What are the main uses of BASF Melagard MPP?
BASF Melagard MPP is originally a polymer material additive made by BASF in Germany. It is also known as a polybenzotriazole ultraviolet absorber. It covers its unique chemical structure and can effectively contain the erosion of ultraviolet light in polymer polymers. Countertype, its homologous substitute, imitates its original characteristics and uses a similar chemical structure to provide an alternative for the market without compromising performance. The main use of this product is in the field of polymer chemicals, especially in the plastics and resin industries.
Ultraviolet radiation is sufficient to cause polymer chain fracture, causing the material to become brittle, discolored, and lose its original luster and mechanical strength. Countertype of BASF Melagard MPP is mixed into plastics, rubber, polyolefins, ABS and other materials, which can absorb the high-energy ultraviolet spectrum of sunlight, convert it into heat energy, and resolve the harmful excited state reaction of the material, so its protective effect is very obvious. This will help the material to prolong its life and prevent rapid aging under atmospheric exposure. Such as automotive exterior parts, plastic steel doors and windows for construction, agricultural films, wire and cable sheaths, all rely on its protection to endure.
Furthermore, the electronics industry and packaging industry also need such additives from time to time to ensure that the products are exposed to strong light or sunlight for a long time, with bright colors and stable performance. Its wide application covers almost all artificial materials that need to be exposed to sunlight. For products that need to maintain transparency, Countertype of BASF Melagard MPP is more respected for its excellent thermal stability and low self-chromaticity. It can also be used with antioxidants and anti-aging agents to enhance the synergy effect, which is an indispensable help for modern polymer products.
To sum up, the main use of Countertype of BASF Melagard MPP is to protect polymer materials from the destruction of sunlight and ultraviolet rays, so that its performance and appearance can be extended. The application field is wide, which is the protection of new materials, promotes technological progress, and serves all contemporary industries.
What are the physical and chemical properties of BASF Melagard MPP?
BASF Melagard MPP is a special anti-UV additive for polymer materials. It is widely used in plastics, rubber and other products, especially for enhancing UV stability. If you talk about the physical and chemical properties of its countertype, the cover can be described in detail as left:
First, the appearance is mostly light yellow or white powder, uniform texture, fine and easy to mix in a variety of polymer matrices. The relative density is about 1.35~ 1.40, the melting point is generally between 150~ 160 degrees Celsius, and the suitable processing temperature is wide, which can ensure that the physical properties of the product are not lost during molding. Excellent thermal stability, can withstand high temperature processing environment, and has strong resistance to decomposition. Easy to disperse and will not agglomerate into blocks, so it is often added in small amounts, which has good results. The chemical properties are stable, no irritating odor, and no harmful impurities such as halogens and heavy metals, which meets the requirements of green environmental protection.
Second, the chemical structure belongs to diphenyl ethylene derivatives, and the molecule contains unique substituents, which can efficiently absorb ultraviolet rays with wavelengths of 290 to 400 nanometers. This function is obtained under long-term exposure, effectively preventing the polymer backbone from UV degradation and improving the service life of the product. It has good compatibility with polyolefin, polycarbonate, polyester and other polymer materials, and is also suitable for engineering plastics, fibers, films, coatings and other fields. It can also tolerate acid and alkali, is not easy to hydrolyze, and has a neutral chemical reaction. Therefore, it coexists with the matrix for a long time, and will not migrate and precipitate, which has no effect on the physical and mechanical properties of the product.
Third, the particle size is extremely small, which is conducive to full contact with the polymer and enhances the light stability. The addition ratio is flexible, generally 0.1 to 0.5%, depending on the different systems. Daily storage should be protected from light, dry, and cool, both to prevent moisture and to avoid failure.
In short, BASF Melagard MPP equivalents not only have excellent physical and chemical properties, but also are easy to process and have wide compatibility. They are actually additives for polymer materials to resist UV aging.
Countertype of BASF Melagard MPP
In the industrial production of polymer materials and plastics, protective agents are used to extend the life of products and improve their anti-aging properties. Melagard MPP produced by BASF is actually a polymer protective aid containing phosphonate esters, which is widely used in polyolefins and other materials and is known for its stability and high efficiency. However, when pursuing alternatives or equivalent Countertype products, the first thing to pay attention to is the comparison of its performance with the original product, taking into account its dispersion, thermal stability and solubility.
When it comes to the amount of Melagard MPP added, the range varies according to the material system and application. For common polymer resins such as polypropylene, polyethylene, ABS, etc., it is generally recommended to add an amount of about 0.05% to 0.3% of the matrix resin; if the requirements for photothermal and weather resistance are higher, it can be increased to 0.5% as appropriate, but it should not be too much. Due to overdose or system migration and precipitation, it will damage its performance and even affect the appearance of the product.
The timing of addition should also be cautious. Usually, before the polymer melt extrusion and injection molding process, the Countertype protective agent is evenly mixed with the resin masterbatch. Or used as a masterbatch, used in the blending of this product, and then dispersed after secondary processing, which can make the addition effect particularly uniform. During this period, attention should be paid to temperature control. Excessive temperature may cause the protective agent to decompose and lose its effectiveness. If it can be used in combination with UV absorbers, the protective effect can be improved.
Overall, the recommended amount of Countertype of BASF Melagard MPP is 0.1% to 0.3%. If there is any variation in the properties of the material, it should be tested and verified, and the amount should be adjusted to meet the required performance of the product. The only thing to consider is the balance between dose and efficacy, which is too much. The protection of polymers is not limited to being unchanged from time to time, but also needs to be flexible with the characteristics of the material and the actual process.
In conclusion, a good protective agent should be used in a small trial to obtain the best ratio, and then pushed back to large-scale production to achieve twice the effect with half the effort.
Can Countertype of BASF Melagard MPP replace the original BASF product?
BASF Melagard MPP is a polymer material UV-resistant additive made by BASF in Germany. It is widely used in plastics and rubber products to prevent sun aging, and its performance is outstanding. However, there are many "Countertype" on the market today, which is translated as a benchmark product, and its formula and use are imitated for replacement. If you want to completely replace the original BASF Melagard MPP with Countertype, there are many considerations.
The original BASF Melagard MPP has exquisite production technology, guaranteed formula patents, stable quality, and little difference between batches. Its physical properties table and light aging curve are supported by detailed third-party data. And BASF's multiple quality certifications, after-sales services are perfect, and manufacturers rely on it to ensure the quality and reliability of end point products.
Although Countertype is known as the benchmark, it also imitates its chemical structure and main agent composition, appearance, color, melting point or approximation, and there is no shortage of sales. However, its raw material purity, impurity types, auxiliary agent collocation and production control may not be equivalent to the original factory. Some Countertypes are produced in small private factories, or the pursuit of low cost, omitting the testing procedure. There seems to be no significant difference in the short term, but the effect of long-term application, exposure cycle, and aging protection may not be fully expected. Especially if the batch is stable, if there is a weak difference pool, there will inevitably be gaps in high-demand fields such as automobiles, photovoltaics, and communications.
If it is only used for general civilian use, and the technical requirements are not very strict, Countertype may be able to give it a try. If the project is related to safety, weather resistance, lifespan, or needs to pass a third-party authoritative certification, the original BASF should be used first. And Countertype has no formal long-term tracking data, and the quality commitment is limited.
In short, Countertype can be temporarily replaced. It is recommended to test in small batches to evaluate the actual light resistance and protection performance. If the test data is consistent with the original, and the source is reliable and the after-sales service is guaranteed, it can be replaced as appropriate. If the project is heavy on quality and refinement, it should be selected carefully and should not be completely replaced rashly. Only according to the actual application scenario, it is the best policy to carefully consider its replaceability.
What are the packaging and storage conditions for Countertype BASF Melagard MPP?
BASF Melagard MPP is a common light stabilizer in the chemical industry today, providing protection for polymers and plastic products under ultraviolet rays. If you have any questions about the packaging and storage conditions of its standard products, I would like to repeat them in text.
Its standard products are mostly made of high-density polyethylene plastic drums or multi-layer paper bags to prevent moisture penetration. The capacity of each bag is between 20 and 25 kilograms. The outer lining of the plastic bag is firmly sealed, and the special person checks it to prevent impurities from being mixed in. The packaging material must have excellent sealing performance to avoid the invasion of dust and water vapor. The outer wall of the storage container is often marked with the product name, batch number, production date and net weight for easy traceability and easy inventory. Its logistics transportation should also be handled with care to prevent damage and leakage.
As for storage conditions, a special warehouse should be set up to ensure ventilation, dryness and protection from light. Light stabilizer chemicals should not be exposed to high temperature, humidity and sunlight; only when stored in a cool place can their effectiveness be guaranteed. The temperature in the warehouse is usually 15 to 25 degrees Celsius, and the relative humidity should not be higher than 50%. In case of rainy season, plum rain and humid climate, desiccant should be added, or a dehumidifier should be used to adjust the climate to prevent agglomeration and deterioration. Do not mix with flammable, explosive and oxidizing agents when storing, and beware of cross-reaction. If the residue is not used up after opening, tighten the pocket in time and seal it for storage to prevent moisture absorption and moisture.
warehouse management requires frequent inspection. If the bag is found to be cracked or leaking, it should be isolated quickly and reported according to regulations. It cannot be delayed. Those who have exceeded the shelf life are recommended to undergo technical testing before they can continue to be used. On the whole, the emphasis is on dry sealing, sun protection and heat insulation. Daily prudent operation and regular inventory verification are the guidelines for packaging and storage. The above production methods ensure that Melagard MPP standard products are in storage and transportation, with stable properties and safe application.
