Custom Manufacturing, Project Outsourcing, your Trusted Partner from China
Octamethylcyclotetrasiloxane (D4), bearing the CAS number 556-67-2, is a colorless, viscous liquid that plays a vital role in the chemical industry, primarily as a precursor to silicone polymers. As a leading manufacturer and supplier of Octamethylcyclotetrasiloxane in China, NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to providing high-quality D4 that meets the demanding specifications of various industrial applications. Understanding its properties is key to leveraging its full potential.
Chemically, D4 is an organosilicon compound with the formula [(CH3)2SiO]4. It is one of the most common cyclic siloxanes, characterized by its relatively low volatility and inert nature under standard conditions. Its melting point is around 17-18 °C, and it boils at approximately 175-176 °C, indicating its liquid state at room temperature. The density is about 0.956 g/mL at 25 °C, and its refractive index is 1.396 at 20 °C. These physical properties are crucial for handling and processing D4 in manufacturing settings. When you choose to buy D4 siloxane from us, you receive material with consistent and verified specifications.
The primary application of Octamethylcyclotetrasiloxane lies in its ability to undergo ring-opening polymerization. This chemical transformation is the foundation for producing polydimethylsiloxane (PDMS), which then serves as the building block for a vast array of silicone materials. These include silicone fluids used in lubricants and hydraulic systems, silicone elastomers for seals and gaskets, and silicone resins for coatings and adhesives. For researchers and production managers looking to purchase Octamethylcyclotetrasiloxane for polymerization, our high-purity product ensures efficient and predictable reactions.
While historically used in personal care products, the industrial applications remain a significant focus for NINGBO INNO PHARMCHEM CO.,LTD. We serve industries that require a dependable supplier of CAS 556-67-2 for producing performance materials. Our commitment as an Octamethylcyclotetrasiloxane manufacturer is to provide a reliable source of this essential chemical. We encourage potential clients to request a quote for Octamethylcyclotetrasiloxane to experience our competitive pricing and exceptional service.
In summary, the unique properties of Octamethylcyclotetrasiloxane (D4) make it an invaluable intermediate in the chemical industry. NINGBO INNO PHARMCHEM CO.,LTD. is your trusted partner for sourcing this critical compound, offering high purity, competitive prices, and reliable supply from China.
