What is the amount of Flame Retardant Dicumene generally added?
The addition amount of Flame Retardant Dicumene varies depending on the application scenario, base material type, and required flame retardant level, typically ranging from 5% to 20% by weight.
In polymer materials such as polypropylene (PP) and polyethylene (PE), where moderate flame retardancy is needed (e.g., achieving UL 94 V-2 or HB rating), the addition amount usually falls between 5% and 10%. This range balances flame retardancy and material performance, as excessive addition may cause issues like reduced tensile strength or increased brittleness. For example, in PP injection-molded parts used in household appliances, adding 7-9% Flame Retardant Dicumene can effectively slow down flame spread without significantly affecting the parts' mechanical properties.
For materials requiring higher flame retardancy (e.g., UL 94 V-0 rating) such as engineering plastics like ABS or PC/ABS blends, the addition amount often increases to 10-15%. These applications, common in electrical enclosures or automotive components, demand stricter fire resistance. At this level, Flame Retardant Dicumene works synergistically with other additives (e.g., antimony trioxide in some formulations) to enhance char formation and suppress combustion.
In special cases, such as thick-walled products or materials with high flammability, the addition amount may reach 15-20%. However, this requires careful adjustment of the formulation to avoid negative impacts on processing fluidity. Manufacturers usually conduct pre-tests to determine the optimal dosage, ensuring the final product meets both flame retardant standards and practical performance requirements.
What flame retardant properties does Dicumene offer?
Dicumene exhibits multiple flame retardant properties that make it effective in various polymeric materials. Its primary mechanism involves interrupting the combustion chain reaction in the gas phase. When exposed to high temperatures, Dicumene decomposes to release free radicals that react with reactive species (such as hydroxyl and hydrogen radicals) generated during polymer pyrolysis. This interference slows down or terminates the combustion process, reducing flame propagation speed.
It also contributes to char formation in the condensed phase. By promoting cross-linking reactions in polymer chains, Dicumene helps form a dense, thermally stable char layer on the material surface. This char acts as a physical barrier, blocking heat transfer from the flame to the underlying polymer and preventing further decomposition of the material. The char layer also reduces the release of flammable volatiles, limiting fuel supply to the flame.
Additionally, Dicumene shows good synergistic effects with other flame retardants, such as antimony trioxide. This combination enhances overall flame retardancy, allowing lower total additive levels while achieving higher fire safety ratings (e.g., UL 94 V-0). It maintains effectiveness across a range of processing temperatures, ensuring consistent performance in extrusion, injection molding, and other manufacturing processes.
Moreover, Dicumene helps reduce smoke emission during combustion, which is crucial for improving visibility and reducing toxic gas exposure in fire scenarios. Its balanced performance makes it suitable for applications requiring both flame suppression and material property retention.
Is Flame Retardant Dicumene Compatible with Other Flame Retardants?
Flame Retardant Dicumene, has been used in polymer materials in recent years, widely found in plastics, rubber and other materials. This material is stable in nature, has a high melting point, and is easy to disperse in resin matrices. On its own, it has excellent flame suppression effect. Due to its moderate decomposition temperature, it can release free radical trapping agents in high temperature environments and prevent the spread of combustion reaction chains.
To investigate the compatibility of flame suppressors, its chemical structure and mechanism of action must be identified first. Dimethane is a physical flame retardant, which frees inert gases or dense carbon layers by heat, cutting off the contact between flammable substances and oxygen. If it is used equivalently with phosphorus and nitrogen-based organic flame retardants, such as phosphate esters and melamine, each will develop its own strengths and will not cause violent chemical reactions, and the two will cooperate to improve the flame retardant efficiency. Another example is halogen-based flame retardants, mixed with DKD, which can complement free radicals to enhance the dual effect of smoke suppression and flame suppression.
However, the dosage compatibility cannot violate the proportion. If DKD is used in combination with chlorine-containing organics or metal hydroxides, it is necessary to pay attention to its decomposition characteristics at processing temperature to prevent volatilization loss. As for other additives in the polymer, such as plasticizers, antioxidants, etc., it is rare to encounter DKD with adverse reactions, but the overall formula stability needs to be tested.
Looking at academic reports, dimethane has good compatibility and is suitable for the compatibility of most flame retardant additives. However, the compatibility between different systems should still be verified according to the type of material and end use. If high-temperature and high-speed processing is involved or excellent weather resistance is required, the experiment must be broadened and the dosage and ratio adjusted according to experience. Therefore, dimethane can be compatible with a variety of flame retardants and is widely relied on by the industry. However, in the actual process, it is still necessary to consider rationally and test in detail to ensure the performance and efficiency of the product.
What are the storage and transportation requirements for Flame Retardant Dicumene?
Flame Retardant Dicumene, a flame retardant, is flammable and chemically active, so its storage and transportation must be careful. It should be stored in a cool and dry place, well ventilated, away from fire sources and hot topics, and avoid being in the same place as oxidants, acids, strong alkalis, etc. The storage container should be sealed, and the material should be iron, aluminum, stainless steel or special plastics. Do not use corrosive or flammable materials. During storage, the temperature should be constant to avoid hot sun exposure or severe cold and humidity. Fire, leak and explosion-proof equipment should be installed in the warehouse, and safety warnings should be left in prominent places. Special personnel manage it, and irrelevant personnel are strictly prohibited from entering and leaving.
When handling, the action is light, and it should not be beaten or hit, and it should not be dragged to prevent the package from being damaged and leaking. Its packaging is usually sealed in double-layer bags or barrels, and there are obvious labels on the outside, indicating the name of the product, dangerous characteristics and precautions. Transportation vehicles should be clean, dry, and equipped with rainproof and moisture-proof facilities. During night transportation, there should be warning lights, the speed should be appropriate, and the route should avoid crowded areas and water sources. It should not be mixed with food, feed, reducing agents, etc. In case of strong wind, heavy rain, and hot sun, loading and unloading should be suspended. The loading and unloading site should be equipped with fire extinguisher materials, mainly dry powder and carbon dioxide, and emergency materials should be prepared for leakage. Personnel should wear protective clothing, gloves, goggles, and receive special training.
In case of leakage, it should be collected quickly with inert adsorption materials, sealed storage, and proper disposal. If the environment is polluted, ventilate it in time to dilute the residues. Hazardous gases are released during combustion, so it should be kept away from open flames and hot topics. If the fire starts, it should be extinguished with dry powder and sand, and it is strictly forbidden to sprinkle it with water.
This item is still a hazardous chemical. It must go through transportation procedures, declare and register in accordance with national laws and regulations, and have special management records. Each batch should have a ledger in and out of the warehouse, which should be checked regularly to prevent problems before they occur. Anyone who manages and operates needs to understand its nature and emergency procedures to ensure safe storage and transportation, so as to protect people and property.
