In the industrial fields such as high-temperature die-casting, metal processing, and rubber-plastic molding, the temperature resistance and cleanliness of release agents and lubricants directly determine the mold life, workpiece quality, and production efficiency. Our company has launched the product long-chain alkyl modified silicone oil 28027, which is a long-chain alkyl and benzyl dual-modified multi-viscosity gradient silicone oil. With its excellent high-temperature resistance and low carbon deposition performance, and good compatibility with mineral oil and synthetic resins, it demonstrates significant application value in high-temperature die-casting release, metal lubrication, rubber-plastic modification, chemical fiber spinning, and personal care. It provides customers in various industries with high-performance multi-functional silicone oil options.


I. Product Series Specifications and Core Physical and Chemical Properties


The long-chain alkyl modified silicone oil 28027 is a light yellow transparent liquid with a viscosity range of 600 to 4500 centistokes, a refractive index of 1.465 to 1.5100, and a volatile content of less than 10% at 150 degrees Celsius for three hours. This product is a multi-viscosity gradient series silicone oil modified by both long-chain alkyl and benzyl. Compared to ordinary alkyl silicone oil, the introduction of the benzyl structure significantly improves the product's high-temperature resistance, wear resistance, and lubrication performance, resulting in a significant reduction in carbon deposition and slag formation during high-temperature processing.


II. Core Performance Advantages


The long-chain alkyl modified silicone oil 28027, with its unique alkyl-aryl co-modification structure, exhibits the following core performance advantages in various application systems:


Excellent lubrication, wear resistance, and high-temperature low carbon deposition performance. The product shows excellent lubrication durability and anti-carbon deposition ability in high-temperature conditions, especially suitable for aluminum, zinc, and magnesium alloys in high-temperature die-casting molding processes. The indicator of less than 10% volatile content ensures less volatile substances and lower smoke during high-temperature processing, improving the working environment in the workshop.


High organic compatibility and friendly to subsequent processes. The product has excellent compatibility with mineral oil, various synthetic resins, and paraffin, and after release, the workpiece can directly undergo subsequent processing such as printing, painting, and embossing, without interference from subsequent coatings, effectively avoiding poor coating adhesion and surface defects caused by residual release agents.


Hydrophobic modification and smooth adjustment performance. The product can give the treated substrate surface a hydrophobic, smooth, and glossy effect, performing particularly well in plastic brightening, chemical fiber processing, and personal care formulations.


III. Wide Application Areas


The long-chain alkyl modified silicone oil 28027, with its multi-functional performance combination, can play a key role in the following application areas, specifically including:


1. High-temperature die-casting release and metal lubrication. This product is an important component for preparing water-based metal die-casting release agents and lubricants, especially suitable for aluminum, zinc, and magnesium alloys in hot forming processing. Its excellent high-temperature resistance and low carbon deposition characteristics can effectively protect the mold, extend the mold life, and improve the surface finish of the castings, reducing the frequency of stoppage for cleaning due to carbon deposition.


2. Rubber-plastic processing and plastic modification. In plastic modification, injection molding, and rubber processing, this product can be used as an efficient release agent, lubricant, and brightener, improving the surface gloss and release smoothness of the products, while its good organic compatibility ensures the subsequent printing and coating performance of the products.


3. Chemical fiber spinning oil agent. This product can be used as an important component of chemical fiber spinning oil agents, improving the smoothness and bunching of fibers, reducing breakage and fuzz, and increasing spinning efficiency.


4. Oil additives and lubricating greases. This product can be used as an additive for mineral oil and synthetic lubricating oils, improving the high-temperature stability and lubrication performance of the oil.


5. Personal care and cosmetics. This product can give formulations good smoothness and gloss, suitable for skincare, hair care, and makeup personal care product formulations.


IV. Packaging Specifications and Storage Conditions Product Long-Chain Alkyl Modified Silicone Oil 28027 is packaged in standard 180-kilogram plastic drums. Customized small drum and ton drum specifications can be provided according to customer requirements. The product should be sealed and stored in a dry, cool, and well-ventilated warehouse, away from open flames, high-temperature heat sources, and direct sunlight. It should be transported as an ordinary organic silicone liquid chemical product to prevent packaging damage and leakage. Under the condition of intact original packaging and sealing, the product has a validity period of 24 months.


V. Quality Assurance and Industry Application Value


During the production process of product long-chain alkyl modified silicone oil 28027, a strict quality control system has been established. Key indicators such as product appearance, viscosity, refractive index, and volatile matter are tested throughout the process to ensure consistency and reliability between batches. As the casting, metal processing, and rubber-plastic molding industries continue to develop towards higher temperatures, precision, and cleanliness, the demand for silicone oil products with both high-temperature resistance, low carbon deposition, organic compatibility, and multi-functional properties is steadily increasing. Product long-chain alkyl modified silicone oil 28027, with its structural advantages of alkyl-aryl dual modification, multi-viscosity gradient series specifications, and wide industry applicability, is becoming an important solution for customers in multiple fields in the selection of high-temperature lubrication demolding and functional modification additives, providing strong support for promoting the quality improvement and process optimization of the downstream industry.
