1,3,5-Trimethyl-1,3,5-tris(3,3,3-trifluoropropyl)-cyclotrisiloxane

Product Overview

1,3,5-Trimethyl-1,3,5-tris(3,3,3-trifluoropropyl)-cyclotrisiloxane is a premier cyclic siloxane monomer engineered for the production of high-performance fluorosilicone polymers. This specialized chemical intermediate serves as the foundational building block for creating materials that demand exceptional stability under extreme environmental conditions. By incorporating trifluoropropyl groups into the siloxane backbone, manufacturers can achieve a unique balance of organic polymer flexibility and inorganic-like resistance to harsh chemicals.

Our facility produces this compound with rigorous quality control standards, ensuring a minimum purity of 99.5%. This high level of purity is critical for downstream polymerization processes, where impurities can negatively affect molecular weight distribution and final elastomer performance. We supply this material globally to industries that cannot compromise on material integrity, including aerospace engineering, automotive manufacturing, and specialized petrochemical applications.

Key Performance Features

The incorporation of fluorine atoms into the siloxane structure imparts distinctive properties that standard silicones cannot match. This product enables the synthesis of polymers with enhanced resistance to fuels, oils, and solvents, making it indispensable for sealing solutions in engine compartments and hydraulic systems. The low surface tension associated with fluorine content also provides superior hydrophobicity and oleophobicity.

• Exceptional thermal stability across a wide operating temperature range.
• Superior resistance to aromatic hydrocarbons, fuels, and lubricating oils.
• Excellent weatherability and UV resistance for outdoor applications.
• Low surface energy contributing to effective mold release and non-stick properties.
• Consistent batch-to-batch quality supported by comprehensive COA documentation.

Technical Specifications

We adhere to strict manufacturing protocols to ensure every shipment meets the defined physical and chemical parameters. The following table outlines the standard specifications for this grade. Custom specifications may be available upon request for large-scale industrial projects.

Industrial Applications

This monomer is primarily utilized in the ring-opening polymerization process to manufacture various fluorosilicone products. The resulting polymers are essential in sectors where material failure is not an option. Common end-products include fluorosilicone oils, rubbers, greases, and defoamers. In the automotive industry, these materials are used for fuel system O-rings and gaskets that must withstand constant exposure to gasoline and diesel. In aerospace, they provide reliable sealing in hydraulic systems exposed to skydrol and other aggressive fluids.

Furthermore, the chemical resistance profile makes these derived materials suitable for petrochemical processing equipment and machinery exposed to acidic or alkaline environments. The ability to maintain elasticity and sealing force after prolonged exposure to solvents distinguishes fluorosilicones from standard vinyl or phenyl silicones.

Storage and Handling

To maintain product integrity, storage conditions must be carefully controlled. The material should be kept in its original unopened container at temperatures of 25℃ or below. Under these conditions, the shelf life is guaranteed for one year from the production date. Expired products should not be discarded immediately but can be utilized after passing rigorous quality testing to confirm specifications remain within acceptable limits. As a classified dangerous good (Class 6.1), all handling must comply with local safety regulations regarding toxic substances.

Quality Assurance and Supply

As a global manufacturer, we prioritize supply chain reliability and technical support. Each batch is accompanied by a Certificate of Analysis (COA) detailing test results for purity, moisture, and identity. We offer flexible packaging options, with the standard unit being a 220Kg iron drum, suitable for bulk industrial consumption. Our logistics network ensures timely delivery to production facilities worldwide, supporting continuous manufacturing operations without interruption.
