Diethyl Phosphinic Acid Aluminum, with the CAS number 225789-38-8, is a high - quality chemical product. It is a type of organophosphorus flame retardant. The product is presented in a solid form, usually in a fine powder or granular appearance. It has good thermal stability, which allows it to maintain its chemical properties under relatively high - temperature conditions.
Chemically, it has a specific molecular structure that contributes to its excellent flame - retardant performance. The molecular formula can be further analyzed to understand its composition in detail. In terms of purity, our product is of high quality, ensuring that it can meet the strict requirements of various applications. The particle size of the powder is carefully controlled to guarantee uniformity and good dispersion when it is used in different materials.
One of the primary uses of Diethyl Phosphinic Acid Aluminum is as a flame retardant in the plastics industry. It can be added to various plastic materials such as polyamides, polyesters, and polycarbonates. By incorporating this product into plastics, the flammability of the plastic is significantly reduced. This is crucial for applications where fire safety is a concern, such as in the manufacturing of electronic equipment casings, automotive interior parts, and electrical wiring insulation.
In the textile industry, it can be used as a flame - retardant finishing agent. Fabrics treated with Diethyl Phosphinic Acid Aluminum can achieve better fire - resistant properties, which are suitable for making protective clothing, curtains in public buildings, and upholstery materials.
It also has potential applications in the coating industry. When added to coatings, it can enhance the fire - resistance of the coated surface, providing an extra layer of protection for buildings, furniture, and other objects.
When using Diethyl Phosphinic Acid Aluminum in the plastics industry, it is typically added during the plastic compounding process. First, determine the appropriate dosage according to the specific requirements of the plastic material and the desired level of flame - retardancy. Usually, the dosage ranges from a few percent to a certain proportion depending on the plastic type. Then, mix the product evenly with the plastic resin. This can be achieved through mechanical mixing methods using specialized mixing equipment to ensure that the flame retardant is well - dispersed in the plastic matrix.
In the textile industry, it can be applied through a padding process. Prepare a solution containing a certain concentration of Diethyl Phosphinic Acid Aluminum. Immerse the fabric in the solution, and then pass it through a padding mangle to remove excess liquid. After that, the fabric needs to be dried and cured under appropriate temperature and time conditions to ensure the effective bonding of the flame retardant to the fabric fibers.
For the coating industry, add the product to the coating formulation during the production process. Stir it thoroughly to ensure uniform dispersion in the coating. The coating can then be applied to the surface using conventional coating application methods such as spraying or brushing.
Case 1: A plastic manufacturing company was producing polyamide parts for electrical connectors. They used Diethyl Phosphinic Acid Aluminum as a flame retardant. After adding the appropriate amount, the polyamide parts passed the UL 94 V - 0 flammability test, which is a very strict standard in the industry. This not only improved the safety of the electrical connectors but also met the requirements of their customers in the electronics market. The production efficiency was also maintained because the product has good compatibility with the polyamide resin, and there was no significant impact on the processing properties.
Case 2: A textile factory treated cotton fabrics with Diethyl Phosphinic Acid Aluminum. The treated fabrics were used to make curtains for a large - scale convention center. In a fire - simulation test, the treated curtains showed significantly reduced flame spread compared to untreated ones. This increased the safety level of the convention center and also provided more evacuation time in case of a fire.
