How to add XPS Flame Retardant Mflam MB E20 and how much to use?
XPS (extruded polystyrene) insulation board is widely used in the construction field, but its flame retardant performance is of great concern. Mflam MB E20 is an efficient and environmentally friendly flame retardant, specially designed for XPS materials. The method of addition needs to follow the process, and take into account the uniform mixing and end point performance.
At the beginning of the stocking stage, the polystyrene raw materials are moderately dried and placed in a mixer. The flame retardant Mflam MB E20 is pre-dispersed in powder form, and the amount should be calculated. Take its conventional dosage, about 2% to 4% of the total resin mass, which can be adjusted slightly according to the flame retardant grade requirements. It needs to be mixed with the main raw materials and mechanically stirred to make it uniform. If the masterbatch method is used, Mflam MB E20 and part of polystyrene are blended as the masterbatch, and then compounded with the raw material, a good dispersion effect can also be obtained.
Then the material is mixed and sent to the extrusion extrusion equipment. Heat up to a suitable processing temperature, heat preservation is sufficient, so that the flame retardant and polystyrene are melted and blended, and there is no gap in each other. In this process, it is necessary to prevent local overheating and avoid the decomposition failure of the flame retardant. After the discharge is molded, it is cooled and cut to form the final product.
When there is a higher demand for the flame retardant level, the amount of addition can be increased, but the excess may affect the mechanical properties and cell structure of the product. The appropriate amount is still 2% -4% most commonly used. The operator should adjust the proportion in time according to the product test results. If the high flame retardant grade above B1 needs to be met, a small amount of synergistic additives can also be added and used with Mflam MB E20.
Finally, the product should be tested and accepted by combustion to ensure that the flame retardant is fully distributed and the performance is up to standard. It can be officially applied. In summary, when using Mflam MB E20 in XPS materials, it should be weighed in strict accordance with the proportion to ensure uniform mixing and control the processing temperature to achieve the best flame retardant effect.

How does XPS Flame Retardant Mflam MB E20 affect the physical properties of XPS materials?
The effect of adding flame retardant Mflam MB E20 to XPS (extruded polystyrene foam board) on its physical properties can be analyzed rationally. XPS is based on polystyrene resin as the main body and is heated and extruded to form a closed-cell honeycomb structure, so it has excellent properties such as light weight, heat insulation and compression resistance. However, its nature is flammable, so it must be modified with flame retardant to meet safety standards.
Mflam MB E20 is a new type of environmentally friendly flame retardant. It is mixed into XPS materials, which can significantly improve its flame retardant grade, making it meet or even exceed the B1 level requirements. However, the doping of flame retardants cannot be ignored, and its changes in the physical properties of XPS are mainly reflected in several ends.
First, the flame retardant particles are mixed with the resin system, which may affect the cell structure of the XPS sheet. If properly dispersed, the cells are uniform and the structure is dense, and the physical properties are lost very little. If the dispersion is uneven, the cells are large and uneven, the structure is loose, the plate density is reduced, and the compressive strength is easy to decrease. Therefore, the process control and the excellent particle size of the flame retardant are really the key. The Mflam MB E20 particle size is moderate, the compatibility with the matrix is excellent, and the dispersion is uniform, so the effect on the cell structure is limited.
Second, in terms of mechanical properties such as compressive strength and flexural strength, the reasonable dosage of Mflam MB E20 has little reduction in the overall mechanical properties of XPS. Experiments show that within the range of commonly used dosage (such as 3% -6%), the compressive strength decreases mostly between 5% and 10%, which is still limited by building and thermal insulation codes. If the dosage is too high, the molecular chain of polystyrene will be blocked, the microstructure will be disturbed, and the performance will drop significantly. The proportion of flame retardants must be strictly controlled to take the balance.
Furthermore, the water absorption and thermal conductivity may also be fine-tuned. The addition of Mflam MB E20 may have a slight hydrophilic end group, but the overall effect on the closure of the cell is limited, so its water absorption does not change much. Thermal conductivity depends on the integrity of the cell structure. If the structure is not greatly damaged, its thermal insulation performance will hardly decrease significantly.
As for weather resistance and dimensional stability, if the flame retardant can be well compatible with the XPS matrix, the material's cold and heat resistance characteristics and dimensional change rate are basically unchanged, and the safety of use can be maintained.
In short, Mflam MB E20 has a significant gain in the flame retardant performance of XPS at a reasonable dosage, but has a limited impact on the physical properties. It is a good strategy to improve the safety level of XPS. Preparation needs to take into account the ratio and process to ensure the balance of physical properties.
