In the large family of silicone materials, long-chain alkyl silicone oil occupies an important position due to its unique molecular structure and performance. In its molecular structure, the main chain of silicon oxygen is connected to the long-chain alkyl group. This special structure gives it a series of excellent properties.
1. Excellent characteristics
Excellent lubricity: Long-chain alkyl silicone oil has weak intermolecular forces and low friction coefficients. It can form a uniform lubricating film on the surface of various materials, effectively reducing friction and wear. Whether it is between metals or between metals and plastics, rubber and other materials, it can show good lubrication effects.
Good demoulding properties: It has low affinity for the surface of molds and molded products, and can form an isolation layer between the two, making it easier for the product to be removed from the mold, and will not leave residues on the surface of the product, ensuring that the surface of the product is smooth.
Excellent hydrophobicity: The presence of long-chain alkyl groups makes long-chain alkyl silicone oil have a strong tendency to repel water. When it is coated on the surface of an object, it will form a continuous hydrophobic film, causing water to form water droplets on its surface and roll off, effectively preventing water from eroding and penetrating the object.
Good compatibility: It can be soluble in a variety of organic compounds and polymer materials, such as many common plastics, rubbers, resins, etc. This compatibility facilitates its application in different material systems.
Printability: Long-chain alkyl silicone oil can improve the wettability of the material surface, making it easier for inks, coatings, etc. to adhere and spread on its surface, thereby improving the quality of printing.
2. Wide application
Industrial lubrication field: In mechanical manufacturing, it is used for lubrication of high-speed running parts, reducing friction loss and extending the service life of equipment; in the automotive industry, it is used as a lubricant for engine, transmission and other parts to improve the performance of the car.
Plastic and rubber processing: As a release agent, it is widely used in the molding process of plastic and rubber products to ensure smooth demolding of the product; at the same time, due to its compatibility, it can be used as a plasticizer or modifier to improve the flexibility and processing performance of plastics and rubber.
Textile industry: It is used for the finishing of fibers and fabrics, giving the fabric a soft and smooth feel, while improving the waterproof performance of the fabric; in yarn production, it can be used as a lubricant to reduce friction between yarns and reduce the breakage rate.
Construction field: used as a water repellent for building materials, such as coating long-chain alkyl silicone oil on the surface of concrete, masonry and other materials, which can effectively prevent rainwater penetration and improve the durability of building materials.
Daily chemical products: In skin care products, long-chain alkyl silicone oil can be used as an emollient to improve the product's application and moisturizing properties, making the skin feel smooth and delicate; in hair care products, it can repair damaged hair and increase the hair's luster and smoothness.
