Corrugated Plastic Case Suppliers Introduces The Characteristics Of Halogenated Flame Retardant
Corrugated Plastic Case Suppliers introduces the difference between different flame retardants for hollow board:
1. Halogen-free flame retardant of PP hollow board, the definition of "halogen-free": at this stage, the industry generally puts chlorine (Cl) and bromine (Br) in commodities with a rate below 900ppm, and the total number of the two is below 1500ppm. The product is defined as a halogen-free product. Comparing the relevant regulations of national standards or the halogen-free regulations of internationally renowned large companies, we can find that the types of halogens they supervise and the scope of their content manipulation are basically the same. Halogen-free flame-retardant hollow board is currently a hot topic for research. It has the advantages of micro-toxicity, low-smoke and halogen-free cables, low erosion, no dripping, and small impact on the surrounding environment. With the increasing awareness of environmental protection. , Halogen-free flame-retardant hollow board is an inevitable development trend.
2. Halogenated flame retardant of PP hollow board, halogenated flame retardant of hollow board is compared with halogen-free flame retardant, its flame retardant is generally a commodity of traditional bromine antimony flame retardant management system, with filling Low dosage, high flame-retardant efficiency, good production and processing characteristics, etc. However, halogen flame-retardant hollow boards emit a lot of smoke, dioxins and other harmful substances in the event of a fire. After the spread of the ban on the fuel, the future of the halogen-containing flame-retardant hollow board was darkened.
3. Low halogen flame retardant of PP hollow board. Low halogen flame retardant is a new flame retardant method in recent years. The definition of low halogen is very vague and there is no definite requirement specification. Compared with halogen flame retardant, The halogen content of low-halogen flame retardants is much lower; compared with halogen-free flame retardants, the halogen content of low-halogen flame retardants is higher. The basic principle of the low-halogen flame-retardant flame retardant of PP hollow board is based on the PP igniting and dripping to remove the heat, and with the extinguishing effect of the pneumatic valve, and then achieve the purpose of flame retardancy, the amount of low-halogen flame retardant added is 1 -5 parts, low-halogen flame-retardant masterbatch is added in 4-8 parts, with less filling, high flame retardant efficiency, no moisture absorption, no precipitation, resistance to aging and thermal embrittlement, low erosion, and smoke It has the advantages of small quantity and good production and processing characteristics. It is a flame retardant for PP hollow board with higher price.
Through the above introduction, Corrugated Plastic Agriculture Box Manufacturers hopes that you can simply refer to the content of this article in future use.
