Melamine Cyanurate Masterbatch for Nylon

Melamine Cyanurate Masterbatch is a modified material dedicated to the flame retardancy of nylon (or polyamide). Its main function is to improve the flame retardant properties of nylon materials and ensure that they exhibit good self-extinguishing properties in high temperatures and open flames. Nylon is light and strong, widely used in electronics, electrical appliances, and automotive industries, but its flammability is often a concern for product safety. Today, melamine is compounded with cyanurate, and after high temperature reaction, it is made into melamine cyanurate, which is mixed with a carrier and extruded into a masterbatch, which is easy to blend with nylon resin and used in injection molding, extrusion and other molding processes.
Its mechanism of action lies in the decomposition of melamine cyanurate by heat in case of fire, generating inert gas, and forming a dense protective layer in a high temperature environment to isolate the air, slow down the decomposition of combustibles, and inhibit combustion transmission. If it is matched with a synergistic flame retardant, the effect is better. The product is halogen-free flame retardant, and does not generate corrosive gases during combustion, which is conducive to environmental protection and safety, and has little impact on mechanical properties. Users can adjust the amount of masterbatch added according to the performance requirements of the product, and it is mostly used in the fields of polymer materials such as PA6 and PA66.
Its process is simple, and it can be directly input in various processes such as raw material mixing, dispersion, and granulation. No additional additives are required, which not only ensures uniform flame retardancy, but also facilitates automated production. Melamine cyanurate masterbatch has uniform particle size and good compatibility with the matrix resin. It can reduce dust flying and improve the workshop environment. Its thermal stability is also good, and it is suitable for high temperature injection molding, extrusion and other processing processes.
Its application can not only make electrical connectors, plug housings, motor parts, etc., but also be used in automotive parts, textile fibers and other fields. Melamine Cyanurate Masterbatch is used in the processing of nylon materials. Its main function is to give the material excellent flame retardancy, while taking into account physical properties and processing convenience. It has become an indispensable additive for flame retardant modification of polymer engineering materials.

For the use of Melamine Cyanurate Masterbatch in nylon, the addition ratio needs to be carefully considered. For this product, it is especially suitable for those who use plastic materials with flame retardancy, such as PA6 and PA66. Every time it is matched, it is necessary to consider the mechanical properties, flame retardancy, etc. and the use of the finished product.
For normal work, it is appropriate to take more than 5% to 15% of the quantity. If you pursue UL94 V-0, you may need to push it up to 15%, but it is limited by the thickness of the product. If you ask for V-2 or basic flame retardancy, 5% is acceptable. In order to restrain the cost, it is the best policy to consider the balance of its original strength.
If the amount is added, the flame retardancy is improved, but the brittleness or strength is increased or reduced. It is recommended to micro-mix different formulas in the small size first, and the best нагрузка，. Each level of niches also has the best compatibility. PA6 is more than 9% to 14%, PA66 is more than 10% to 15%. And thin parts, or the whole ratio is required, in order to ensure the quality of the product.
And MC Masterbatch-based granules are mixed, so that they must be homogenized, and the mixing and drying process should not be ignored. If the water is retained, it is easy to produce foam defects. The material ratio is well matched, and more attention should be paid to adding the compatibility of the material to prevent the flame retardant effect.
In other words, the usual addition ratio of Melamine Cyanurate Masterbatch in Nigeria is between 5% and 15%, depending on the proportion of the product, the formula characteristics and the end requirements. Be reasonable and good at it, so that the quality of the product can be used and used.

Melamine Cyanurate (citrulline melamine salt) is a commonly used flame retardant. If it is added to nylon in the form of Masterbatch (masterbatch), especially nylon 6 and nylon 66, its effect on the mechanical properties of nylon products can be described.
First talk about its material properties change. Melamine Cyanurate is dispersed in the polymer matrix, which can effectively improve the flame resistance of the product, and the flame retardant grade can reach UL94 V-0. However, its particle filling and interfacial compatibility are limited, which inevitably affects the force between the original polyamide chains, causing the flexibility and ductility of the polymer to decrease slightly. Because the filler is heterogeneous inside the nylon, forming defect points, it is easy to be the source of cracks when stressed, resulting in a decrease in impact strength. According to the experimental evidence, the amount of filling varies from 5% to 15%, the tensile strength is mostly decreased by 5% -20%, and the impact strength is even more dramatic.
Further examination, if the compatibility of Melamine Cyanurate masterbatch is good, and the surface is treated with a coupling agent or a special dispersion auxiliary agent, the damage to the nylon matrix can be slowed down. Microscopically, if the particle size is fine enough and can be evenly distributed, the degree of plasticity reduction is limited, and the product retains considerable toughness. If the distribution is uneven, local stress concentration is prone to occur, resulting in early failure of the material.
In addition, the non-polar of Melamine Cyanurate has limited synergy with the polar groups of nylon, and the hydrogen bond between the chains is blocked, resulting in a decrease in crystallinity. However, because the thermal decomposition gas product can block heat and oxygen in a high temperature environment, it can improve the heat aging resistance. And its halogen-free, non-migration characteristics will not affect the environmental performance of the product twice.
In summary, although Melamine Cyanurate masterbatch can greatly improve the flame retardant grade of nylon products, it has a certain sacrifice in mechanical properties, especially in the reduction of impact strength and tensile properties. If the compatibility is appropriate and the particle size is fine, the negative impact can be reduced, but it cannot be ignored. Utility users should weigh the balance between flame retardancy and mechanics, and choose the best.

Melamine Cyanurate (melamine cyanurate) is the masterbatch of the nylon phase, and its dispersibility cannot be ignored. This masterbatch is blended with high-quality polymer-based technology, and the granules are homogenized and the surface coating is dense. Melamine cyanurate is also self-contained, and the nylon is good. The masterbatch is processed. The first surface modification is dispersed and blended, so that it can be used in the melting of nylon grease, and it is distributed in a small and small way. The smallest particles are often 10 microns, or even 10 meters, so that the master particle is integrated into the main grain without aggregation, and the coarse precipitation is also achieved, and the finished product color and performance are consistent.
If melamine cyanurate is directly added to the nylon powder, it is easy to reduce the mechanical resistance, roughness of the external surface, and poor performance due to the constant interface force. Today's masterbatch technology has been greatly improved, so that melamine cyanuric acid can be evenly divided into the polymer, improving the fire protection efficiency, and retaining the true color of the material. However, the masterbatch with good dispersion helps to improve the processing and molding process. The flow performance is increased, the surface of the molded product is more smooth, and the surface bubbles and defects are also less. Whether it is good to disperse or not, the flame resistance and mechanical properties of the product are directly improved. The masterbatch method is more respected in the world and the direct method is recommended. Today's products are particularly important for surface activity and dispersion technology, so that the particles can be maintained in the nylon environment without re-aggregation. In other words, melamine cyanuric acid is incorporated into the masterbatch, and its dispersibility is not limited to extensive mixing, which can guarantee the excellence of its function and the quality of the finished product.

Melamine Cyanurate Masterbatch is a special addition of nylon, with uniform properties, usually white or beige particles, which is a wonderful use of flame retardancy. Its storage and transportation should be strictly followed. The outline is as follows:
First discuss storage. A dry and ventilated room must be selected, strictly protected from direct sunlight, in order to avoid light and heat-induced deterioration. The constant temperature of the warehouse room should be below 25 degrees Celsius, do not make sudden rises and drops, so as to avoid performance instability. And it needs to be kept away from water sources, and avoid moisture to prevent it from absorbing water and expanding, causing dispersion and performance to decline. With acids, alkalis, oxidants and other highly volatile and flammable substances, it must be separated from foreign countries, so as not to mix odor and chemical properties. The outer cover packaging should be neat, the mouth of the bag should be sealed tightly, dustproof and anti-impurities, and no foreign objects should be mixed in. The storage period is limited, and the overdue inspection needs to be re-inspected before the quality can be renewed.
Re-discussion of transportation. Use shielding transportation equipment to block the sun from the rain, and avoid being contaminated by the hot sun and rain and snow. Handling must be handled with care, and should not be violently hit to prevent the packaging from being damaged, powdered and spilled. Bumping and shaking will damage its shape. During transportation, it also needs to be separated from various chemicals, and cannot be shared with corrosive and flammable products. In the storage car, it should be properly padded, without high-altitude stacking, to prevent deformation due to extrusion. When arriving at the place used, move it into the designated warehouse as soon as possible, and follow the aforementioned storage method. If the bag body is damaged, it must be collected in time, sorted and disposed of, so that the waste is not lost or contaminated.
All in all, Melamine Cyanurate Masterbatch is a polymer functional material, and its storage and transportation must be carried out with caution. Only dry and ventilated, protected from light and heat insulation, sealed storage, special car distribution, and careful handling can ensure its quality and long-term survival. When used in nylon products, its flame retardant properties are intact, beautiful and harmless. In this way, the benefits of business are endless.
