The hydroxyl groups at both ends of the molecule give the product chemical reaction activity, which can be used to prepare new materials or crosslink into elastomers through condensation reactions, enabling it to be used as a crosslinking control agent and diluent in room-temperature vulcanization silicone rubber and as a structuring control agent to interact with the active groups on the surface of silica fume.


Excellent surface properties and wide temperature range adaptability. The product has a low surface tension while maintaining the wide usage temperature range of fluorosilicone materials, enabling it to maintain elasticity and sealing performance in extreme temperature conditions.


3. Wide application fields


Product hydroxyl fluorosilicone oil 25O, with its unique performance combination, can play a key role in the following high-end application fields:


1. Structuring control agent for fluorosilicone rubber. The low-viscosity product is an excellent structuring control agent for fluorosilicone rubber. During the processing of fluorosilicone mixtures, the active groups on the surface of silica fume and other reinforcing fillers cause the rubber to gradually harden during storage, and this product can effectively prevent this structuring phenomenon from occurring, simplifying the processing technology. It can also be used for the structuring control of ordinary silicone rubber, enabling the silicone rubber to have certain fluorosilicone rubber properties, thus providing good cost performance.


2. Base gel and diluent for room-temperature vulcanization fluorosilicone rubber. The medium-high viscosity product can be used as the base gel and diluent for room-temperature vulcanization silicone rubber, used for the production of sealing and mold rubber that requires oil and solvent resistance. The sealants and potting compounds it produces can effectively cope with extreme environments such as high temperatures, high humidity and chemical corrosion in fields such as aerospace, automotive manufacturing, and electronic equipment.


III. Oil-resistant sealing and fuel oil system materials. The product is suitable for preparing oil-resistant sealing materials such as fuel oil hoses and other oil-resistant sealing products with good oil resistance, heat resistance and electrical insulation properties. In complex chemical environments such as aviation fuel, hydraulic oil and acids and alkalis, fluorosilicone rubber products can work stably for a long time.


IV. Packaging Specifications and Storage and Transportation Conditions


The product hydroxyl fluorosilicone oil 25O is packaged in plastic drums or galvanized iron drums, available in various specifications such as 1 kilogram, 5 kilograms, 20 kilograms, 50 kilograms and 200 kilograms, and transported as non-hazardous chemicals. It should be stored in a cool and dry environment, avoiding contact with acidic and alkaline substances to maintain neutrality, with a shelf life of 12 months.


V. Quality Assurance and Industrial Chain Value


The product hydroxyl fluorosilicone oil 25O has established a strict quality control system during production, conducting full-process testing on key indicators such as appearance, viscosity, specific gravity and refractive index to ensure consistency and reliability between batches.


With the continuous growth in demand for special elastomer materials that are oil-resistant and solvent-resistant in strategic industries such as new energy vehicles, aerospace and high-end equipment manufacturing, hydroxyl fluorosilicone oil, which combines end-hydroxyl reactive activity and excellent fluorosilicone synergy performance, is becoming a key raw material option for promoting the technological upgrading of high-end products such as fluorosilicone rubber structured control, room-temperature vulcanizing fluorosilicone rubber and oil-resistant sealing materials, providing strong raw material support for the independent innovation and industrial upgrading of domestic special organic silicon materials.
