Its function is especially famous for flame retardancy, and it is widely used in the protection field of various materials. Its physical and chemical properties are stable, with high decomposition temperature, and it is difficult to burn in case of fire. It is suitable for a variety of resin systems. Modern industrial manufacturing, plastics, rubber, fibers, coatings and other products rely on this material to increase their safety.
Melamine polyphosphate is one of the environmentally friendly flame retardants. It does not contain halogens and does not release toxic gases when burned. Therefore, it is suitable for modern society that strictly abides by environmental protection norms. Its mechanism of action is to explain the release of phosphoric acid when heated, participating in the flame retardant reaction in the vapor phase and condensed phase of the polymer surface, which can not only isolate the air, but also promote carbonization, forming a dense carbon layer to isolate the heat source.
In plastic products, such as polypropylene, polyamide (nylon), polyethylene, etc., it is often blended with this material to significantly improve the flame retardant grade of the material. It is used in electronic and electrical components, automotive interiors, engineering plastics, etc., to prevent fires and maintain stable performance. The textile industry also adopts Mflam MPP blending treatment to enhance the combustion resistance of fabrics and meet various safety standards. In the construction field, it is mixed with paints, adhesives and sealing materials to prevent the spread of fire and ensure the safety of the public.

Both high efficiency and environmental protection, it is the leader in the current flame retardant chemical materials. In summary, melamine polyphosphate is widely used in industrial production and daily products for fire safety due to its superior performance, ranking among the most important flame retardants, and it is increasingly important.
What is the heat resistant temperature of Melamine Polyphosphate Mflam MPP?
Melamine Polyphosphate Mflam MPP, is a halogen-free flame retardant, which is mostly used for the modification of plastics, rubber and polymer materials. Its chemical properties are stable, it is not easy to decompose at high temperature, and it is environmentally friendly. The heat-resistant temperature refers to the material that can maintain its structure and function for a long time in a high temperature environment without decomposing. Under normal conditions, the thermal decomposition temperature of melamine polyphosphate is about 320 degrees Celsius to 350 degrees Celsius. When the temperature rises again, ammonia and water are gradually released, and the polymer main chain is broken, resulting in complete carbonization.
When this substance is heated, it begins to swell on the surface, forming a porous carbonized layer that blocks external heat, oxygen and combustibles, which helps to improve the flame retardant and heat resistance of the material. However, in long-term application environments, if there is a hot topic load, it is generally recommended that the working temperature should be controlled below 250 degrees Celsius in order to effectively exert its flame retardant performance and maintain its physical properties. Beyond this temperature, although it will not decompose rapidly, its function will gradually be damaged, which is manifested in the decline of mechanical properties and electrical insulation properties.
The structure of melamine polyphosphate is crosslinked by melamine molecules and phosphate ions. The molecules are stable with hydrogen bonds or coordination forces. When the temperature rises, slow-release ammonia can be used to resist flame. The phosphorus component forms polyphosphoric acid at high temperature, which makes the material appear to expand and further isolates the combustion environment.
As for the commercially available Mflam MPP products, although their specifications vary, most of the heat resistance properties are also in this category. In practical application, it is necessary to refer to the standard data provided by various suppliers to ensure that the material is suitable. Its flame retardant mechanism has both the effects of endothermic decomposition and combustion isolation. It is actually a halogen-free flame retardant additive commonly used in the polymer field.
In summary, melamine polyphosphate is a high-temperature resistant and high-quality flame retardant material. The thermal decomposition temperature is between 320 and 350 degrees Celsius. If used at a constant temperature, it should be controlled below 250 degrees Celsius to ensure its long-term use.
How much Melamine Polyphosphate Mflam MPP is generally added?
In the past, man-made materials were always concerned about their flammability, so in polymer materials, flame retardants may be added for security. Today's Melamine Polyphosphate Mflam MPP is a phosphorus-nitrogen environmentally friendly flame retardant. Its chemical properties are mild and heat-resistant, suitable for a variety of resins, such as polypropylene, polyamide, epoxy, polyurethane, etc.
To apply Mflam MPP, it is necessary to clarify the appropriate amount. Cover each substrate, the flame retardant requirements vary. If polypropylene is used as an example, if it is to achieve UL94 V-0 grade flame retardant, the addition of Mflam MPP is usually between 25% and 35% (mass fraction). This amount can not only significantly improve the oxygen index, but also maintain the mechanical properties of the material. If it is only to reach V-1 or V-2 grade, the addition amount can be slightly reduced, about 15% to 20%. If it is used for glass fiber reinforced composites, the thermal stability of the matrix is enhanced, and the amount of Mflam MPP can be slightly lower. However, if it is used for polyamide plastics, for excellent flame retardant performance, the addition ratio is usually between 15% and 25%. In addition, the actual addition depends on the material thickness, product shape and application environment.
When Mflam MPP is used in combination with other synergistic agents such as expansion aids, carbon aids, and anti-dripping agents, the dosage can often be reduced to achieve a higher flame retardant grade. There are also synthesizers who use a small amount of additives such as melamine and aluminum hydroxide to harm the mechanical strength of the material.
If the amount is increased or higher than a certain limit, the mechanical properties of the material may be damaged, so the chemist should choose the ratio carefully in the experiment. When using it, it is appropriate to conduct a small test first, adjust the reference appropriately, and then use it on a large scale. At this point, in order to be concise, it is said that the dosage of Mflam MPP needs to be adjusted according to material properties, flame retardant grade and use situation, and the maximum rate is 15 to 35%. However, it must not be generalized, and it must be determined by referring to actual tests.
is based on the materials used by today's people, emphasizing both safety and environmental protection. Although Mflam MPP is excellent, its advantage lies in the reasonable addition and the use of it to show its effectiveness.
