What is the chemical structure and molecular formula of Piperazine Pyrophosphate Mflam 1420?
Piperazine Pyrophosphate, Chinese name piperazine pyrophosphate, commercial name Mflam 1420, is actually an organophosphorus flame retardant. Its chemical structure is composed of piperazine (Piperazine) and pyrophosphate (Pyrophosphate, P 2O O) combined. Piperazine is a six-element nitrogen-containing heterocycle with the molecular formula C H < unk > N < unk >. The ring has dinitrogen relative, the structure is stable and it is easy to react with acids. Pyrophosphate is formed by removing a molecule of water from diphosphate, and its chemical formula is [P ² O]. The phosphorus atoms are connected by an oxygen bridge, which has strong complexation and flame retardant properties. The combination of the two results in the formation of piperazine pyrophosphate. The basic molecular formula is C H < unk > N ³ · H P ³ O, and the general formula is also C H < unk > N ³ P ³ O.
In terms of its structure, the piperazine ring uses nucleophilic nitrogen atoms as ligands and is connected with pyrophosphate anions through ionic and hydrogen bonds. In actual products, most of them are salts, such as Piperazine Pyrophosphate Salt. Its structure is briefly described as follows: On the nitrogen side of one molecule of piperazine ring, it is electrically neutralized with two pyrophosphate anions to form a stable structure. Pyrophosphate is connected by an oxygen bridge of diphosphorus, and each phosphorus atom is in a tetrahedral configuration, which binds to external oxygen. In this way, the whole molecule contains C-N, P-O, N-H and other bonds, and the flame retardant effect is significant.
The molecular weight of piperazine pyrophosphate is about 252.1 g/mol, and it is a white powder and easily soluble in water. It is a commonly used additive flame retardant in polymers such as polyvinyl chloride and polyolefins. The phosphorus and nitrogen elements in the structure can cooperate in the combustion process to form a stable carbon layer, isolate heat sources and air, and inhibit the emission of smoke and toxic gases, which meets the needs of modern materials for flame retardant safety.
In summary, the chemical structure of piperazine pyrophosphate Mflam 1420 can be briefly described as a combination of piperazine cation and pyrophosphate anion, and its molecular formula is C H N ² P ² O, which is very popular in the field of flame retardancy. In addition, because of its halogen-free environmental protection, it is widely used in the fields of electronics, electrical and construction, making it an excellent additive for efficient and safe flame retardancy.
What is the flame retardant effect of Piperazine Pyrophosphate Mflam 1420 in applications?
Piperazine Pyrophosphate, known as Mflam 1420, is a new type of phosphorus-nitrogen environmentally friendly flame retardant used in the field of polymers in today's world. Its physical and chemical properties are mild, non-toxic and tasteless, the decomposition temperature is high, and the volatilization is extremely small, so it is an ideal flame retardant for a variety of polymer materials such as polyolefins, polyesters, polyurethane and cellulose.
In terms of its mechanism of action, Mflam 1420 can decompose and release phosphoric acid and a variety of non-flammable gases when exposed to high temperatures in fire. Phosphoric acid dehydrates to form polyphosphoric acid, which can react with the surface of the coated material to form a carbonized layer. This layer is dense and solid, shielding oxygen and external heat sources, and inhibiting further decomposition of combustibles. Compounding it in the gas phase releases non-flammable molecules, dilutes the oxygen concentration in the combustion zone, blocks the free radical chain reaction, and weakens the flame expansion speed, so the flame potential is controllable and the fire is difficult to spread.
In addition, Mflam 1420 is different from traditional halogen flame retardants. Few toxic corrosive gases escape during combustion, so it is environmentally friendly. Its hydrolysis resistance makes it easy to disperse in various polymer systems, which does not damage the original mechanical properties, and does not cause migration and precipitation. It is often used in combination with other auxiliary flame retardants, which has a good synergistic effect and better effect. It can greatly improve the oxygen index of the material and easily pass UL 94 V-0, V-2 and other international flame retardant certifications.
In practical applications, Mflam 1420 is applied to polypropylene, polyester fiber, paint or wood, which can make its products drip without bright flame under fire, do not melt, and greatly increase the carbon residue rate. After being heated, only the surface is coked, and it will not burn deeply, and the fire will stop. And because of its stable molecular structure and undiminished durability, it is suitable for many fields of electronic device shells, architectural decoration, and textile fabrics, which greatly enhances the safety of use and has outstanding fire protection efficiency.
To sum up, the power of Mflam 1420 lies in the generation of carbon layer flame retardant, gas phase barrier, environmentally friendly and low toxicity, and stable performance. It is the best choice among the flame retardant measures in the field of polymers today.

What is the recommended amount of Piperazine Pyrophosphate Mflam 1420 in different materials?
Piperazine Pyrophosphate, Chinese name piperazine pyrophosphate, trade name Mflam 1420, is a novel and efficient halogen-free flame retardant, widely used in many polymer materials, such as polypropylene (PP), polyethylene (PE), polyester (PET, PBT), polyamide (PA), ethylene-vinyl acetate copolymer (EVA) and thermoplastic polyurethane (TPU). The application amount depends on the substrate used, the required flame retardant properties and the synergistic effect of related excipients. However, after many tests, the recommended amount commonly used in the industry is as follows:
For polypropylene, if you want to reach UL94 V-0 level, it is recommended to add 22% to 25% of the total formula quality, supplemented by an appropriate amount of synergistic agents (such as talc powder or antimony barium powder, about 2% to 3%), which can greatly improve the flame retardant performance. For polyethylene products, the commonly used addition amount is 18% to 22%, which increases or decreases slightly with the thickness of the product and the process. It should be matched with a suitable processing temperature to avoid the decomposition or precipitation of crystalline materials due to excessive heating.
If used in polyesters (including PET and PBT), the addition amount should be 16% to 20%. Considering its own crystallinity and polarity, the flame retardant dispersion is particularly critical, and it should be used in combination with an appropriate amount of compatible agent to avoid physical properties degradation. As for polyamide materials (such as PA6, PA66), the addition amount is mostly 15% to 20%. When compounding high polar resins, attention should be paid to moisture control and processing rheology to prevent color change or mechanical properties deterioration.
EVA materials are mostly used for cables, and the amount of flame retardant is about 22% to 28%. However, EVA has a special molecular structure, which requires the self-extinguishing ability of flame retardants, and is often combined with a little inorganic flame retardant (such as aluminum hydroxide, antimony trioxide). TPU thermoplastic elastomers are often controlled in the range of 15% to 18% depending on the processing method and application, in order to achieve both flame retardancy and elasticity.
In special applications such as surface coating, Mflam 1420 can also be used as an additive. The dosage must be combined with the actual process and flame retardant grade performance requirements, usually fluctuating between 10% and 20%. Overall, when using Mflam 1420, it is necessary to weigh material compatibility, product appearance, mechanical strength and other aspects in order to achieve the best comprehensive effect.
In summary, the recommended addition amount of Piperazine Pyrophosphate Mflam 1420 in different polymer materials, although there is a general reference, is finally adjusted according to the actual formula. Supplemented by optimized processing technology, the ideal flame retardant level can be achieved, so that the product has both safety and performance beauty.
