99.5%, moisture ≤ 0.2, the acid value ≤ 0.02, Chroma ≤ 20
Raw materials: phosphorus oxychloride reacted with methanol in the presence of potassium carbonate to produce phosphoric acid trimethyl ester.
Belong to several categories of dangerous goods: Currently Trimethyl phosphate (TMP) general cargo exports are not dangerous.
Trimethyl phosphate (TMP) use is mainly used in medicine, pesticides, solvents and extractants, used as a solvent, extraction, determination of zirconium and GC stationary liquid, the ester is used in medicine and pesticide solvent and extractant. Pesticide intermediates. In Japan, Trimethyl phosphate use as anti stain of textile oil and polymer, flame retardant additive for lithium ion battery.
Trimethyl phosphate is currently the main market in India, mostly for textile auxiliaries, the products are mainly exported to Japan, South Korea, Thailand, India.

Finding the balance between fire protection and environmental protection is an important node for future development of flame retardant products. The importance of flame retardants in modern society cannot be ignored. However, with the introduction of a series of environmental policies in Europe, the development of the flame retardants has been restricted to varying degrees. How to protect persons and property from fire threat at the same time, also can make the flame retardant to minimize the potential risk to the human body and environment, is the domestic flame retardant production enterprises, research institutes and downstream electronics electrical, building materials, transportation and furniture and other common focus of the industry.
Flame retardant chemicals have been successfully used in the anti-ignition and flame retardant effects of plastics, reducing the danger and damage to human life and property. But adding flame retardants does not make plastic an incombustible material. The requirement of flame retardant is to increase the resistance of plastic to human performance and reduce combustion speed. These requirements are the basis of combustible performance test methods and industrial testing of plastic flame retardation.
Halogens (such as chlorine, Australian), phosphorus and water have the best flame retardation. Their flame retardancy can also be enhanced by the following synergies, such as antimony, zinc and other selected metal salts. The effect of flame retardants is realized in many ways. Some flame retardants help to produce a protective coking (phosphor flame retardant) that insulates the unburned polymer from the flame and heat source.
Other flame retardants work by changing the chemical mechanism of the flame, which is to prevent the formation of free radicals (halogen compounds) in the vapor phase. There is also a flame retardant that releases water into a heat source (such as a hydrating compound), quenching and cooling. How to correctly select a flame retardant so that it can perform best in the plastic, depending on the stability of the flame retardant and the decomposition temperature of the polymer.
Flame retardants are mainly organic flame retardants and inorganic flame retardants, halogen flame retardants and non-halogen flame retardants. Organic fire retardant agent is the bromine series, nitrogen flame retardants and red phosphorus flame retardants and compounds represented by some of the flame retardant, inorganic flame retardants mainly antimony trioxide, aluminum hydroxide, magnesium hydroxide, such as silicone flame retardant flame retardant system.
