PP flame retardant characteristics and process you know?
PP flame retardant is made of imported materials, is a new type of high efficiency containing Br (bromine), P (phosphorus) N (nitrogen) and other elements of the reaction type flame retardant. PP high efficiency flame retardant PP high efficiency flame retardant is made of imported materials, is a new type of high efficiency containing Br (bromine), P (phosphorus) N (nitrogen) and other elements of the reaction type flame retardant. Compared with the traditional added brominated flame retardants (decabromodiphenyl ether, tetrabromobisphenol A, octabromo ether, octabromo bis S ether, TBC, etc.), the addition amount is small, the flame retardant effect is good, no need to add antimony trioxide, and the bromine content is low (in the modified products, a few

PP efficient flame retardant
PP high efficiency flame retardant is made of imported materials, is a new type of high efficiency containing Br (bromine), P (phosphorus) N (nitrogen) and other elements of the reaction type flame retardant. Compared with the traditional added brominated flame retardants (decabromodiphenyl ether, tetrabromobisphenol A, octabromo ether, octabromo bis S ether, TBC, etc.), the addition amount is small, the flame retardant effect is good, no need to add antimony trioxide, and the bromine content is low (the halogen-free requirement can be almost reached in the modified products). At the same time, the flame retardant also has very excellent processing thermal stability.
No precipitation, water resistance, light aging resistance, non-toxic and other characteristics.

3. Main Applications
This product can be widely used in polypropylene (homopolymerization, copolymerization) flame retardant.
PP halogen-free flame retardant
PP special environmental flame retardant is a nitrogen phosphorus flame retardant is designed for polypropylene and the development of halogen-free, intumescent flame retardant. It is polymerized by a synergistic effect of phosphorus-containing nitrogen-containing chemicals, has good compatibility in polypropylene, has little effect on the mechanical properties of plastics, and has excellent processing stability during processing. PP special environmentally friendly flame retardant is different from halogen-containing flame retardants. In the combustion process, a dense expanded carbon layer is produced to achieve the purpose of heat insulation and flame retardant air, without irritating hydrogen halide gas and black smoke. It is an environmentally friendly flame retardant. Method of use
1. After mixing with PP, it is added to the extruder. The amount of addition is 8%-10% by mass;
2. The processing temperature is recommended to be 180-200 ℃. Due to the good thermal stability of this product, if the specific process needs, it can also be appropriately improved;
3. When mixing and extruding with PP, it is recommended to use a twin-screw extruder, preferably on a parallel and co-rotating twin screw for granulation;
Processing technology:
Heating zone 1 2 3 4 5 6 7 8
Temperature (℃)140 150 175 185 185 185 180
It is recommended not to add any other inorganic fillers, because the filler will destroy the carbon layer structure and affect the flame retardant effect;
2. It is recommended not to add stearate lubricants;
3, if you add antioxidants and light stabilizers, it is appropriate to use organic antioxidants and light stabilizers;
4, PP special environmental protection flame retardant mixed with other additives to be carefully evaluated.

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.
