The Future of Silicone Intermediates
In the dynamic world of silicone chemistry, Epoxy Polyether Silicone Oil (EPSO) stands out as a transformative intermediate. Combining the flexibility of polysiloxanes with the reactivity of epoxy groups, EPSO offers a pathway to synthesize block silicone oils with unprecedented properties. Whether enhancing epoxy resins or creating custom-tailored silicone formulations, EPSO is the key to unlocking new possibilities.

Technical Excellence
Our EPSO portfolio includes three flagship products, each optimized for specific applications:

• IOTA-EO9000: With a viscosity of 310–360 cs and an epoxy value of 0.20–0.22 mmol/g, it’s the go-to choice for fluffy, elastic block silicone oils.
• IOTA-EO11000: At 550–600 cs viscosity and 0.17–0.19 mmol/g epoxy value, it delivers soft, smooth finishes in block silicone oil formulations.
• IOTA-EO14000: The highest viscosity variant (620–670 cs) and epoxy value (0.13–0.15 mmol/g) are ideal for ultra-smooth, soft textures.
  For unique requirements, custom molecular weights (4K–20K) can be developed, ensuring precision in every application.

Innovative Advantages

1. Sustainable Synthesis: The inclusion of polyether segments reduces dependency on costly polyether amines, enabling the use of economical amines and alcoholamines.
2. Eco-Friendly Processing: Organic solvent usage is minimized to 5%–20% of the EPSO mass, cutting down emissions and boosting product concentration.
3. Universal Compatibility: EPSO’s seamless integration with organic amines allows for solvent-free or low-solvent reactions, ensuring uniformity and stability in finished products.
4. Customizable Performance: By adjusting molecular weights, a spectrum of block silicone oil textures can be achieved, from elastic to ultra-soft.
5. Superior Hydrophilicity: Quaternized EPSO variants outperform conventional silicone oils in water affinity and stability, ideal for personal care and textile applications.
6. Enhanced Epoxy Resin Properties: In water-soluble systems, EPSO improves flexibility and reduces stress, making it indispensable in coatings and adhesives.
