Equivalent to FP 2100JC

As an equivalent substitute product of FP 2100JC, Equivalent to FP 2100JC is used in polyolefin plastics. Its flame retardant performance is similar to that of the original product, but there are also slight differences. The core flame retardant mechanism of the two is similar. Both can decompose at high temperatures to produce flame-retardant gases and carbon layers, forming a barrier when a fire occurs, isolating oxygen and heat, and inhibiting the spread of plastic combustion. In the production of polypropylene film, adding the same proportion of Equivalent to FP 2100JC and the original FP 2100JC, after the combustion test, the vertical combustion level can reach V-0 level, and the afterburning time and flame retardant time are almost the same, indicating that the basic flame retardant performance is equivalent. However, upon closer inspection, the decomposition temperature of Equivalent to FP 2100JC is slightly lower than that of the original product, about 5-8℃ lower, which requires slight process adjustments during plastic processing, such as reducing the extrusion temperature by 3-5℃ to prevent premature decomposition and affect the fluidity of the plastic melt. When used in low-density polyethylene pipes, Equivalent to FP 2100JC has slightly better dispersibility. Microscopic observation shows that its particles are more evenly distributed in the plastic matrix, which makes the flame retardant properties of various parts of the pipe more consistent, avoiding the degradation of mechanical properties caused by local aggregation of flame retardants. In addition, in long-term thermal aging tests, both can maintain stable flame retardant performance, but after being placed in an 80℃ environment for 1000 hours, the flame retardant efficiency decay rate of Equivalent to FP 2100JC is 1.2% lower than that of the original product, showing better thermal stability. In general, Equivalent to FP 2100JC can effectively replace the original FP 2100JC. It only needs to fine-tune the process according to the specific plastic type to achieve similar or even better flame retardant effects.

In the preparation of Equivalent to FP 2100JC, the selection of raw materials is as important as the cornerstone of product performance. The slightest deviation may affect the final performance. Its main raw materials include phosphorus compounds, nitrogen synergists and dispersing aids. The quality and ratio of each type of raw material need to be carefully considered. Phosphorus compounds use industrial-grade raw materials with a purity of ≥99.5%. If the impurities contained in it exceed 0.3%, the decomposition temperature of Equivalent to FP 2100JC will fluctuate. If trace metal ions are mixed in, the decomposition temperature may be reduced by more than 10°C, affecting the stability of plastic processing. The selection of nitrogen-based synergists is particularly critical. The molar ratio of specially treated melamine derivatives to phosphorus-based compounds should be controlled at about 1:1.2. An unbalanced ratio will weaken the flame retardant synergistic effect. If the ratio is too high, there will be too many nitrogen-based components, and the amount of gas generated at high temperature will be too large, which may cause dripping when the plastic burns; if the ratio is too low, the proportion of phosphorus-based components is too high, the carbon layer is not formed sufficiently, and the flame retardant effect decreases. The selection of dispersing additives must match the plastic matrix. For polyolefin plastics, fatty acid ester additives can be used to control the particle size of Equivalent to FP 2100JC particles in the plastic to be dispersed below 5μm. If the wrong additive is selected, such as silicone oil additives, it will lead to poor dispersion and agglomeration, affecting the mechanical properties and flame retardant uniformity of the plastic. In addition, the moisture content of the raw materials must be strictly controlled below 0.1%. If the moisture exceeds the standard, bubbles will be generated during the high-temperature preparation process, forming pores inside the product particles and reducing their thermal stability. The moisture content of a batch of Equivalent to FP 2100JC was 0.3%, so when it was used in polypropylene, the flame retardant grade dropped from V-0 to V-1, which shows the key influence of raw material selection on product performance.

The compatibility of Equivalent to FP 2100JC with different types of plastics varies depending on the type of plastic. During processing, the process needs to be adjusted according to the characteristics to ensure product quality. It has better compatibility with polyolefin plastics, such as polyethylene and polypropylene, because their molecular structures are similar. When the addition amount is 15-20%, the melt flow rate decreases less, only 5-8%, after mixing in a twin-screw extruder, and the surface of the product is smooth and there is no precipitation. During processing, it is necessary to pay attention to controlling the screw speed, preferably 300-350rpm. Too high speed will easily cause the flame retardant particles to break and affect dispersion; too low speed will cause uneven mixing and local flame retardant enrichment. When used in polyvinyl chloride (PVC), special attention should be paid to the compatibility of Equivalent to FP 2100JC with plasticizers. Because PVC contains chlorine, it may react slightly with the phosphorus components in the flame retardant, so 0.5% of stabilizer, such as calcium stearate, needs to be added to inhibit the reaction. The processing temperature should be controlled at 160-170℃. Higher temperatures may cause PVC degradation and flame retardant decomposition to promote each other, causing the product to discolor and become brittle. For engineering plastics such as ABS, the compatibility of Equivalent to FP 2100JC is slightly poor, and stratification is prone to occur when the addition amount exceeds 18%. At this time, the flame retardant and ABS powder need to be premixed in a high-speed mixer for 10-15 minutes, and the mixing temperature should be controlled at 60-70℃. The friction heat is used to slightly melt the surface of the flame retardant particles to enhance the bonding force with ABS. The mold temperature needs to be increased to 80-90℃ during processing to reduce the internal stress of the product and avoid cracking due to compatibility issues. Regardless of the type of plastic it is compatible with, Equivalent to FP 2100JC must be dried before processing, and the moisture content must be controlled below 0.05% to prevent bubbles from being generated during processing, affecting the appearance and performance of the product.

When storing Equivalent to FP 2100JC, environmental factors such as temperature and humidity, light, and surrounding materials may affect its stability, and careful prevention and control is required. In terms of temperature, the warehouse temperature needs to be maintained at 15-30℃. If it is higher than 35℃ for a long time, slow oxidation may occur inside the product, causing the content of flame retardant active ingredients to decrease. A test shows that after 6 months of storage in a 38℃ environment, the active ingredients decrease by 2.3%, resulting in a decrease in the flame retardant grade when used in polypropylene. Therefore, ventilation and cooling equipment should be enabled in summer to avoid the influence of high temperature in the afternoon. The influence of humidity is more significant. Although the hygroscopicity of Equivalent to FP 2100JC is low, it will still slowly absorb moisture when the ambient humidity exceeds 60%, causing the particles to agglomerate and the dispersion to decrease. There was a batch of products that were stored in a warehouse with a humidity of 65% for 3 months. The product showed slight agglomeration and needed to be crushed before use, which increased the production cost. Therefore, the warehouse needs to be equipped with a dehumidifier to strictly control the humidity below 50%. Monitoring should be strengthened on rainy days to ensure that the ground is dry, the cargo stack is raised by more than 30cm, and it is 10cm away from the wall to prevent the influence of moisture on the wall. In terms of light, direct sunlight should be avoided. Long-term exposure to ultraviolet rays will cause the flame retardant surface to degrade and affect its thermal stability. Warehouse windows should be equipped with sunshades or light-proof storage should be adopted. A comparative experiment shows that the thermal decomposition temperature of Equivalent to FP 2100JC stored in direct sunlight is 4°C lower than that of Equivalent to FP 2100JC stored in light-proof storage. The surrounding storage materials should also be noted. They should not be stored in the same warehouse with strong acids and strong bases to prevent the interaction of volatile gases. For example, if they are stored in the same warehouse with concentrated hydrochloric acid, HCl gas will be adsorbed on the surface of the product, which will cause its pH value to decrease. When used in PVC plastics, it may accelerate the degradation of plastics. During storage, sampling and testing are required every month to observe the state of particles, measure pH value and thermal stability, and deal with abnormalities in time to ensure the storage stability of Equivalent to FP 2100JC.

Equivalent to FP 2100JC In the reuse of recycled plastics, the flame retardant performance may be affected by multiple factors and needs to be dealt with in a targeted manner. After multiple melt processing of recycled plastics, the temperature rises and falls repeatedly, which may cause Equivalent to FP 2100JC to partially decompose. For example, after three extrusions of recycled polypropylene, the effective ingredients of the flame retardant are lost by about 8%, and the afterburning time is prolonged. At this time, 3-5% of Equivalent to FP 2100JC needs to be added to make up for the loss and ensure that the flame retardant grade meets the standard. Other impurities may be mixed in recycled plastics, such as paper, metal, and different types of plastics. Impurities interact with Equivalent to FP 2100JC and affect the performance. If polyester plastics are mixed in, the ester bonds they contain will react with the phosphorus components in the flame retardant, reducing the flame retardant efficiency. It is necessary to strengthen sorting during recycling and use density separation to remove polyester impurities to achieve a purity of more than 95%. If alkaline detergent is used in the cleaning process of the recycling process, Equivalent to FP 2100JC may be partially hydrolyzed. A test shows that after cleaning with a detergent of pH=10, the flame retardant efficiency decreases by 12%. Therefore, the pH value of the detergent needs to be controlled between 7-8 during cleaning, and a neutral detergent should be used to reduce the impact on the flame retardant. In addition, the molecular weight of the recycled plastic is reduced and the melt fluidity changes, which may affect the dispersion of Equivalent to FP 2100JC. The processing technology needs to be adjusted, such as increasing the screw speed by 10-15% to enhance the shear force so that the flame retardant is evenly dispersed. For plastics that have been recycled many times, it is recommended to appropriately increase the addition ratio of Equivalent to FP 2100JC, adding 2-3% more than the new material, and conduct a combustion test to verify to ensure that the recycled plastic products can still reach the specified flame retardant level and achieve a balance between resource recycling and safety performance.
