In the high-end industrial fields such as aerospace, automotive manufacturing, and electronic and electrical engineering, special materials that combine the excellent temperature resistance of silicone rubber and the outstanding oil and solvent resistance of fluorine rubber have always been the key to solving the sealing and protection problems in harsh conditions. The products we have launched, vinyl fluorosilicone oil 25V, as a fluorosilicone polymer with both vinyl terminations at both ends and trifluoropropyl side chains, demonstrate unparalleled industrial application value in high-end applications such as liquid fluorosilicone rubber, fluorosilicone potting compounds, and fluorosilicone release agents, providing crucial active intermediate raw materials for the development of special elastomer materials.


I. Core Structural Characteristics and Physical Properties of the Product


Vinyl fluorosilicone oil 25V is a fluorosilicone polymer with both vinyl terminations at both ends and trifluoropropyl side chains. This product offers multiple models to meet different application needs: the 25V-LF-XX series has a specific gravity of 0.99 and a refractive index of 1.40; the 25V-H has a specific gravity of 1.15 and a refractive index of 1.38; the 25V-HQ-XX has a specific gravity of 1.16 and a refractive index of 1.38; the 25V-HX-XX has a specific gravity of 1.24 and a refractive index of 1.38. The viscosity range covers from 50 to 50,000 square millimeters per second, allowing for customization of product viscosity and fluorine content as per requirements.


II. Core Performance Advantages and Application Mechanism


Vinyl fluorosilicone oil 25V, with its unique fluorosilicone molecular structure, exhibits the following core performance advantages in material applications:


Outstanding oil and solvent resistance. The trifluoropropyl groups introduced give the product oil resistance and solvent resistance, enabling it to maintain stable performance in complex media such as gasoline, lubricating oil, hydraulic oil, and various chemical solvents, making it the only special elastomer material that can be used in -60°C to 210°C fuel media or non-polar solvents.


High reactivity due to the vinyl terminations at both ends. The vinyl terminations at both ends of the molecule give it high reactivity, which can undergo silanol addition reactions with hydrogen-containing silicone oil to form a cross-linked network, and can also participate in various other reactions.


Low surface tension and excellent weathering aging performance. The introduction of trifluoropropyl groups gives the product better weathering and aging resistance.


III. Wide Application Areas


Vinyl fluorosilicone oil 25V, with its unique performance combination, can play a key role in the following high-end application areas, including:


1. Base gel raw material for liquid fluorosilicone rubber. The medium-viscosity product can be used to prepare liquid fluorosilicone rubber and is the main raw material for injection molding fluorosilicone rubber. Fluorosilicone rubber combines the excellent high and low-temperature performance of silicone rubber and the good oil and solvent resistance of fluorine rubber, having a wide temperature range and being widely used in oil-resistant sealing in aerospace, automotive, and shipbuilding industries.


2. Core component of fluorosilicone potting compounds. The low-viscosity product can be used to make fluorosilicone potting compounds, and the finished product can remain stable in gasoline and lubricating oil media, with low surface tension and the ability to penetrate the fine gaps of electronic components to achieve a gas-free encapsulation. It also has excellent insulation performance and weather resistance, providing reliable protection for electronic components.


3. Production raw material for fluorosilicone release agents. The low-viscosity product can also be used for the production of fluorosilicone release agents. The resulting release agent has a stable control of low release force and does not deteriorate after high-temperature treatment, far exceeding the temperature limit of traditional silicone oil release agents.


4. Materials for oil-resistant sealing and fuel oil hoses. The product is suitable for use as materials for oil-resistant, heat-resistant, and electrically insulating oil tank sealing materials and fuel oil hoses. In environments such as aviation fuel oil, hydraulic oil, and acid-base environments, fluorosilicone rubber products can work stably for a long time.


5. Platinum-active diluent for additively formed fluorosilicone rubber. The product is suitable as a platinum-based active diluent for reinforced sulfurized fluorosilicone rubber, effectively reducing the viscosity of the rubber compound without sacrificing the performance of the final product.


IV. Packaging Specifications and Storage Conditions


The product, 25V vinyl fluorosilicone oil, is packaged in plastic drums or galvanized iron drums. It is available in various specifications such as 1 kg, 5 kg, 20 kg, 50 kg, and 200 kg, and is transported as non-hazardous goods. It should be stored in a cool and dry environment, with a shelf life of 12 months.


V. Quality Assurance and Industrial Chain Value


During the production process of the product, 25V vinyl fluorosilicone oil, a strict quality control system has been established. Key indicators such as product appearance, viscosity, specific gravity, refractive index, and vinyl content are tested throughout the process to ensure consistency and reliability between batches.


With the continuous growth in the demand for oil-resistant and solvent-resistant special elastomer materials in strategic industries such as new energy vehicles, aerospace, and high-end equipment manufacturing, vinyl fluorosilicone oil, which combines high reactivity at the end group and excellent synergistic performance of fluorosilicon, is becoming a key raw material option for promoting the technological upgrading of high-end products such as fluorosilicone rubber, fluorosilicone potting compound, and fluorosilicone release agents. It provides strong raw material support for the independent innovation and industrial upgrading of domestic special organic silicon materials.
