In the field of materials science, innovative materials continue to emerge, injecting new vitality into the development of various industries. The IOTA-EO series of epoxy-terminated polyether silicone oils, as a unique organic silicon compound, is emerging in many fields with its unique molecular structure and excellent performance, and has become a model of innovative application of materials.
1. Unique molecular structure - the cornerstone of functional integration
The molecular structure of the IOTA-EO series of epoxy-terminated polyether silicone oils is exquisite. Its two ends are epoxy groups and polyoxyethylene ether segments, and the middle is a linear polysiloxane segment. This special structural design gives it a dual active center. The presence of epoxy groups enables it to undergo efficient curing reactions with amino-based curing agents, laying the foundation for its application in epoxy resin systems; and the polyoxyethylene ether segments bring hydrophilicity, breaking the limitations of poor hydrophilicity of traditional organic silicon materials and greatly expanding its application scenarios. The polysiloxane main chain in the middle inherits the excellent properties of organic silicon materials such as low surface tension, high flexibility, and high and low temperature resistance. The synergistic effect of the three makes the IOTA-EO series of epoxy-terminated polyether silicone oils a silicone epoxy resin intermediate with multiple functions.
2. Accurate technical indicators - meeting multiple needs
The IOTA-EO series currently has three standard product models, each with clear technical indicators and targeted uses:
IOTA-EO9000: Its viscosity range is 310-360cs, and the epoxy value is 0.20-0.22mmol/g. This model is particularly suitable for the synthesis of fluffy and elastic block silicone oils. In the textile industry, the block silicone oil synthesized with it is used in fabric finishing, which can give fabrics such as blankets and towels good fluffy feeling and resilience, and improve the comfort of the product.
IOTA-EO11000: The viscosity is 550-600cs, and the epoxy value is between 0.17-0.19mmol/g. This model is mainly used for the preparation of soft and smooth block silicone oils. Textiles such as underwear and sports fabrics that have extremely high requirements for skin touch can present an extremely soft and smooth feel after being finished with the block silicone oil synthesized by this model, bringing consumers the ultimate wearing experience.
IOTA-EO14000: It has a viscosity of 620-670cs and an epoxy value of 0.13-0.15mmol/g. This model focuses on the synthesis of smooth and soft block silicone oil. In the field of high-end clothing fabrics and leather finishing, the block silicone oil synthesized by it can make the surface of fabrics and leather smoother, soft and delicate to the touch, and improve the grade and added value of the product.
Not only that, considering the special needs of different customers, the company also provides customized services, which can accurately produce terminal epoxy polyether silicone oils with different molecular weights of 4K-20K to meet the needs of various complex application scenarios from low viscosity rapid response to high viscosity enhanced surface performance.
3. Significant features and advantages - standing out in the competition
Raw material substitution and cost control: Traditional block silicone oil synthesis often relies on terminal epoxy silicone oil, and the more expensive ED series polyether amines are required in the subsequent polymerization. The IOTA-EO series of terminal epoxy polyether silicone oil cleverly introduces hydrophilic polyether segments in the structural design. This innovation allows the efficient synthesis of block silicone oils in the subsequent block polymerization process by only using more affordable D series polyether amines, fatty amines, alcohol amines and other organic amines, which greatly reduces the cost of raw material procurement and provides strong support for enterprises to increase their profit margins.
Green process and environmental benefits: In the polymerization reaction with organic amines, the IOTA-EO series shows outstanding green advantages. The amount of organic solvent required for the reaction is very small, only 5% - 20% of the mass of the terminal epoxy polyether silicone oil, which can successfully initiate the reaction and generate uniform, transparent and stable high-content block silicone oil. Compared with traditional processes, the amount of organic solvents used is greatly reduced, which not only reduces production costs, but also significantly reduces the emission of volatile organic compounds (VOCs), which meets the current global strict requirements for green and environmentally friendly production and helps companies achieve sustainable development goals.
Efficient reaction and stable products: The end-epoxy polyether silicone oil has good compatibility with organic amines, which enables the two to react efficiently in a homogeneous state under the condition of a small amount of solvent or even no solvent. This sufficient and thorough reaction process effectively guarantees the stability and consistency of the finished product quality. Whether in the production of electronic packaging glue with strict requirements on product quality stability, or in the field of automotive coatings manufacturing, the IOTA-EO series can rely on this advantage to provide companies with reliable raw material guarantees and reduce losses caused by product quality fluctuations.
Product diversification and application expansion: End-epoxy polyether silicone oils with different molecular weights provide the possibility of synthesizing block silicone oils with diversified hand-feel styles. By accurately selecting products with suitable molecular weights, companies can customize block silicone oils with different hand-feel characteristics according to market demand to meet the needs of textile, leather and other industries for product diversification. For example, in the textile industry, the most suitable hand feel style can be formulated for different fiber materials and fabric uses to enhance the market competitiveness of the product.
Excellent modified performance: After quaternization modification, the IOTA-EO series products have made a qualitative leap in hydrophilicity and stability compared with ordinary quaternary ammonium salt modified silicone oils. In the application of products such as conditioners and fabric antistatic agents, its excellent hydrophilicity can make hair and fabrics smoother and easier to comb. At the same time, its excellent stability ensures that the product can continue to perform well after multiple uses and washings, bringing consumers a long-term use experience.
Resin performance optimization: In the water-soluble epoxy resin system, the end-epoxy polyether silicone oil IOTA-EO series can give full play to its structural advantages. Through effective combination with the resin, it can significantly improve the flexibility of the resin, reduce internal stress, and enhance the impact resistance and fatigue resistance of the resin. In fields such as electronic packaging and composite material manufacturing that have extremely high requirements for resin performance, this feature enables epoxy resin-based materials to better adapt to complex working environments and extend the service life of products.
