Leveraging its mature fluorochemical industry chain resources and product supply capabilities, Jiayuan Chemical continuously focuses on the application and development of high-purity fluorine materials in advanced manufacturing, providing global customers with a variety of high-quality fluoride products, including high-purity calcium fluoride. In recent years, with the rapid development of semiconductor manufacturing, precision optics, laser technology, and high-end testing equipment, 99.99% high-purity calcium fluoride (CaF₂) is becoming an important basic material in the advanced manufacturing industry chain. Compared to ordinary industrial-grade calcium fluoride, high-purity calcium fluoride places higher demands on impurity control, material stability, and optical performance, and its application areas are gradually expanding from traditional industries to high-value fields such as semiconductors, optoelectronics, and high-end optics.

D3F, or 1,3,5-tris(3,3,3-trifluoropropyl)trimethylcyclotrisiloxane , CAS No. 2374-14-3 , molecular formula C₁₂H₂₁F₉O₃Si₃ , is a fluorinated cyclic siloxane monomer. Its molecular structure possesses both a siloxane structure and a trifluoropropyl side chain, allowing the introduction of fluorine through ring-opening polymerization and other methods. It is an important basic raw material for the preparation of fluorosilicone rubber, fluorosilicone oil, and related fluorosilicone materials. Publicly available technical information indicates that D3F is mainly used in the manufacture of fluorosilicone rubber and fluorosilicone fluids, and can also be used as a comonomer to prepare different types of fluorinated siloxane materials.

Fluorosilicone rubber

Fluorosilicone rubber is one of the most important applications of D3F. Through polymerization, D3F can introduce a trifluoropropyl structure, giving the material both the flexibility of silicone rubber and the media resistance provided by the fluorinated structure. Therefore, fluorosilicone rubber can be used in sealing and elastomer products that require high resistance to oil, chemical media, and a wide temperature range.

Fluorosilicone oils and specialty silicone oils

D3F is also an important basic monomer for fluorosilicone oils. Fluorosilicone oils can be used for lubrication, mold release, defoaming, and as functional fluids in special industrial environments. Compared to ordinary silicone oils, the fluorinated structure can impart different surface and media resistance properties to materials, thus having certain application value in the field of high-performance industrial materials.

Fluorosilicone resins and functional materials

D3F can also be copolymerized with other siloxane monomers to prepare fluorosilicone resins and functional silicon materials with specific properties by adjusting the fluorine content and molecular structure. These materials can be further used in coatings, seals, surface treatments, and other special industrial applications.

D3F's direct purchasing customers are mainly concentrated in fluorosilicone rubber manufacturers, fluorosilicone oil manufacturers, silicon material companies, specialty sealing material companies, and fluorosilicone material R&D companies . For these customers, in addition to price, they are more concerned about purity, impurity content, batch stability, polymerization performance, and long-term supply capability when purchasing D3F.

With the increasing demand for high-performance elastomers and functional silicon materials from the automotive, electronics, aerospace, special equipment, and high-end industrial manufacturing industries, the market demand for D3F, as an important upstream monomer for fluorosilicone materials, is expected to further expand along with the development of downstream materials industries.
